For a longer time I own the NanoPi Duo2 from FriendlyARM including the IoT-Box Carrier Board. The specs of the NanoPi Duo2 and IoT-Box are as follows:
NanoPi Duo2:
- CPU: Allwinner H3, Quad-core Cortex-A7 Up to 1.2GHz
- DDR3 RAM: 512M
- Connectivity: 10/100M Ethernet
- WiFi: 802.11b/g/n
- Bluetooth: Bluetooth V4.0 of 1, 2 and 3 Mbps.
- Camera: OV5640
- ...
IoT-Box Carrier Board:
- Onboard quad-band GSM/GPRS module
- 2 x USB Host
- Serial port and Ethernet port
- Audio input and output
- MicroUSB power input and a power switch
- IPX to SMA WiFi converter
A lot of features are not accessable from the board itself like the ethernet port. One of the reason I also bought the IoT-Box. Another nice feature of the IoT-Box is the GSM/GPRS module (SIM800C), which will be the main focus of this article.
