MokyaLora: common questions
What microcontroller does the MokyaLora use?
The MokyaLora is built around the SC1510-A4, from the RP2040/RP2350 family.
How big is the MokyaLora PCB?
The MokyaLora measures 66 × 105 mm, has 6 copper layers and is 1.9524 mm thick.
How many components are on the MokyaLora?
328 components, from 97 distinct parts. The full bill of materials is listed on this page.
Where can I download the MokyaLora design files?
From the tengigabytes/MokyaLora repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the MokyaLora design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the MokyaLora 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.
