TEL432 Project: common questions

What microcontroller does the TEL432 Project use?

The TEL432 Project is built around the RP2350B, from the RP2040/RP2350 family.

How big is the TEL432 Project PCB?

The TEL432 Project measures 110 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TEL432 Project?

41 components, from 34 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 TEL432 Project design files?

From the ceugbo/PCB-Designs 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 TEL432 Project design in my own project?

The repository has no license, so all rights stay with ceugbo. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TEL432 Project 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.
