About the SlimeVR-Tracker-ESP-Hardware PCB

SlimeVR-Tracker-ESP-Hardware is an open source ESP32 PCB design by HelaFaye, published on GitHub under the Apache-2.0 license. It is a board, with 33 components from 23 distinct parts.

Its main chip is the ESP32-C5-WROOM-1, from the ESP32 family. Other key parts include the ICM-45686, QMC6309, AP2112K-3.3 and MCP73831. By type, the board carries 17 resistors, 5 ICs, 5 capacitors, 3 connectors, 2 diodes and 1 switch.

From the project

Hardware for I2SPI, which carries several SlimeVR IMUs on one RJ45 cable: an ESP32-C5 hub board and ATtiny412 sensor-node boards.

Hardware for I2SPI, which carries several SlimeVR IMUs on one RJ45 cable: an ESP32-C5 hub board and ATtiny412 sensor-node boards.

The wire protocol and cable pinout are defined in the firmware repo. When changing a net here that crosses the RJ45, change it there too.

Board specifications: docs/BOARD-SPECS.md. Checks: ./verify.sh.

Generates KiCad projects, a JLCPCB BOM and a V-scored panel configuration for the two I2SPI boards.

The KiCad project lives in the HelaFaye/SlimeVR-Tracker-ESP-Hardware repository on GitHub; these links point at the commit this page was built from.

SlimeVR-Tracker-ESP-Hardware: common questions

What microcontroller does the SlimeVR-Tracker-ESP-Hardware use?

The SlimeVR-Tracker-ESP-Hardware is built around the ESP32-C5-WROOM-1, from the ESP32 family.

How many components are on the SlimeVR-Tracker-ESP-Hardware?

33 components, from 23 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 SlimeVR-Tracker-ESP-Hardware design files?

From the HelaFaye/SlimeVR-Tracker-ESP-Hardware repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the SlimeVR-Tracker-ESP-Hardware design in my own project?

Yes, under the terms of its Apache-2.0 license, which HelaFaye chose for the repository.

Can I test firmware for the SlimeVR-Tracker-ESP-Hardware without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
