About the SinglePhaseInverter PCB

SinglePhaseInverter is an open source STM32 PCB design by reljamar, published on GitHub under the MIT license. It is a 4-layer board measuring 190 × 91 mm, with 156 components from 32 distinct parts.

Its main chip is the NUCLEO-G431RB, from the STM32 family. Other key parts include the IR2113, LM1117MP-5.0/NOPB, LM393D, AD621 and INA122. By type, the board carries 65 resistors, 30 test points, 29 capacitors, 9 ICs, 7 diodes and 6 transistors.

From the project

A precursor project to a future three-phase inverter for driving synchronous motors

This folder contains the KiCAD project files for the first PCB version. There are four schematic pages: 1. Root page - top overview page. Displays how the individual sheets are connected, and contains some high-level elements such as mounting holes and input/output connectors; 2. Control page - contains the MCU and precharge control elements; 3. Power page - contains everything related to the high-power part of the inverter: the H-bridge, gate drivers, precharge relay, shunt resistors; 4. Measure page - contains all circuits used for measuring voltages and currents: voltage deviders…

SinglePhaseInverter: common questions

What microcontroller does the SinglePhaseInverter use?

The SinglePhaseInverter is built around the NUCLEO-G431RB, from the STM32 family.

How big is the SinglePhaseInverter PCB?

The SinglePhaseInverter measures 190 × 91 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the SinglePhaseInverter?

156 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the SinglePhaseInverter design files?

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

Can I use the SinglePhaseInverter design in my own project?

Yes, under the terms of its MIT license, which reljamar chose for the repository.

Can I test firmware for the SinglePhaseInverter 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.
