Mercury2020: common questions

What microcontroller does the Mercury2020 use?

The Mercury2020 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Mercury2020 PCB?

The Mercury2020 measures 99.1 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mercury2020?

37 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mercury2020 design files?

From the ksurct/mercury2020 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mercury2020 design in my own project?

Yes, under the terms of its Apache-2.0 license, which ksurct chose for the repository.

Can I test firmware for the Mercury2020 without the hardware?

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