Mini gsm/gprs module: SIM 800L is a miniature cellular module which allows for gprs transmission, sending and receiving sms and making and receiving voice calls. Low cost and small footprint and quad-band frequency support make this module a perfect solution for any project that requires long-range connectivity. After connecting power module boots up, searches for cellular network and login automatically. Onboard led displays connection state (no network coverage - fast blinking, logged in - slow blinking). Notice: be prepared to handle huge power consumption with peek up to 2a. Maximum voltage on uart in this module is 2.8v. Higher voltage will kill the module. This module has antenna included made of wire (which solders directly to net pin on pcb) - very useful in narrow places. Sim800l is a quad-band gsm/gprs module, that works on frequencies gsm850mhz, egsm900mhz, dcs1800mhz and pcs1900mhz. Sim800l features gprs multi-slot class 12/ class 10 (optional) and supports the gprs coding schemes cs-1, cs-2, cs-3 and cs-4. Specification: supply voltage: 3.8v - 4.2v recommended supply voltage: 4v power consumption: sleep mode idle mode gsm transmission (avg): 350 ma gsm transmission (peek): 2000ma module size: 25 x 23 mm interface: uart (max. 2.8v) and at commands sim card socket: microsim (bottom side) supported frequencies: quad band (850 / 950 / 1800 /1900 mhz) antenna connector: ipx status signaling: led working temperature range: -40 to + 85°c
