SODAQ ONE BLE shield

Overview:

The SODAQ ONE BLE 4.2 shield is an inexpensive yet simple way to add Bluetooth Low Energy (BLE 4.2) to your SODAQ ONE within seconds. It maintains the ultra compact form factor of the SODAQ ONE that you love, and by "piggy-backing" it onto the SODAQ ONE there is even enough space left to fit a 240mAh rechargeable battery (sold separately) as shown in the pictures.
