Msxnano dock: common questions

What microcontroller does the Msxnano dock use?

The Msxnano dock is built around the ESP32-C6-WROOM-1-N8, from the ESP32 family.

How big is the Msxnano dock PCB?

The Msxnano dock measures 120 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Msxnano dock?

85 components, from 47 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 Msxnano dock design files?

From the Papipapito/MSXnano-Boards 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 Msxnano dock design in my own project?

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

Can I test firmware for the Msxnano dock 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.
