Esp-Sumo: common questions
What microcontroller does the Esp-Sumo use?
The Esp-Sumo is built around the C2913202, from the ESP32 family.
How big is the Esp-Sumo PCB?
The Esp-Sumo measures 175.2 × 64.7 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Esp-Sumo?
84 components, from 46 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 Esp-Sumo design files?
From the Dunbarin-O/Esp-Sumo 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 Esp-Sumo design in my own project?
The repository has no license, so all rights stay with Dunbarin-O. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp-Sumo 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.
