Review on π» KNACRO 5V 2 Channel 10A PC USB Control Switch Relay Module: Intelligent Driver for Programmable Computer Control by Adam Nelson
work normally. good for power converter
works great. The current consumption is about 70 mA when one of the relays is switched on. Graphical user interface to control the operation of the board, but the user interface has a lot of room for improvement. I found a problem with my Dell computer. I think it is a USB1.1 device but Dell Optiplex 9020 does not support it. Keeps writing Unknown device. I need to connect this device through a USB2.0 hub as a workaround.
- delivery was very fast
- could have chosen a newer model
