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.

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.
