Motorcycle telemetry unit: common questions

What microcontroller does the Motorcycle telemetry unit use?

The Motorcycle telemetry unit is built around the ESP32-S2-WROVER, from the ESP32 family.

How big is the Motorcycle telemetry unit PCB?

The Motorcycle telemetry unit measures 133.8 × 95.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Motorcycle telemetry unit?

109 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the Motorcycle telemetry unit design files?

From the Data-ptr/Motorcycle-telemetry-unit repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Motorcycle telemetry unit design in my own project?

Yes, under the terms of its Unlicense license, which Data-ptr chose for the repository.

Can I test firmware for the Motorcycle telemetry unit 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.
