Usbc car module: common questions
What microcontroller does the Usbc car module use?
The Usbc car module is built around the ESP32-S2FH2, from the ESP32 family.
How big is the Usbc car module?
The Usbc car module measures 283 × 159.2 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the Usbc car module?
350 components, from 89 distinct parts. The full bill of materials is listed on this page.
Where can I download the Usbc car module design files?
From the mickdassive/usbc_car_module repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Usbc car module design in my own project?
Yes, under the terms of its GPL-3.0 license, which mickdassive chose for the repository.
Can I test firmware for the Usbc car module 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.
