Design Details
Front Panel
- Glue on OLED with a couple of drops of Hot Glue in corners
- White on Black P Touch labels
- OLED - replace connector with 1x4 right angle connector
On Controls card
- Wire top pin of R7 to top pin of R17 (connects J5 to J6 tip)
- SW1 goes in cutout at J1
- SW1 up = DC coupled, down = AC coupled
- R7 stands up at bottom of R7 and wires to SW1 center
- 4.7uF cap from SW1 top to SW1 bottom
- + side of cap to SW1 bottom
- - side of cap to SW1 top
- Wire from J5 tip to SW1 bottom
On Daughterboard
CPU
- Arduino Pro Mini CPU
Pots connections
Jacks connections
