What boards using the R are built for

R: common questions

Where can I find a R reference design?

Each of the 3 boards on this page is a real design using the R. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.

Which microcontrollers do boards using the R use?

Most are built on ESP32 (1).

How big is a typical board using the R?

The median is 20 × 54 mm, and 67% are two-layer designs.

What is the most popular open source board using the R?

By GitHub stars, Esp32-drone flight controller by Prateek-elec, with 0 stars.

Can I simulate one of these boards using the R before building it?

Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
