HALPI2-hardware: common questions
What microcontroller does the HALPI2-hardware use?
The HALPI2-hardware is built around the RP2040, from the RP2040/RP2350 family.
How big is the HALPI2-hardware PCB?
The HALPI2-hardware measures 187 × 109 mm, has 6 copper layers and is 1.5584 mm thick.
How many components are on the HALPI2-hardware?
541 components, from 184 distinct parts. The full bill of materials is listed on this page.
Where can I download the HALPI2-hardware design files?
From the hatlabs/HALPI2-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the HALPI2-hardware 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 HALPI2-hardware 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.
