The key to successful AVR programming :->
The previous version of this adapter had a major disadvantage – assembly was a mess. You needed a jig, sticky tape… not good.
This one is much better in that respect.
Pogo-pin alignment is facilitated by split extra-long pads on the circuit board. It still requires dexterity and patience, but there is no more guesswork involved. If the pins are pushed into the gap of the split pins, they will be straight.
Another advantage is better mechanical support for the pins. Less chance of accidentally snapping them off.
