Rebound: common questions

What microcontroller does the Rebound use?

The Rebound is built around the ESP32-S3, from the ESP32 family.

How big is the Rebound PCB?

The Rebound measures 41.8 × 49.6 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Rebound?

118 components, from 50 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 Rebound design files?

From the DynamicWhiteHat/Rebound 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 Rebound design in my own project?

The repository has no license, so all rights stay with DynamicWhiteHat. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Rebound 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.
