EBoard remote control: common questions

What microcontroller does the EBoard remote control use?

The EBoard remote control is built around the MDBT42, from the Nordic nRF family.

How big is the EBoard remote control PCB?

The EBoard remote control measures 34 × 100 mm and is 1.6 mm thick.

How many components are on the EBoard remote control?

57 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the EBoard remote control design files?

From the kattemjau/MountainX-remote repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the EBoard remote control design in my own project?

Yes, under the terms of its MIT license, which kattemjau chose for the repository.

Can I test firmware for the EBoard remote control without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
