NugMacro-Keypad: common questions

What microcontroller does the NugMacro-Keypad use?

The NugMacro-Keypad is built around the ATMEGA32U4-A, from the AVR/Arduino family.

How big is the NugMacro-Keypad PCB?

The NugMacro-Keypad measures 76.2 × 95.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NugMacro-Keypad?

51 components, from 28 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 NugMacro-Keypad design files?

From the Sir-keet/NugMacro-Keypad 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 NugMacro-Keypad design in my own project?

Yes, under the terms of its MIT license, which Sir-keet chose for the repository.

Can I test firmware for the NugMacro-Keypad 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.
