GSM/GPRS/GPS Shield (B)

GSM/GPRS/GPS Shield (B) is an Arduino shield based on the Quad-band GSM/GPRS/GPS module SIM808.b Arduino connectivity, compatible with UNO, Leonardo, NUCLEO, XNUCLEO. Onboard USB TO UART converter CP2102 for UART debugging. 5 x LEDs for indicating the module working status. Onboard voltage level converter, supports both 3.3V and 5V systems. SIM card slot for 1.8V/3V SIM card. Baudrate auto detection (1200bps ~115200bps). Bluetooth 3.0， supports data transferring through Bluetooth. RTC with power supply interface. Firmware upgradable via USB. Control via AT commands (3GPP TS 27.007,27.005, and SIMCOM enhanced AT Commands). Supports SIM application toolkit: GSM 11.14 Release 99. Operating voltage: 6 ~ 12V. Operation temperature: -40 °C ~ +85 °C. Storage temperature: -45 °C ~ +90 °C.
