About the Dual Axis Controller PCB

Dual Axis Controller is an open source STM32 PCB design by jrseti, published on GitHub under the CC0-1.0 license. It is a 4-layer board measuring 140 × 100 mm, with 307 components from 114 distinct parts.

Its main chip is the STM32G474RET6, from the STM32 family. Other key parts include the LTC4311ISC6#TRPBF, LM75BIMX-3/NOPB, W25Q32JVSSIQ, MAX-M10S-00B and MP2322GQH-Z. By type, the board carries 98 resistors, 92 capacitors, 40 diodes, 17 ICs, 15 connectors and 8 test points.

It belongs with the rf & radio designs in this gallery.

From the project

Simple controller with toggle switches to move the dish motors

A satellite dish motion controller with an on-board Raspberry Pi Compute Module 4.

This board carries the CM4 as the local host for the STM32-based two-axis motion controller, replacing the external PC/Pi that previously commanded the design over a long RS485 run.

Derived from the Axis Commander (jrdishaxiscontroller).

The Axis Commander's own history stays in the pcbs monorepo; this repo starts fresh rather than importing it. The baseline includes commit 9e2432b, which corrected the encoder input RC values that caused missed ticks at speed on V1.1.

Dual Axis Controller: common questions

What microcontroller does the Dual Axis Controller use?

The Dual Axis Controller is built around the STM32G474RET6, from the STM32 family.

How big is the Dual Axis Controller PCB?

The Dual Axis Controller measures 140 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Dual Axis Controller?

307 components, from 114 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dual Axis Controller design files?

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

Can I use the Dual Axis Controller design in my own project?

Yes, under the terms of its CC0-1.0 license, which jrseti chose for the repository.

Can I test firmware for the Dual Axis Controller 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.
