Fetures:

The BB-ADTR breadboard adapter makes it easy to connect any 2*4 pin device or module, such as an nRF24L01+ or ESP8266 ESP-01 module, to a standard breadboard.
The adapter has a wide enough footprint to secure the board and a connected module firmly to a breadboard, but is small enough to conserve breadboard real estate.
Made of a quality 1.6mm thick FR4 industrial-quality PCB board with the pads pre-tinned with a lead free HASL finish, we made sure this little board would be durable and easy to solder.

Please Note:
Adapter comes unassembled, soldering required.
