92pi: common questions
What microcontroller does the 92pi use?
The 92pi is built around the RP2040, from the RP2040/RP2350 family.
How big is the 92pi PCB?
The 92pi measures 201.7 × 112.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 92pi?
220 components, from 117 distinct parts. The full bill of materials is listed on this page.
Where can I download the 92pi design files?
From the hexmaster111/92pi repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the 92pi design in my own project?
The repository has no license, so all rights stay with hexmaster111. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the 92pi 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.
