About the NRF servo Mega PCB

NRF servo Mega is an open source AVR/Arduino PCB design by michaelshiloh, published on GitHub under the AGPL-3.0 license. It is a 2-layer board measuring 85.1 × 53.3 mm, with 12 components from 7 distinct parts.

Its main chip is the Arduino_Mega2560_Shield, from the AVR/Arduino family. Other key parts include the NRF24L01_Breakout. By type, the board carries 5 diodes, 3 capacitors, 1 IC, 1 module and 1 connector.

It belongs with the robotics & motion designs in this gallery.

From the project

This shield is mean to sit on a Mega (which means using the SPI pins on the ICSP header) with the Adafruit Music Maker Shield.

NRF servo Mega: common questions

What microcontroller does the NRF servo Mega use?

The NRF servo Mega is built around the Arduino_Mega2560_Shield, from the AVR/Arduino family.

How big is the NRF servo Mega PCB?

The NRF servo Mega measures 85.1 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NRF servo Mega?

12 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the NRF servo Mega design files?

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

Can I use the NRF servo Mega design in my own project?

Yes, under the terms of its AGPL-3.0 license, which michaelshiloh chose for the repository.

Can I test firmware for the NRF servo Mega 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.
