ESP32-bat monitor latch: common questions

What microcontroller does the ESP32-bat monitor latch use?

The ESP32-bat monitor latch is built around the ES-WROOM-32, from the ESP32 family.

How big is the ESP32-bat monitor latch PCB?

The ESP32-bat monitor latch measures 33 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-bat monitor latch?

29 components, from 12 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 ESP32-bat monitor latch design files?

From the pcbreflux/espressif repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ESP32-bat monitor latch design in my own project?

Yes, under the terms of its GPL-3.0 license, which pcbreflux chose for the repository.

Can I test firmware for the ESP32-bat monitor latch 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.
