Converter: common questions
What microcontroller does the Converter use?
The Converter is built around the ESP32-C3-WROOM-02, from the ESP32 family.
How big is the Converter PCB?
The Converter measures 100 × 30 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Converter?
28 components, from 21 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 Converter design files?
From the himanshu40304/PCB_automation 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 Converter design in my own project?
The repository has no license, so all rights stay with himanshu40304. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Converter 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.
