Once you have your PCB, the next step is to place the "pogo pins".
What are these pogo pins anyway?
Pogo pins are basically spring-loaded metal sticks. They are used to test specific pins on each board.
The pogo pins in this guide are about 0.5" long and have a spear point. They also fit snugly into 'standard' 0.035" (0.9mm) drill holes so they are easy to insert and stand up straight. We carry these pogo pins in the Adafruit shop! They're called "P75-LM" type, you can also pick them up on ebay. If you're buidling something that will be used for a long time it's probably a good idea to use socket holders.

The pogo pins may be skewed all over the place at this point. That's ok, we're going to fix it!
- Attach standoffs to the board.
- The screws go underneath the board and attach to the standoffs on top.
Repeat this process for all pogo pins
For comfort, you may want to switch the position of your PCB to a stand.
Install LED, making sure it's oriented correctly (longer leg is the anode).
Clip off any excess from the LED with snips.
Solder piezo buzzer into place.
These little buzzers are great for adding an auditory element to any test procedure.
- Break up your headers into (1x) 6 pin, (1x) 10 pin, and (2x) 8 pin headers.
- Place accordingly on Metro.
- Now place the PCB on top of the headers, pushing down the PCB into place in needed.
- Now solder the header pins to the PCB.
Give it some rubber booties!
These little adhesive rubber feet will prevent your tester from slip-sliding all over the place while you're trying to use it.
