About the DRSSTC-Fiber-Optic-Interrupter PCB

DRSSTC-Fiber-Optic-Interrupter is an open source STM32 PCB design by Alberto0235, published on GitHub under the MIT license. It is a 4-layer board measuring 150 × 100 mm, with 197 components from 57 distinct parts.

Its main chip is the STM32F405VGT6, from the STM32 family. Other key parts include the BQ29700DSER, USBLC6-2SC6, BQ24075RGTR, CSD16406Q3 and TLV62569DBVR. By type, the board carries 79 resistors, 58 capacitors, 14 test points, 9 ICs, 9 switches and 9 diodes.

It belongs with the power & battery designs in this gallery.

From the project

Custom 4-layer interrupter control board for DRSSTC systems. STM32F405-based, fiber-optically isolated outputs, hardware E-brake safety chain, and controlled-impedance routing (90Ω USB, 50Ω FSMC/SDIO). Designed in KiCad 9.0.

This repository contains the hardware design for a custom interrupter control board built for a Dual Resonant Solid State Tesla Coil (DRSSTC).

While the high-power driver is the "brain" of the system, the interrupter plays a fundamental role: it generates the PWM signal that is sent to the driver, which in turn generates the gate drive pulses to modulate the Tesla Coil's output.
