Nano IO shield for XBEE and NRF24L01 Socket

Nano ch340 is a small control board based on Arduino, very popular for everyone. But sometimes it is troublesome to connect a bunch of sensor modules and external power. So we particularly design this Nano IO shield.
This simple NANO IO shield extends all the digital and analog pins of Nano ch340 out into 3PIN (GND, 5V, signal), easy to hook it up to make experiments.
It also has some common communication pins like serial and I2C communication. On the shield comes with a Bluetooth Bee wireless header, a NRF24L01 wireless module header, and a black DC jack that can supply external power DC 7-12V to Nano ch340.
