Main board: common questions
What microcontroller does the Main board use?
The Main board is built around the Stamp_Pico, from the RP2040/RP2350 family.
How big is the Main board?
The Main board measures 110 × 110 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Main board?
35 components, from 19 distinct parts. The full bill of materials is listed on this page.
Where can I download the Main board design files?
From the MUNAKATA-EPC/Amateras repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Main board design in my own project?
The repository has no license, so all rights stay with MUNAKATA-EPC. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Main board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
