Front: common questions

What microcontroller does the Front use?

The Front is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Front PCB?

The Front measures 148 × 81 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Front?

7 components, from 6 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 Front design files?

From the Hack-a-Day/2025-Communicator_Badge 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 Front design in my own project?

Yes, under the terms of its MIT license, which Hack-a-Day chose for the repository.

Can I test firmware for the Front 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.
