For each pad shown in the picture above, cut a length of 30 gauge wire wrap wire long enough to reach from the pad on the PCB to the indicated pad on the Teensy (note: be careful to connect to the correct pad on the Teensy as some of the pads, such as those for pins 21, 22 and 23 are labelled at an angle on the Teensy.)

Next, strip just enough insulation from the end of each wire to make a good connection to the appropriate pads. Since you've already applied 60/40 solder to these pads, you should be able to hold the tin-plated wire to the pad and touch it with the soldering iron to reflow the solder to make a good connection. Then, bend the wire, as needed to route it to the connecting pad on the Teensy. I recommend that you also first pre-apply 60/40 solder to the needed pads on the Teensy so that you make the connection on the Teensy side by holding the wire to the pad while you reapply heat with the soldering iron.

Repeat the above steps for all of the needed connections. I recommend first making all the connections from the 14 Pin PIN and then make the connections from the 28 pin PIC and, finally, from resistor R7, as listed below:

  • Connect D8 on the PCB to pin D8 on the Teensy
  • Connect D7 on the PCB to pin D7 on the Teensy
  • Connect D6 on the PCB to pin D6 on the Teensy
  • Connect D11 on the PCB to pin D11 on the Teensy
  • Connect D12 on the PCB to pin D12 on the Teensy
  • Connect D16 on the PCB to pin D16 on the Teensy
  • Connect D17 on the PCB to pin D17 on the Teensy
  • Connect D14 on the PCB to pin D14 on the Teensy
  • Connect D13 on the PCB to pin D13 on the Teensy
  • Connect D5 on the PCB to pin D5 on the Teensy
  • Connect Gnd on the PCB to the Gnd pin closest to the USB connector on the Teensy
  • Connect USB+ on the PCB to the D+ pad on the Teensy
  • Connect USB- on the PCB to the D- pad on the Teensy
  • Connect D21 on the PCB to pin D21 on the Teensy
  • Connect D20 on the PCB to pin D20 on the Teensy
  • Connect D22 on the PCB to pin D22 on the Teensy
  • Connect the pad on the left side of R7 to the VUSB pad on the Teensy

When completed, your PCB connections should look like this:
