Esp32-pcb bitraf: common questions

What microcontroller does the Esp32-pcb bitraf use?

The Esp32-pcb bitraf is built around the ESP32-S2-M, from the ESP32 family.

How big is the Esp32-pcb bitraf?

The Esp32-pcb bitraf measures 25.4 × 55.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-pcb bitraf?

23 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-pcb bitraf design files?

From the blurpy/esp32-pcb-bitraf repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32-pcb bitraf design in my own project?

Yes, under the terms of its MIT license, which blurpy chose for the repository.

Can I test firmware for the Esp32-pcb bitraf 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.
