HOW TO – Make a pogo pin testing jig

HOW TO – Make a pogo pin testing jig. For more complicated projects, you may need to have a longer testing procedure in which case we can make multi-step testers that also keep the PCB held down with little ears! The plastic pieces hold down the PCB against the pogo bed.

This tester, when used with a little batch script, performs the following test:

  • Reprograms the board’s fuses and flash with a bootloader (via the ISP port). For this part we’re using the Arduino as an ISP programmer (there’s a sketch that does this)
  • The computer then bootloads (via USB) a pin-by-pin testing program
  • Once the board indicates the test completed, the computer erases the testing program

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. Nice take on a bed-of-nails test fixture. Any plans for a flying probe (woodpecker) tester?

  2. “They also fit snugly into ‘standard’ 0.35″ (0.9mm) drill holes so they are easy to insert and stand up straight. ”

    Should read 0.035″, missing zero.
