Dorsal DR28 Two row header adapter. Included in Dolphin kits

One Dorsal DR28 will be included in all Dolphin experimenters kits.  

The Dorsal DR28 adapter will allow testing of modules on the Flipper Zero with the Dolphin Experimenters Board that have up to 2x8 headers such as the CC1101 wireless RF transceiver, ESP01 Serial Wi-Fi transceiver, and nearly any module with this type of header with up to 16 pins.  It will plug into the breadboard section of the Dolphin board.  The reason the top header is offset to the right is so that the supplied jumper wires that come with the Dolphin kit can be used.  The two, 2-pin headers on the bottom are only for physical support and are optional to install, I recommend not installing them as the DR28 is very secure with just having the 16 pins plugged in. 

The connections are symmetrical meaning that pin 1 of J1 goes to the upper left pin of J3 and pin 1 of J2 goes to the lower left pin of J3.  

The DR28 can be plugged in to the far right, left or middle of the Dolphin breadboard area and can even have some pins hanging out and use two of these boards sort of back-to-back with the female headers away from each other, see photos of this under the Dolphin kit where you can see two of the five I2C devices plugged into a DR28 and are hanging off the side of the Dolphin board.
