SPROJ3G2 PTX: common questions

What microcontroller does the SPROJ3G2 PTX use?

The SPROJ3G2 PTX is built around the RP2040, from the RP2040/RP2350 family.

How big is the SPROJ3G2 PTX PCB?

The SPROJ3G2 PTX measures 100 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SPROJ3G2 PTX?

47 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the SPROJ3G2 PTX design files?

From the boenike/SPROJ3G2_PTX_PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SPROJ3G2 PTX design in my own project?

Yes, under the terms of its GPL-3.0 license, which boenike chose for the repository.

Can I test firmware for the SPROJ3G2 PTX 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.
