Universal-Taster: common questions
What microcontroller does the Universal-Taster use?
The Universal-Taster is built around the EFM32PG12B500, from the Silicon Labs family.
How big is the Universal-Taster PCB?
The Universal-Taster measures 30 × 30 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Universal-Taster?
55 components, from 30 distinct parts. The full bill of materials is listed on this page.
Where can I download the Universal-Taster design files?
From the basilfx/KNX-Universal-Taster repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Universal-Taster 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 Universal-Taster without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Silicon Labs firmware against it before you order a PCB.
