Heizung Pünterswis: common questions

What microcontroller does the Heizung Pünterswis use?

The Heizung Pünterswis is built around the RP2040, from the RP2040/RP2350 family.

How big is the Heizung Pünterswis PCB?

The Heizung Pünterswis measures 100 × 160 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Heizung Pünterswis?

57 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Heizung Pünterswis design files?

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

Can I use the Heizung Pünterswis design in my own project?

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

Can I test firmware for the Heizung Pünterswis 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.
