About the Encoderboard PCB

Encoderboard is an open source STM32 PCB design by SSL-A-Team, published on GitHub under the MIT license. It is a 2-layer board measuring 64 × 10 mm, with 8 components from 8 distinct parts.

Its main chip is the STM32H723ZGTX, from the STM32 family. By type, the board carries 3 resistors, 2 connectors, 2 capacitors and 1 IC.

From the project

circuit board design files, gerbers, and circuit analysis

All current board releases use KiCad 7.X.

See releases for competition production files. Our releases include known bug documentation, and the confirmed gerber, BoM, and CPL files sent to fab so you know you're looking and ordering what we did. Releases are accompanied by a tagged commit, for all editable project files used to generate the fab products.

For complex boards like control and kicker, we include spice models and python files that compute any relevant values from datasheets, and including documented references and links to needed formulations.

Encoderboard: common questions

What microcontroller does the Encoderboard use?

The Encoderboard is built around the STM32H723ZGTX, from the STM32 family.

How big is the Encoderboard PCB?

The Encoderboard measures 64 × 10 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Encoderboard?

8 components, from 8 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Encoderboard design files?

From the SSL-A-Team/electrical repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Encoderboard design in my own project?

Yes, under the terms of its MIT license, which SSL-A-Team chose for the repository.

Can I test firmware for the Encoderboard 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.
