REG1-IpController2040: common questions

What microcontroller does the REG1-IpController2040 use?

The REG1-IpController2040 is built around the RP2040, from the RP2040/RP2350 family.

How big is the REG1-IpController2040 PCB?

The REG1-IpController2040 measures 83.2 × 15.7 mm, has 4 copper layers and is 1 mm thick.

How many components are on the REG1-IpController2040?

86 components, from 45 distinct parts. The full bill of materials is listed on this page.

Where can I download the REG1-IpController2040 design files?

From the OpenKNX/OpenKNX-REG1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the REG1-IpController2040 design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the REG1-IpController2040 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.
