Oshwi ESP32: common questions
What microcontroller does the Oshwi ESP32 use?
The Oshwi ESP32 is built around the ESP32-WROOM-32D, from the ESP32 family.
How big is the Oshwi ESP32 PCB?
The Oshwi ESP32 measures 83.9 × 108.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Oshwi ESP32?
21 components, from 21 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 Oshwi ESP32 design files?
From the hulkco/oshwi repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Oshwi ESP32 design in my own project?
The repository has no license, so all rights stay with hulkco. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Oshwi ESP32 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.
