EPaper badge: common questions

What microcontroller does the EPaper badge use?

The EPaper badge is built around the RP2040, from the RP2040/RP2350 family.

How big is the EPaper badge PCB?

The EPaper badge measures 90 × 57 mm, has 2 copper layers and is 2.630198 mm thick.

How many components are on the EPaper badge?

54 components, from 27 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 badge design files?

From the krVishesh/ePaper_badge 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 EPaper badge design in my own project?

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

Can I test firmware for the EPaper badge without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
