Wiring – Stage 1

Connecting the EchoTapper Universal Interface shield (designed by Piet Verbruggen) to the Eccamatic Valve eTap2hw pcb (designed by Eric Thacker aka ‘ecca’).

The blue (Pot0), violet (Pot1) and grey (Pot 2) wires send the control voltages from the Arduino to the SKRM module (not yet mounted) on ecca’s board. The brown (+3.3V), red (SW0) , orange (SW1) and yellow (SW2) wires send the echo model select signals to the SKRM, replicating the action of the original BCD switch in the manual eTap2hw.

The rotary encoder, the push switches and the input jack socket are also wired on the front panel. The next stage is to wire up the front panel pots and the ‘peak’ LED.ImageImage
