Nothing wrong with them as I just upgraded to a bigger board setup. AlphaPix Classic 16 V3 – E1.31 & ArtNet to SPI Pixel Controller w/LCD Display – 16 SPI + 3 RS485 Outputs – Bought this controller last year. AlphaPix Classic 4 V3 – E1.31 & ArtNet to SPI Pixel Controller w/LCD Display – 4 SPI + 1 RS485 Outputs – Bought this controller 2years ago.
