About the MainBoard PCB

MainBoard is an open source STM32 PCB design by hughe349, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 120 × 135 mm, with 139 components from 56 distinct parts.

Its main chip is the STM32F091RCTx, from the STM32 family. Other key parts include the 968-CD22M3494MQZ, LM7321MAX/NOPB, TL071, AD5263BRUZ200 and XTPS55285VALR. By type, the board carries 38 ICs, 30 capacitors, 14 diodes, 13 connectors, 10 resistors and 4 fuses.

From the project

gaming

IRLTSPICE provides the convenience of spice with the accuracy and testability of a real-life analog circuit.

Simply design your circuit in your EDA tool of choice, or use our handy Python API, upload to the board, and bang! Your circuit now exists in real life, and you can now do whatever you want!

Run FRAs, send audio through it, use it as a testbed, or whatever else you can imagine. It's now just an analog circuit.

MainBoard: common questions

What microcontroller does the MainBoard use?

The MainBoard is built around the STM32F091RCTx, from the STM32 family.

How big is the MainBoard PCB?

The MainBoard measures 120 × 135 mm, has 4 copper layers and is 1.565 mm thick.

How many components are on the MainBoard?

139 components, from 56 distinct parts. The full bill of materials is listed on this page.

Where can I download the MainBoard design files?

From the hughe349/Senior_Design_IRLTSPICE repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MainBoard design in my own project?

Yes, under the terms of its GPL-3.0 license, which hughe349 chose for the repository.

Can I test firmware for the MainBoard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
