YMC-Mathpad: common questions
What microcontroller does the YMC-Mathpad use?
The YMC-Mathpad is built around the ESP32-C3FH4, from the ESP32 family.
How big is the YMC-Mathpad PCB?
The YMC-Mathpad measures 92 × 78 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the YMC-Mathpad?
73 components, from 40 distinct parts. The full bill of materials is listed on this page.
Where can I download the YMC-Mathpad design files?
From the mbayrao/YMC-Mathpad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the YMC-Mathpad design in my own project?
The repository has no license, so all rights stay with mbayrao. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the YMC-Mathpad 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.
