BlueMacro: common questions

What microcontroller does the BlueMacro use?

The BlueMacro is built around the Micro, from the AVR/Arduino family.

How big is the BlueMacro PCB?

The BlueMacro measures 20.3 × 48.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the BlueMacro?

29 components, from 26 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 BlueMacro design files?

From the jpconstantineau/NRF52-Board repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the BlueMacro design in my own project?

Yes, under the terms of its BSD-3-Clause license, which jpconstantineau chose for the repository.

Can I test firmware for the BlueMacro 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.
