This is an ingenious little tool that will come in especially handy if you make your own PCBs and want to keep them small and slim. Ever made a tiny PCB only to have the programming header pins sticking out way above the rest of the board? This USB to UART programmer with pogo pins will do away with all of that while also letting you program your boards in the blink of an eye. You could of course put some other type of programming header on your board, but this way is easier, and much faster if you have 20 or 200 boards to program.
The creator of this little adapter is called Phoenic CNC, and they also make the OLEDiUNO range of products. They are little cubes with OLED screens on the front. The cubes are made from layers of PCBs with each OLEDiUNO containing a different type of sensor. You can get GPS, Tachometer, Spectrum Analyser, Gear indicator for cars/motorcycles and so on.
You can see the pogo pin adapter being used to program some OLEDiUNO boards in the video below. It’s a really handy tool to have especially if you hate using header pins for programming your boards.
