A really handy and unique board. Controls multiple (3) DMX universes with ease via the SPI bus of your microcontroller while freeing up processing/timing from your microcontroller as well. Am using two of these boards for 4 universes. Great communication and support from the seller also - many thanks!
The shield was super easy to install on my Arduino Leonardo ETH. The provided documentation is very good and I could use the shield with only a few changes on my Arduino (I documented the changes here: https://github.com/NERDDISCO/VisionLord). My DMX universe is controllable like with every other DMX controller. The quality is also super good. I'm very satisfied and I'm looking forward to buy more shields in the future.
The shield works well and has a very solid build with two XLR plugs of good quality. The library is also very simple to use. Note: To not switch the onboard jumper back and forth between programming and testing it's possible to use two IO pins instead of RX/TX, the manufacturer also suggested to eventually use an Arduino Leonardo…
