Ec: common questions

What microcontroller does the Ec use?

The Ec is built around the XIAO_nRF52840_plus_mki, from the Nordic nRF family.

How big is the Ec PCB?

The Ec measures 139.2 × 111.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ec?

30 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ec design files?

From the Diwamoto/sage60 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ec design in my own project?

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

Can I test firmware for the Ec 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.
