Mega: common questions
What microcontroller does the Mega use?
The Mega is built around the RP2350B, from the RP2040/RP2350 family.
How big is the Mega PCB?
The Mega measures 49.3 × 51.8 mm, has 4 copper layers and is 1.61668 mm thick.
How many components are on the Mega?
49 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mega design files?
From the 1vers1on/Mega repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Mega design in my own project?
The repository has no license, so all rights stay with 1vers1on. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Mega 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.
