BastWiFi: common questions

What microcontroller does the BastWiFi use?

The BastWiFi is built around the ESP32-S2-WROVER, from the ESP32 family.

How big is the BastWiFi PCB?

The BastWiFi measures 60 × 22.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BastWiFi?

29 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the BastWiFi design files?

From the ElectronicCats/BastWiFi repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the BastWiFi design in my own project?

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

Can I test firmware for the BastWiFi 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.
