Giant Board
An Open Source, Linux-capable SBC Compatible with the FeatherWing Ecosystem.
The Giant Board is a super tiny single-board computer (SBC) based on the Adafruit Feather form factor. We always want more power in a smaller package, and the Giant Board delivers! It provides a small, powerful platform that is compatible with a wide range of pre-existing accessories. FeatherWing support makes the Giant Board a flexible, drop-in component for most Feather based projects.
We all love our microcontrollers, but in some cases they just don’t have the resources we need to carry out the projects we have in mind. By squeezing the power of an SBC into a package the size of a microcontroller board, the Giant Board relaxes memory, storage, and processing constraints and allows you to take your projects to the next level.
Small, Light, & Powerful
The Giant Board fills the gap between microcontrollers and other single-board computers. It makes a great alternative to a Raspberry Pi or BeagleBone in a space constrained project where you need more power than a typical microcontroller can provide. The Giant Board is based on a form factor that is traditionally used for microcontrollers, so power consumption is important, which is why the Giant Board offers low-power modes.
A Versatile Miniature Single-Board Computer
To leverage all that powerful hardware, the Giant Board runs Linux. Not just any Linux, but full Debian Linux! This gives developers and users access to an endless number of applications and libraries for their projects.
The Giant Board could be used for projects related to:
- Media streaming
- IoT gateway routing
- Data collection & analysis
- Robotics
Adafruit Blinka (CircuitPython for Linux)
Adafruit has released a set of libraries that adds CircuitPython support to Linux. Considering that the Giant Board is a Feather that runs Linux…we saw taking advantage of this support as a no-brainer. Since then, Giant Board compatibility has been fully merged and committed to the Adafruit repo! As a result, the Giant Board now has access to over over 100 hardware compatibility libraries.
FeatherWing Support
The Giant Board supports the Adafruit FeatherWing pinout, which allows it to work with over 60 pre-existing add-on boards. And CircuitPython makes this easy to do. Most sample code works with little or no modification, so you can get your projects up and running more quickly.
One of the awesome things about running Linux on the Giant Board is that Linux provides drivers for many FeatherWings. Some examples that we have tested include the Ethernet, Wi-Fi, and LCD FeatherWings. You can use an Ethernet FeatherWing to give your Giant Board access to the Internet, for example, then take advantage of graphics libraries and frameworks outside of Arduino C++ and CircuitPython to visualize data about network traffic on an LCD FeatherWing.
We could not find a Linux compatible Wi-Fi FeatherWing, however, so we made one. It is based on the ATWILC1000 Wi-Fi chipset from Microchip and has a lot of great features.
