Eurorack Prototyping card set
6 HP wide (30mm) front panel
3U tall
Three card set
- Board interconnect headers duplicated on headers
- 30mm wide front panel
- 28mm wide panel and daughtercards
6 POTS
- Marked as RV1-RV5
- Series resistors on pot wiper
- All 3 pot pins brought to top header
4 Jacks
- Marked as J1-J4
- Tip/sleeve brought to header near middle/bottom
Pots on top, jacks on bottom of card
- Easier to adjust pots without bumping into pots
- Pots more often accessed than jacks
Large prototyping area
- 58 nodes with 3 holes per node (29 per "side")
+12V, -12V down board edges
5V/GND down center of card
Bussed connections horizontally
Front Panel with generic labels
- Cover with White on Black P-Touch labels

J5 on the Controls card and J5 on the I/O card
Pot connections
- POTx-1 is fully CW connects to wiper
- POTx-2 is wiper
- POTX-3 is fully CCW connects to wiper

-The D107 is a very simple dual slew rate limiter. It can be used for portamento effects or to smooth out a stepped voltage from a sequencer, or for general audio or CV smoothing. Each channel contains a buffer with 100K input impedance suitable for pitch CVs. The slew pot affects the charging of a large capacitor connected to a second amplifier. The second amp provides buffering for output to isolate the output jack from the actual slewing function.
-Specifications:
-Dual slew rate limiter
-Control range of 0-10s (approx.)
-Power: +12V @ 5mA, -12V @ 5mA
