UP1-GW-UART: common questions

What microcontroller does the UP1-GW-UART use?

The UP1-GW-UART is built around the RP2040, from the RP2040/RP2350 family.

How big is the UP1-GW-UART PCB?

The UP1-GW-UART measures 39 × 39 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UP1-GW-UART?

59 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the UP1-GW-UART design files?

From the OpenKNX/OpenKNX-UP1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the UP1-GW-UART design in my own project?

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

Can I test firmware for the UP1-GW-UART 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.
