4 over 2 (Emisar, Noctigon)

Lights from Hank Wang (Emisar and Noctigon brands) typically have flashing pads in two rows: 4 pins over 2 pins. These lights typically use a chip such as the attiny85 or attiny1634.

Models using this interface include pretty much every model from these brands over the last few years, such as the popular D4v2, D4Sv2, KR4, KR1, and many others.
