A20 OLinuXino Lime2

A20 OLinuXino Lime2

Olimex's A20 OLinuXino Lime2 is a fully Open Source Hardware (OSHW) single board computer. This means that the designer is actively helping people using the platform for their own designs, and supports them in adding hardware functionality and production advice. This is a part of freedom that is often overlooked, but very much aligned with the FreedomBox goals. It uses the Allwinner A20 Dual Core ARM processor. FreedomBox images are built and tested for this device starting with version 0.7. To use this device as a FreedomBox, a separate USB WiFi device that does not require non-free firmware is recommended.

Recommendation: If you are using a board that uses SD cards, when you flash the FreedomBox image onto your SD card, we recommend that you use an SD card with at least 8GB of storage space.

1. Similar Hardware

The following similar hardware will also work well with FreedomBox.

2. Download

FreedomBox SD card images are available for this device. Follow the instructions on the download page to create a FreedomBox SD card and boot the device. These SD card images are meant for use with the on-board SD card slot and won't work when used with a separate SD card reader connected via USB.

An alternative to downloading these images is to install Debian on the device and then install FreedomBox on it.

3. Build Image

FreedomBox images for this hardware can be built using Freedom Maker.
