About the Medora PCB

Medora is an open source ESP32 PCB design by pizzalover125, published on GitHub. It is a 2-layer board measuring 190 × 90 mm, with 9 components from 2 distinct parts.

Its main chip is the XIAO ESP32C3, from the ESP32 family. By type, the board carries 8 diodes and 1 IC.

From the project

a project that saves lives

Medication nonadherence contributes to roughly 125,000 deaths every year in the U.S. (Kim and Sarah A.) Pill organizer users saw adherence rise from 65% to as high as 100% within months (Rathod et al.) * Patients using a smart pill organizer were 60% more compliant than those without one, nearly double the 32% improvement seen with a standard pillbox (Godin)

Medora: common questions

What microcontroller does the Medora use?

The Medora is built around the XIAO ESP32C3, from the ESP32 family.

How big is the Medora PCB?

The Medora measures 190 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Medora?

9 components, from 2 distinct parts. The full bill of materials is listed on this page.

Where can I download the Medora design files?

From the pizzalover125/medora repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Medora design in my own project?

The repository has no license, so all rights stay with pizzalover125. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Medora 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.
