SUMEC MK IV: common questions

What microcontroller does the SUMEC MK IV use?

The SUMEC MK IV is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the SUMEC MK IV PCB?

The SUMEC MK IV measures 80 × 45 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the SUMEC MK IV?

84 components, from 42 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 SUMEC MK IV design files?

From the bismarx-v1/Sumec-MiniSumo 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 SUMEC MK IV design in my own project?

The repository has no license, so all rights stay with bismarx-v1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SUMEC MK IV 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.
