ER-PROTO-02 SET P1080833-720pxV.jpg

Features

  • Eurorack Prototyping 3 card set
    • Front panel card
    • Controls
    • Prototyping daughtercard
  • 6 HP wide (30mm) front panel
  • Controls and prototyping cards are 28mm wide
  • 3U tall
  • Pots on top, jacks on bottom
    • Easier to adjust pots without bumping into pots
    • Pots are more often accessed than jacks
  • 0-6 POTS
    • Series resistors on pot wiper on controls card
    • All 3 pot pins brought to top header
    • Jumpers on control card allow GND/VCC to be set on pot ends
  • 0-6 "Thinkicon style" Jacks
    • Can use stereo or mono jacks
    • Tip/ring brought to header near bottom
  • Large prototyping area
  • Power/GND down center of card
  • Bussed connections horizontally
  • Front Panel has generic labels
    • Cover with White on Black P-Touch labels
  • Eurorack power connector - can use either 2x5 or 2x8 IDC box connector
    • Series resistors/protection diodes on +12/-12V connections

Daughtercard Prototyping Area

  • +5V connections are directly connected to +5V pins on IDC connector if 16 pin IDC connector is used
  • If a 10 pin IDC connector is used the +5V connections are no connected to the Eurorack power
  • This is used with an Arduino Nano or Arduino Pro Mini, RAW power can be fed from the +12V and the +5V gets connected to the Arduino module

Optional 5V regulator on card

  • Can also put a regulator on the card
  • RA1 is R1 on daughtercard
  • R1/D1 are on the card

Jacks/Headers/Pots

Controls Card - Jacks/Headers/Pots

  • 0-6 Jacks
  • 0-6 Pots
  • Headers to connect to Prototyping card

J1-J6 Jacks

ER-PROTO-02 JACKS.PNG

  • Jacks have resistors on Tip/Ring-Switch
    • Typically Tip = 0 Ohm jumper, Ring/Switch = Do Not Populate (DNP on schematic)
  • Tip resistors: R7, R9, R11, R13, R15, R17
  • Ring/Switch resistors: R8, R10, R12, R14, R16, R18

J7 Header

ER-PROTO-02 jacks J7.PNG

  • 2x8 female header

J8 Header

ER-PROTO-02 pots J8.PNG

  • 2x10 female headers

Pots

ER-PROTO-02 POTS.PNG

  • Pots have optional pull-up/pulldown jumper positions
    • Install jumpers if pots are used as controls voltages
    • Do not install jumpers if pots are used as volume control voltages

Prototyping Daughtercard

  • Controls card connections are typically male headers
