LASK5 V2-0: common questions

What microcontroller does the LASK5 V2-0 use?

The LASK5 V2-0 is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the LASK5 V2-0 PCB?

The LASK5 V2-0 measures 75 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LASK5 V2-0?

43 components, from 25 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the LASK5 V2-0 design files?

From the Open-Muscle/OpenMuscle-LASK5 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the LASK5 V2-0 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which Open-Muscle chose for the repository.

Can I test firmware for the LASK5 V2-0 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
