MaSe
About the MaSe PCB
MaSe is an open source ESP32 PCB design by mornepousse, published on GitHub. It is a 2-layer board measuring 63.8 × 97.6 mm, with 36 components from 25 distinct parts.
Its main chip is the W25Q128JVS, from the ESP32 family. Other key parts include the TCR2EF19, PMW3360, RP2040, TLV73333PDBV and AP130-33SA. By type, the board carries 10 switches, 7 ICs, 7 capacitors, 5 resistors, 4 connectors and 2 transistors.

MaSe: common questions
What microcontroller does the MaSe use?
The MaSe is built around the W25Q128JVS, from the ESP32 family.
How big is the MaSe PCB?
The MaSe measures 63.8 × 97.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MaSe?
36 components, from 25 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 MaSe design files?
From the mornepousse/Mase 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 MaSe design in my own project?
The repository has no license, so all rights stay with mornepousse. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MaSe 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.
