Menelaos rev-4: common questions
What microcontroller does the Menelaos rev-4 use?
The Menelaos rev-4 is built around the STM32F103CBTx, from the STM32 family.
How big is the Menelaos rev-4 PCB?
The Menelaos rev-4 measures 99.5 × 91 mm, has 4 copper layers and is 1.59 mm thick.
How many components are on the Menelaos rev-4?
124 components, from 57 distinct parts. The full bill of materials is listed on this page.
Where can I download the Menelaos rev-4 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 rev-4 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 rev-4 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
