EduSpectro4X: common questions

What microcontroller does the EduSpectro4X use?

The EduSpectro4X is built around the RP2350-Zero, from the RP2040/RP2350 family.

How big is the EduSpectro4X PCB?

The EduSpectro4X measures 57 × 47 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EduSpectro4X?

13 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the EduSpectro4X design files?

From the EduSpectro/EduSpectro4X repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the EduSpectro4X design in my own project?

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

Can I test firmware for the EduSpectro4X 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.
