About the NANO HAT
NANO HAT is an open source AVR/Arduino PCB design by danielwilczak101, published on GitHub. It is a 2-layer board measuring 51.6 × 59.1 mm, with 16 components from 10 distinct parts.
Its main chip is the ARDUINO_NANO, from the AVR/Arduino family. Other key parts include the DMN4026SSD. By type, the board carries 7 connectors, 2 diodes, 2 capacitors, 2 resistors and 1 IC.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
Originally part of the NASA Asteroid flyer program has been repurposed by the EPPL to allow anyone interested in controls to go online and connect with a real working device and test their own control algorithms on a live device that is connected to the global internet.
Originally part of the NASA Asteroid flyer program has been repurposed by the EPPL to allow anyone interested in controls to go online and connect with a real working device and test their own control algorithms on a live device that is connected to the global internet. The spacecraft has been refitted with new and improved wiring, updated computers and a website that allows for members to connect and upload code to.

NANO HAT: common questions
What microcontroller does the NANO HAT use?
The NANO HAT is built around the ARDUINO_NANO, from the AVR/Arduino family.
How big is the NANO HAT?
The NANO HAT measures 51.6 × 59.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the NANO HAT?
16 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the NANO HAT design files?
From the danielwilczak101/EasyControls repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the NANO HAT design in my own project?
The repository has no license, so all rights stay with danielwilczak101. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the NANO HAT 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.
