The board was originally designed by the company Aquatron which I can't find anymore online. It has the Markings JS2A and RS2-1UE on it. Some of the original controllers started failing, so I designed a replacement board. It offers the same IN and OUT connections and has more or less the same functionality.
You can connect boards together to control more shutters. This can be achieved with the Single-IN and Multi-IN connectors to be able to still control the blind separately. If you press the shutter for more that 2 seconds, it will drive to the end position for 180 seconds. This can be stopped by pressing the opposing direction button.
There is an additional fuse compared to the JS2A, this is to protect the 5V logic and should only be replaced with a T500mA 5x20mm fuse. The other one is a T4A 5x20mm and protects mainly the window shade motors.
There is an ATmega328p with the Arduino bootloader on board that can be reprogrammed on any Arduino Uno board. The micro-controller used by Aquatron had its markings filed off. The last picture in the gallery is a photo I took from the original controller so you can compare them. It is not the one I designed and not for sale.
ATTENTION: Please don't mix old and new boards in a sequence, the new one runs on 5VDC. Please note that this is board is not CE certified and is not approved to be built in or used somewhere other than a test setup on your bench.
