About the GNBoard (Shield for Arduino Mega)

GNBoard (Shield for Arduino Mega) is an open source AVR/Arduino PCB design by CarlosGS, published on GitHub. It is a board measuring 80.8 × 55.4 mm, with 56 components from 43 distinct parts.

Its main chip is the ARDUINO_MEGA_SHIELD, from the AVR/Arduino family. By type, the board carries 18 resistors, 13 relays, 11 connectors, 5 capacitors, 3 switches and 1 transistor.

It belongs with the robotics & motion, sensors and dev boards & breakouts designs in this gallery.

From the project

A 3D-printable robotic platform for testing swarm algorithms

An efficient solution for powering mobile robots. The GNBoard can also incorporate a ZigBee-compatible module and many other multimodal sensors (a gas detector for odor sensing, an accelerometer/electronic compass, temperature and humidity sensors, luminosity sensors), and multiple kinds of actuators as well (servomotors, a speaker, LEDs, etc).

The motion of the robot is achieved using two continuous rotation servomotors (SM-S4303R) as the main actuators. Servomotors provide a compact and low-cost solution to achieve the digital speed control needed. The main downside of this kind of…

GNBoard (Shield for Arduino Mega): common questions

What microcontroller does the GNBoard (Shield for Arduino Mega) use?

The GNBoard (Shield for Arduino Mega) is built around the ARDUINO_MEGA_SHIELD, from the AVR/Arduino family.

How big is the GNBoard (Shield for Arduino Mega)?

The GNBoard (Shield for Arduino Mega) measures 80.8 × 55.4 mm and is 1.6 mm thick.

How many components are on the GNBoard (Shield for Arduino Mega)?

56 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the GNBoard (Shield for Arduino Mega) design files?

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

Can I use the GNBoard (Shield for Arduino Mega) design in my own project?

The repository has no license, so all rights stay with CarlosGS. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the GNBoard (Shield for Arduino 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.
