About the Sympetrum v2 NFF1.1 PCB

Sympetrum v2 NFF1.1 is an open source STM32 PCB design by borgel, published on GitHub under the MIT license. It is a board measuring 40 × 80 mm, with 49 components from 33 distinct parts.

Its main chip is the STM32F030K6T6, from the STM32 family. Other key parts include the TSSP58P38, APA102_2020 and AAT1217ICA-3.3-T1. By type, the board carries 14 capacitors, 13 ICs, 8 resistors, 3 connectors, 3 switches and 3 diodes.

It belongs with the wearables designs in this gallery.

From the project

A communicative piece of wearable electronics.

If you'd rather do things the hard way you can directly upload the BOM to Digikey or a tool like Octopart which will make it easy to order from a variety of suppliers.

To recompile the firmware for this CPU edit the Makefile and swap the CPU variable by commenting out the line for STM32F030x6 and in the one for STM32F051x8.

The firmware is "version 4" and is tagged as a release on GitHub (and in the Firmware directory).
