Epaper breakout: common questions

What microcontroller does the Epaper breakout use?

The Epaper breakout is built around the ESP32-WROVER, from the ESP32 family.

How big is the Epaper breakout?

The Epaper breakout measures 100 × 45 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Epaper breakout?

98 components, from 47 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 Epaper breakout design files?

From the jifanchn/micropython-papers3m5 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Epaper breakout design in my own project?

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

Can I test firmware for the Epaper breakout 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.
