This document provides technical details on the module and basic guides for getting started with working with C.H.I.P. Pro. To get the most out of developing and designing for C.H.I.P. Pro, we recommend the C.H.I.P. Pro Development Kit.
Overview
C.H.I.P. Pro is a breadboard-friendly and surface-mount-ready computer designed from the ground up to power the next generation of smart devices.
C.H.I.P. Pro is powered by GR8, a system-in-package (SiP) that was designed by us at Next Thing Co. GR8 features a 1GHz Allwinner R8 ARM Cortex-A8 processor, Mali400 GPU, and 256MB of Nanya DDR3 DRAM. in a 14mm x 14mm FBGA package. C.H.I.P. Pro adds to the GR8 with 512MB of high-speed NAND storage, WiFi and Bluetooth connectivity, power and battery management, pins for popular I/O busses, USB gadget, the verstatility of mainline Linux, all on a compact footprint.
The module offers all the popular interfaces you’d expect. With two UARTs, a Two Wire Interface, a parallel camera interface, SPI, two PWM channels, a USB 2.0 OTG, and a USB 2.0 Host, C.H.I.P. Pro is packed full of opportunity. Comprehensive audio handling includes a built-in 24-bit ADC/DAC for stereo audio in and out, One Wire Audio digital out, and I2S digital audio for interfacing with professional audio DACs.
C.H.I.P Pro is CE, IC, and FCC part 15 modularly certified, making integration into end products easy. The on-board Realtek 8723DS combination module provides compliant Wi-Fi B/G/N and Bluetooth 4.2 Low-Energy connectivity. A software controlled antenna path selects between the on-board chip antenna or a uFL antenna connector where several pre-certified antennas can be added to boost wireless transmit and receive range.
Charge or power from an AC/DC adapter or power it from USB or a rechargable battery. On-board Power management with the AXP209 provides plenty of power options to better match your applications: mobile, industrial, and low-power are all possible with C.H.I.P. Pro.
C.H.I.P. Pro is rated to operate between 2.9V-6V in temperatures ranging between 0 and 70 degrees Celsius and measures 45mm x 30mm.

Get Working With C.H.I.P. Pro
Power In, Power Out
C.H.I.P. Pro can be powered in a few ways, all managed by the AXP209 power management circuit. For simple applications on the test desk, power can be provided over the micro USB connector from a USB power supply or powered USB hub. But C.H.I.P. is for building, and depending on the nature of your product, there are different power options to make it easier to make with C.H.I.P. Pro.
- CHG-IN - connect 4.8 to 6 volts of power to this pin (and GND) to provide power for C.H.I.P. Pro. If you have a Lithium Polymer (LiPo) battery connected to BAT, then power provided to CHG-IN will also charge the battery.
- BAT - connect a 3.7 volts Lithium Polymer (LiPo) battery to this pin (and GND) to provide power to C.H.I.P. Pro and receive charge from power inputs.
- VBUS - connect 5 volts to this pin (and GND to pin 53) to provide power to C.H.I.P.. Power connected to VBUS will also charge a battery, just at a slower rate than from CHG-IN
C.H.I.P. Pro has three options for providing power to peripherals and sensors.
- VCC-3V3 - provides 3.3V for sensors.
- IPSOUT - the Intelligent Power Select provides up to 2.5 amps at up to 5 volts, depending on power provided at CHG-IN or VBUS. If a 3.7V LiPo battery is the only source of power, IPSOUT will provide a bit less than 3.7 volts. In general, the voltage at IPSOUT is a bit less than voltage in, with a max voltage of 5 volts.
- PWRON - connect to ground to turn C.H.I.P. Pro on and boot the operating system.
If you need to provide power to a USB device connected to USB1, connect IPSOUT to an appropriate switching regulator to the USB connector pad on your circuit board.
Powering Off
Ideally C.H.I.P. Pro should be powered off through a terminal window using the poweroff command. Alternatively, connect PWR pin to GND for 7-10 seconds to power off or disconnect power supply.
Get an Operating System
Like its larger brother C.H.I.P., C.H.I.P. Pro’s GR8 SiP can run mainline Linux. This provides security, flexibility, robust tools, and open-source options for getting your product working. In the interest of power consumption and storage space, we have several options to best fit your production.
Gadget OS
There are several examples of the Gadget OS for the Developer’s Kit. These examples are designed around the hardware on the Developer’s Kit board. If you are building a circuit that incorporates mics and LEDs you can start with these examples and a bare C.H.I.P. Pro. Read more in the developer’s kit documentation
Debian
We provide a standard Debian distribution, complete with all the package managers and conveniences you know and love. This package is ideal for development, since it is more flexible than the buildroot-based Gadget OS. However, you will want to keep track of your dependencies to more easily transition to the more nimble Gadget OS.
Things you will need
- C.H.I.P. Pro
- Standard-USB to micro-USB connector
- An appendage to hold down the FEL button
- Separate computer with Chrome or Chromium browser
Flash
Visit our OS flash site at flash.getchip.com in Chrome or Chromium browser. Hold down the FEL button on C.H.I.P. Pro and follow all the instructions in the browser. If you haven’t already, you’ll be asked to install the C.H.I.P. Flasher Plug-in for Chrome.
Use It
Now that you have power and an operating system, you can connect to your C.H.I.P. Pro to test software and hardware, customize it, or load new software. There are two very important connections for this: serial and network.
Serial Connection
The most basic connection to C.H.I.P. Pro is a serial connection controlled through a host computer’s terminal program.
