Alpha hs: common questions

What microcontroller does the Alpha hs use?

The Alpha hs is built around the RP2040, from the RP2040/RP2350 family.

How big is the Alpha hs PCB?

The Alpha hs measures 190.5 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Alpha hs?

111 components, from 21 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 Alpha hs design files?

From the onisage/megacorp-main 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 Alpha hs design in my own project?

Yes, under the terms of its MIT license, which onisage chose for the repository.

Can I test firmware for the Alpha hs 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.
