I’ve got Orange Pi SBC and found fork of LED-matrix library at [GitHub - mrfaptastic/opi-allwinner-h3-rgb-led-matrix: Controlling one chain of 64x64, 32x32, 16x32 or similar RGB LED displays using Orange Pi (Allwinner H3) GPIO](https://github.com/mrfaptastic/opi-allwinner-h3-rgb-led-matrix) which support only one chain. But original Henner Zeller’s library support 3 channel running on RPi. My question is what is limitation of Orange Pi with suggested PCB adapter (active, 3-chain)? Why only one chain is supported?

If your orangepi has all the IO pins of a regular rPi, you should simply use the active-3 board and this library to get 3 chains in parallel.  
Have you verified that this lib does not work on OrangePi?
