6s4in1 4layer: common questions
What microcontroller does the 6s4in1 4layer use?
The 6s4in1 4layer is built around the EFM8BB21-QFN20, from the Silicon Labs family.
How big is the 6s4in1 4layer PCB?
The 6s4in1 4layer measures 22.6 × 20 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the 6s4in1 4layer?
154 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the 6s4in1 4layer design files?
From the lucascheuer/6s4in1_4layer repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the 6s4in1 4layer design in my own project?
Yes, under the terms of its GPL-3.0 license, which lucascheuer chose for the repository.
Can I test firmware for the 6s4in1 4layer 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.
