Menelaos v2: common questions

What microcontroller does the Menelaos v2 use?

The Menelaos v2 is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the Menelaos v2 PCB?

The Menelaos v2 measures 99.5 × 81 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Menelaos v2?

82 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Menelaos v2 design files?

From the acastles91/menelaos repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Menelaos v2 design in my own project?

The repository has no license, so all rights stay with acastles91. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Menelaos v2 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.
