Last year, Octavo Systems introduced OSD3358 System-in-Package (SiP) that includes Texas Instruments Sitara AM3358 processor, 256MB to 1GB RAM, a PMIC and an LDO into a single package. Since then the SiP has been found in BeagleBone Black Wireless and BeagleBone Blue, and at the time of launch there was also some development around PocketBone, a tiny open source hardware Smalls mint tin sized board based on OSD3358, which is smaller than a CHIP board, but a little bigger than NanoPi NEO board.
There’s now been some progress with prototypes of the board manufactured with the following specifications:
- SiP (System-in-Package) – Octavo Systems OSD3358 with TI Sitara AM3358 ARM Cortex-A8 processor @ up to 1 GHz, PowerVR SGX530 GPU, PMIC + LDO, and 512MB DDR3
- Storage – micro SD slot
- USB – 2x micro USB port one for power, one OTG port
- Expansion – 10-pin header (unpopulated) with SPI, I2C, UART, GND, and 3.3V signal
- Misc – Power & reset buttons
- Power Supply – 5V via micro USB port; 4-pin header for 3.7 LiPo battery
- Dimensions – ~54mm x ~33mm (fits in Altoid Smalls mint tin box).
The first version of the board was designed with Eagle, but the schematics and PCB layout have been redesigned with KiCad open source software instead, and all hardware design files are released under CERN Open Hardware License v1.2. The boards should be able to run any distributions that works on BeagleBone Black derived boards such as Debian, Angstrom, Ubuntu, etc…
PocketBone is not for sale yet, but if you are interested you could fill out a survey, which could either end-up starting a group buy, or – if there is more interest than expected – a crowdfunding campaign. More details about the project can be found on its hackaday.io page.
