Remora design files

The KiCad project lives in the alexthomazo/remora repository on GitHub; these links point at the commit this page was built from.

Remora: common questions

What microcontroller does the Remora use?

The Remora is built around the ESP32-D1-MINI, from the ESP32 family.

How big is the Remora PCB?

The Remora measures 66 × 86 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Remora?

105 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the Remora design files?

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

Can I use the Remora design in my own project?

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

Can I test firmware for the Remora 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.
