h-nanoGSM - nano GSM shield :: FEATURES AT A GLANCE:

Quad band GSM/GPRS module (Quectel M66F) with true worldwide coverage: 850MHz, 900MHz, 1800MHz and 1900MHz.
Bluetooth 3.0 interface with SPP and HFP profile support.
Very compact and light weight: compact as 1.25"x1.16"(31.75x29.46mm) and with weight around 8g, probably the best on his class. Not only a GSM break board, but an GSM shield in nano format having big soldering pads, for convenient integration and handling.
Embedded USB adapter with SERIAL to USB bridge adapter - with micro-USB type A socket (you can connect the h-nanoGSM shield, via USB or SERIAL TTL with your Raspberry PI or you can use it as wireless USB modem with your Windows or Linux PC) (unique feature).
Digital interface (SERIAL and CONTROL interfaces): 2.8-5V auto-level (UART TX+RX / POWER ON-OFF / RI / STS / RTS ); you can directly connect (without the need for any level adapter board) the h-nanoGSM shield with any 3/5V Arduino shield or any version of RASPBERRY PI, BEAGLEBONE, BANANA PI or any other 2.8V up to 5V compatible microcontroller. The digital (and powering) interface it is available in standard 0.1"(2.54mm) pin header and it is pin 2 pin compatible with our dual SIM GSM micro shield c-uGSM shield and with our 3G micro shield d-u3G shield.
Embedded LiPol battery charger - the h-nanoGSM shield can run in configurations with or without Lithium Polymer battery, depending on chosen powering schema.
Analog audio interface (output- 32ohm speaker, in- capacitor MIC) - via standard 0.1"(2.54mm) pin header and via BLUETOOTH audio interfacing
Embedded switch: control for modem ON/OFF
Multiple powering schemas: - via USB, via POWERING, SERIAL and CONTROL interface (digital inteface) or via optional external(20.3x34.29mm) pin to pin plugable 5-25V switching power supply
Extended Arduino and RaspberryPI code examples support files: - GSM, SMS, DTMF, TCP/UDP, HTTPS and HTTP over GPRS**, smart features like RAM DISK SYSTEM + FLASH FILE SYSTEM for FILE STORAGE and other. RaspberryPI PPP and TCPIP routing support (RaspbianOS) trough easy installation and usage scripts. And, last but not least, h-nanoGSM is supported by our "mobile IoT 2 CLOUD" for Arduino prototype - quite tiny IoT implementation (~16Kb free on ATMEGA328), with mobile data transfer optimization** and based on our original "IoT2CLOUD ABSTRACTIZATION LAYER"© concept.
* High Speed GPRS Multi-slot class 12 (configurable 1~12) Downlink and uplink speed - 85.6 kbps max.
** Extra license charges may apply and special EULA must be accepted.
