IR ring v05: common questions

What microcontroller does the IR ring v05 use?

The IR ring v05 is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the IR ring v05 PCB?

The IR ring v05 measures 81.3 × 81.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IR ring v05?

25 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the IR ring v05 design files?

From the bohlebots/soccer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the IR ring v05 design in my own project?

Yes, under the terms of its GPL-2.0 license, which bohlebots chose for the repository.

Can I test firmware for the IR ring v05 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.
