Product Description


The SIM900A is a GSM / GPRS Dual-Band known for its small size and low power consumption. It is able to communicate with the controller through AT commands (GSM 07.07, 7.05 and SIMCOM controls most used). Given the small size, they are not present on the module status LEDs and buttons so standard tasks as start, stop and reset must necessarily be carried by software. Also, thanks to its characteristics already mentioned, is used to develop devices very compact as locators, GSM telephone combiners, telecontroller, remote alarms, etc.
