Some time ago after searching for hours to find a simple SoC wich can run Linux and is available in a TQF package, I stumbled across the Allwinner V3s. Orignally designed for the Action Camera / Dash cam and IP camera market. The V3s fulfilled all my needs for my embedded project. Since there is no development board for the V3s I created the Blueberry PI.
The V3s is a very unique SoC, it can be called the true 3 in 1 chip solution. Beside the ARM Cortex-A7 @ 1.2GHz, the V3s has built-in 64 Megabyte of RAM and an Ethernet PHY.
Thanks to the built-in RAM, there is no need for a messy memory layout. This saves space and more important expensive PCB layers. The Blueberry Pi is routed as 2 layer board.
Since the V3s has a parallel RGB interface, it can directly drive LCD's like the AT050TN33 (480x270) or other even bigger LCD's like the HW800480F-3E-0B-10 (800x480). The Blueberry PI is compatible with every 40 pin RGB LCD.
Since many people were really interested in buying a Blueberry PI, I fixed some minor issues on the current PCB and ordered new PCB's. I will start selling the Blueberry PI on Tindie in the near future.
