From the project
A custom PCB for SlimeVR, with the intention of using the cheapest parts available in the smallest formfactor usable.

A utilitarian tracker design for SlimeVR, with the intention of using the cheapest parts available in the smallest form factor possible, while maintaining quality and usability.
NEW! Revision 2 motherboards have been added, removing the BMI160-QMC5883 IMU-Magnetometer combo, and replacing it with an LSM6DSR board which has a magnetometer built in. Technically, the LSM6DSR board is pin-compatible with the BMI160 (and therefore is compatible with the old rev 1…

Roachslimes motherboard: common questions
What microcontroller does the Roachslimes motherboard use?
The Roachslimes motherboard is built around the WeMos_D1_mini, from the ESP8266 family.
How big is the Roachslimes motherboard PCB?
The Roachslimes motherboard measures 34.5 × 49.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Roachslimes motherboard?
13 components, from 11 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 Roachslimes motherboard design files?
From the crazy-hair/roachslimes 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 Roachslimes motherboard design in my own project?
Yes, under the terms of its CC-BY-SA-4.0 license, which crazy-hair chose for the repository.
Can I test firmware for the Roachslimes motherboard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
