Strawberry cake is a small, cheap embedded ARM board. Unlike the Raspberry Pi, it is real close. It is a board design that challenges you to assemble it yourself, to practice your fine-pitch SMD soldering techniques. It can be assembled with a normal soldering station, or - better - reflow soldered. Ongoing miniaturisation is a FACT, if you want to do electronics without being stuck in the 80's, you need SMD!

It will not run Linux since there is not enough memory, but it will spin circles around arduino's. It is made for the STM32 family members that come in 64pin TQFP packages, and have on-board USB, and optionally SDIO.

It features

  • a USB mini-B connector
  • a single-wire debug (SWD) connector for ... debugging
  • a micro-SD card slot (only SDIO mode)
  • place for pin-headers
  • reset button
  • user button
  • two LED's

Compared to an Arduino

  • it teaches you to build a DIY-professional design
  • can do properly what needed dirty hacks for on Arduino
  • can do dirty hacks that were out-of-reach on Arduino
  • has in-circuit-debugging support (with STLink v2 for example). Arduino can do this too but for some reason nobody does.

Target cost of unassembled pcb + components is 20 EURo's.
