About the R2d2 PCB

R2d2 is an open source ESP32 PCB design by JoelBiswas, published on GitHub. It is a board, with 8 components from 5 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the Pololu_Breakout_A4988. By type, the board carries 5 ICs, 1 module and 1 capacitor.

It belongs with the robotics & motion designs in this gallery.

From the project

R2D2 robot from Star Wars that can move around and rotate its head. Designed to be 3D printed. Uses an ESP32 as the primary processor.

R2d2: common questions

What microcontroller does the R2d2 use?

The R2d2 is built around the ESP32-WROOM-32, from the ESP32 family.

How many components are on the R2d2?

8 components, from 5 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 R2d2 design files?

From the JoelBiswas/r2d2 repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the R2d2 design in my own project?

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

Can I test firmware for the R2d2 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.