UART
Things you will need
- USB-UART cable (for example)
- Drivers
- Soldering gun
- Solder
- Pin headers
- Computer with monitor (for example, a C.H.I.P.!)
- Terminal program for Windows such as Cygwin or PuTTY (OS X and Linux have terminals built-in)
A UART to USB serial connection between C.H.I.P. Pro and your computer offers the most comprehensive look at what’s happening in C.H.I.P. Pro as it boots, since you can get all message output from the moment it starts booting. You’ll need a USB to UART cable and the appropriate drivers for your computer’s OS.
For example, this cable uses the Prolific hardware, with drivers available on their site. Another popular chipset for these cables is FTDI.
Connect the cable to your computer and the UART pins on C.H.I.P. Pro. You’ll need to solder some headers onto C.H.I.P. Pro for a reliable connection to the loose wires on the cable. The black cable goes to ground, green is usually RX, and white is usually TX, but there’s no guarantee. So, make sure to check the manufacturer’s product description for the correct pinouts.
From your computer’s terminal use the command:
screen /dev/tty.usbserial 115200 #OS X
screen /dev/ttyUSB0 115200 #Linux
Another popular program besides screen is cu.
For Windows read our guide on connecting with PuTTY or Cygwin.
USB Gadget Serial
Things you will need
- USB A to micro-USB cable (for example)
- Computer with monitor (for example, a C.H.I.P.!)
- Terminal program for Windows such as Cygwin or PuTTY (OS X and Linux have terminals built-in)
If your OS is configured for Gadget serial, this is usually the easiest way to get inside C.H.I.P. Pro’s software. While you won’t be able to get boot messages, since the serial emulation won’t be ready, all you need is a USB A to micro-USB cable to connect C.H.I.P. Pro to your computer. From your computer’s terminal:
screen /dev/tty.usbmodem1440 115200 #OS X
screen /dev/ttyACM0 115200 #Linux
Note that for OS X you either need to list out all the tty devices with ls /dev/tty.usbm* to find the actual ID or use the tab key to autocomplete, like screen /dev/tty.usbm <tab>.
For Windows read our guide on connecting with PuTTY or Cygwin.
Log In
Once you have connected via serial you’ll be prompted for a username and password. The defaults are chip and chip. Change your password with passwd.
Network
Once you have connected to C.H.I.P. Pro with a serial connection, you can set it up for network access. How this happens depends on the OS you have loaded onto C.H.I.P. Pro. Most likely you’ll be able to make basic connections to a WiFi network using either connman or nmcli in the command line.
Connman
The basic commands to connect are done in a connman terminal. You can learn more about connman here
sudo connmanctl # enter the connman terminal
>enable wifi # turn on wifi
>scan wifi # find networks
>agent on # let connman prompt for a password when needed
>services # list all the visible networks so you can get the wifi_ id string
>connect wifi_7cc70905cd77_4e5443_managed_psk #connect to wifi_ id, connman will then prompt for password
>quit # get back to linux terminal
If your network does not have a password (ends with managed_none), you can connect using the wifi_ id that does not have the word “hidden” in it.
Confirm your connection with ping -c 4 8.8.8.8 and get your IP address from the wlan0 line from ip a.
ssh on buildroot
Once you have your C.H.I.P. Pro on the network, chances are that you’ll want to use ssh to connect to it. You can ssh chip@<ip address>. However, you’ll probably want to switch to root once you are in. You can do that with the command su and use root as the password.
nmcli
You may find nmcli is the gateway to your network if you are using a Debian linux image on C.H.I.P. Pro. There’s a lot of information about nmcli on the archlinux site. If nmcli is what you need, here are the commands you can use to connect to a network using your serial connection in the terminal:
sudo nmcli d wifi # list visible wifi networks
sudo nmcli d wifi connect "Network SSID Name" password "Your Password" ifname wlan0 # if network is hidden add this to end: hidden yes
ssh on debian
If you want to connect to C.H.I.P. Pro with ssh you will probably find it convenient to setup a unique name for your C.H.I.P. Pro. This gist has a simple script to make this easy.
ping!
It’s always reassuring to check that you have a connection with ping:
ping 8.8.8.8 #google dns server
Access I/O via sysfs
GPIO Input
These lines of code will let us read values on pin CSIDO, which corresponds to pin 132 in the linux sysfs (CSID0-CSID7 have numbers 132-139) First, we tell the system we want to listen to this pin:
sudo sh -c 'echo 132 > /sys/class/gpio/export'
View the mode of the pin. This should return “in”:
cat /sys/class/gpio/gpio132/direction
Connect a jumper wire or switch between Pin CSID0 and GND. Now use this line of code to read the value:
cat /sys/class/gpio/gpio132/value
GPIO Output
You could also change the mode of a pin from “in” to “out”
sudo sh -c 'echo out > /sys/class/gpio/gpio132/direction'
Now that it’s in output mode, you can write a value to the pin:
sudo sh -c 'echo 1 > /sys/class/gpio/gpio132/value'
If you attach an LED to the pin and ground, the LED will illuminate according to your control messages.
GPIO Done
When you are done experimenting tell the system to stop listening to the gpio pin:
sudo sh -c 'echo 132 > /sys/class/gpio/unexport'
Finding GPIO Pin Names
You can calculate the sysfs pin number using the Allwinner R8 Datasheet, starting on page 18.
The letter index is a multiple of 32 (where A=0), and the number is an offset. For example PE4 is CSID_D0 so
E=4
(32*4)+4 = 132
Therefore, listening to CSID0 in sysfs would begin with
sudo sh -c 'echo 132 > /sys/class/gpio/export'
Open Source
