3 Hardware Setup

The NanoPi Duo2 can be mounted on the NanoPi Duo2 IoT-Box carrier board. You can refer to the following setup to assemble them:
NanoPi Duo2 IoT-Box_NanoPi_Duo2

You can connect your NanoPi Duo2 IoT-Box board to a network and external modules such as USB devices
NanoPi Duo2 IoT-Box

When you use the onboard quad-band GSM/GPRS module you should use an appropriate antenna and this antenna's band is different from an WiFi antenna's band. You can refer to the following setup:
