EBadge: common questions

What microcontroller does the EBadge use?

The EBadge is built around the ESP32-C3-SuperMini, from the ESP32 family.

How big is the EBadge PCB?

The EBadge measures 40 × 66 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EBadge?

14 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the EBadge design files?

From the pointblank-club/EBadge repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the EBadge design in my own project?

Yes, under the terms of its Apache-2.0 license, which pointblank-club chose for the repository.

Can I test firmware for the EBadge 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.
