I've designed a new controller modules with a single rotary encoder with switch. I've replaced the old "double rotary" controllers with the newer "single rotary" controllers to improve modularity and for easier replacement when a rotary breaks.
It may be easy to integrate in any enclosure / front panel and could be used for mounting Zynthian Boxes with more than 4 controllers, or, e.g., to build an external controller with Arduino
It has the possibility of soldering 3 capacitors, one for each GPIO input (2 for the encoder and 1 for the switch). Currently, i'm only using the switch capacitor (100nF) because the rotary speed is limited when adding the other 2. I've to test with smaller capacitors.
Some of you have ask me for buying some PCBs, so here is the price list:
- 1-5 => 4€
- 5-20 => 3€
- 20-100 => 2€
- more? => better you order in a PCB factory
Of course, shipping is not included, but should be very cheap.
