LIME2-SHIELD adds CAN, second SD-card, two UEXT connectors, Audio IN and OUT, breadboard friendly GPIOs to A20-OLinuXino-LIME2 Open Source Hardware Linux computer

A20-OLinuXino-LIME2 is with small compact design, this is why we couldn’t put on it all connectors for the functionality this board offers.

The existing 0.05″ step connectors are OK for cables and shields, but are pain when you want to breadboard something or to attach UEXT module.

This is why we made LIME2-SHIELD open source hardware shield. It has these signals available:

LIME2-SHIELD User manual explains how to prepare your SD-card for booting Linux on A20-OLinuXino-LIME2, then how to setup the board with different scripts and device tree.

Demo codes how to work with GPIO, I2C, SPI, CAN with C, Python and console are included:

    If the CANbus transceiver is connected to the same pins as with the A20-CAN OLIMEX Expansion board, can4linux should work out of the box.
