SEWCS Commercial v1: common questions
What microcontroller does the SEWCS Commercial v1 use?
The SEWCS Commercial v1 is built around the ESP32-WROOM-32E, from the ESP32 family.
How big is the SEWCS Commercial v1 PCB?
The SEWCS Commercial v1 measures 115 × 80 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the SEWCS Commercial v1?
50 components, from 29 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 SEWCS Commercial v1 design files?
From the Aru123321/KiCad 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 SEWCS Commercial v1 design in my own project?
