UP1-SEN-8x: common questions
What microcontroller does the UP1-SEN-8x use?
The UP1-SEN-8x is built around the RP2040, from the RP2040/RP2350 family.
How big is the UP1-SEN-8x PCB?
The UP1-SEN-8x measures 39 × 39 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the UP1-SEN-8x?
61 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the UP1-SEN-8x 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-SEN-8x 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-SEN-8x 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.
