I designed this PC board to add “GENERIC” analog inputs,
for EIGHT joysticks, volume controls, positioners or brightness…
whatever you want! Wirelessly! Using CAYENNE!

Parts cost about $20 + shipping (Pi Zero and wall wart not included)
PC board blanks cost $9 + shipping on eBay (by request)
It sports a Pi Zero footprint
-but will work perfectly with any Pi GPIO header.
You can flush mount directly over a Pi Zero using .1" header pins.
On-board voltage regulator accepts voltages from +7.5V to +24V,
provides power to the Pi, -so you don’t need the Pis’ finniky P/S-
The pots can be anything from 1K to 100K,
(you set your own impedance)
Each of the eight .1" header pin X 3 sets provide
+3v3
Analog In
Gnd(-)
Everything you need for a pot- 3 wires!
Cayenne already has the extention for
the Pi using the MCP3008 AND the MCP3208 chip.
