Next Thing CHIP board and corresponding PocketCHIP portable Linux computer have been relatively popular due to their inexpensive price for the feature set, as for $9, you’d get an Allwinner R8 ARM Cortex A8 processor, 512MB flash, 4GB NAND flash, WiFi & Bluetooth connectivity, and plenty of I/Os, which made it very attractive for IoT applications compared to other cheap boards such as Raspberry Pi Zero and Orange Pi One. The first board was mostly designed for hobbyists, but company has now designed a new lower profile system-on-module called CHIP Pro based on Next Thing GR8 SIP combining Allwinner R8 SoC with 256MB DDR3 RAM that can be used for easy integration into your own hardware project.
- SIP – Allwinner R8 ARM Cortex A8 processor @ up to 1.0 GHz with Mali-400 GPU + 256MB DDR3 RAM (14×14 mm package)
- Storage – 512MB SLC NAND flash, 1x micro SD port
- Connectivity – 802.11 b/g/n WiFi + Bluetooth 4.2 with chip antenna and u.FL antenna connector
- USB – 1x micro USB port for power and serial console access
- Expansion – 2x 16-pin with 2x UART, parallel camera interface, I2C, SPI, 2x PWM, USB 2.0 OTG, USB 2.0 host, 2x microphone, 1x headphone
- Power Supply – AXP209 PMU supporting USB power, Charge in, and 2.9 to 4.2V LiPo battery
- Dimensions – 45 x 30 mm
- Certifications – CE and FCC part 15
The module is pre-loaded with the company’s Linux based GadgetOS operating system, but custom firmware flashing is available for orders of 1,000 modules or more. Potential applications include physical computing, voice recognition, smart consumer devices, portable audio devices and so on. Software support should be identical to what you already get in CHIP board, and you can already find some hardware design files specific to CHIP Pro on Github including datasheets for the system-on-module and Allwinner GR8 SIP.
In order to help you getting started as fast as possible, a development kit is also available with a baseboard and two CHIP Pro modules. The baseboard include a 5V-23V power jack, a 3.5mm audio jack, a micro USB port, a USB host port, some LEDs, a power button, and female headers for easy access to all I/Os.
CHIP Pro SoM will start selling for $16 in December of this year without minimum order quantity, and no volume discount, e.g. if you buy 1 million SoMs, you’d have to pay 16 million dollars. One issue with CHIP board is that if you asked Allwinner for a quote for module used in the board, it would cost more or about the same as the board itself. Allwinner/Next Thing GR8 is completely different, as you can actually buy it for $6 (including AXP-209 PMIC) to integrate into your own project. The development kit is available now for $49. More technical details and purchase links can be found on the product page.
