50: common questions

What microcontroller does the 50 use?

The 50 is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.

How big is the 50 PCB?

The 50 measures 71.5 × 51.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 50?

17 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the 50 design files?

From the mohit716/esp32-c3-usbc-tft-controller repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the 50 design in my own project?

The repository has no license, so all rights stay with mohit716. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 50 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.
