Bpod/OpenEphys Sync Board

The Open Ephys sync board allows behavior and events logged by Bpod to be sent to an Open Ephys electrophysiology system.

Note: Bpod state machine 0.7+ does not require the sync board.

It's very simple to build. Here's how.

  1. Order all parts in the Bill of Materials
    • These parts can be purchased from commercial suppliers except for the printed circuit board.
    • We have previously used SeeedStudio's FusionPCB service as follows:
      • QTY: 10
      • PCB Layer: 2
      • PCB Thickness: 1.6mm
      • PCB Dimension: 5cm max X 5cm max
      • PCB Color: green
      • Surface Finish: HASL
    • This should work out to ~$2.39 per board for an order of 10 boards (Jan 2014). Select "Next".
    • Select C:\Bpod\CAD\PCB\OpenEphysSync\OpenEphysSync_r1_Gerber.zip and finish the order.
  2. Gather tools. You'll need:
    • A clean soldering iron and sponge
    • Solder
  3. Follow the assembly instructions.

Assembly instructions

Solder the three components into the board as shown below.

The HDMI connector pins are surface mount, and will require special soldering techniques.
