Developers, makers and electronics enthusiasts searching for a miniature open source development board may be interested to know that the Tomu is now available from the online Adafruit store. Equipped with a Gecko EFM32HG309 processor the small form factor allows the small development board to start directly into your computers USB A port.
The Tomu is equipped with a native USB bootloader, two tiny LEDs and two capacitive-touch pads. Originally designed for 2-factor authentication, it’s great for very tiny USB projects, ARM/Gecko experimentation or adding a basic input to your computer and its fully open source.
The miniature open source development board is now available to purchase directly from the Adafruit online store priced at $27.50. Measuring just 13 mm long x 10mm x 1.5mm the Tomu offers a speed of 25 MHz ARM Cortex-M0+, 8K RAM and 64KB of Flash storage and is supplied fully assembled.
“The PCB is thinner than a USB socket, and has exposed contacts on the reverse side, so it /needs a case/ in order to make proper contact with the USB pins, and to not short on the shield of the USB port. Early prototypes used a business card that had been folded over, however the crowd funding campaign made enough to cut steel and make a case.”
