Little name badge sized PCB to make LEDs go blinky, using an ATTINY13A and a CR2032 battery.
My first proper microcontroller and PCB design, made for a convention that I ended up not attending. Hopefully it can be of use to others out there.
You can get this badge made and assembled by PCBWay here!
I use a 6 pin, 1,27mm pitch pogo pin adapter like this for programming. You could also solder wires to the pads, or use something else with the same pitch. Any ISP programmer, such as USBASP or Arduino as ISP should work.
