Its main chip is the STM32F072C8Ux, from the STM32 family. Other key parts include the USBLC6-4SC6, MIC5504-3.3YM5, SFH617A-1, 74LVC3G14 and 74LVC2G86. By type, the board carries 44 capacitors, 26 resistors, 11 ICs, 3 transistors, 3 diodes and 3 inductors.

From the project

PCB based Dual Resonance Solid State Tesla Coil Design

For documentation, please see (and like ;) my Hackaday project: https://hackaday.io/project/165112-pcbtc-gan-edition

For the mainboard, please use V1.6 to order the pcbs. Select the pcb thickness to be as thin as possible, eg. 1mm. For the current design you also need the bottom pcb coil (https://github.com/lucysrausch/pcbtc/tree/master/hardware/gerbercoil01) and the top pcb coil (https://github.com/lucysrausch/pcbtc/tree/master/hardware/gerbercoil04). For these pcbs, please use 1.6mm thickness or thicker (eg. 2mm).
