For those of you, who don’t want to use 2x8 encoders at a time, here is the first design of a PCB I made. There are a few things to improve, but it’s working!
In the next days I will equip another PCB with the parts and see, if the forwarding is working and if there is enough space for all the connectors / connections.
For now the LEDs are driven by the 74H595 only and each LED is feeded with 15mA. I think, for later use they are not bright enough. I don’t think, things will change, if I use a ULN2803 for driving the LEDs, because the difference in brightness between 15mA or 20mA is really not that much. Maybe I should use other LEDs…
Hello FantomXR,
there is also available a single pcb with 8 rotary encoders each with leds ring and 1 , 2 or 3 switches “place” as well + cascade connection option
for get a single or more lines with 8,16,24,32…. rotary encoders connected in cascade mode ?
thanks
