[EOL] GSM Module SIM800L with MIC & Headphone Jack

PRODUCT DETAILSDescription SIM800L is a cellular phone module, integrated SIM800L, a GSM/GPRS module, only compatible with 2G network. if you want to integrate a cellular module into your design with voice, text and SMS, this hand-solderable module is pretty nice!This product is EOL now.Product Features 3.5 mm phone audio jack MIC (MIC is disable by default. To enable it, you will need to weld a 0 ohm resistor at MIC-EN ) Supply voltage: 3.8V - 4.2V Recommended supply voltage: 4V Power consumption: sleep mode < 2.0mA idle mode < 7.0mA 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 Spring Antenna on board Status signaling: LED Working temperature range: -40 do + 85 ° C M5Stack Fire has occupied GPIO16 / 17 to connect with the PSRAM by default, it's conflict with TXD / RXD (GPIO16, GPIO17) of SIM800L module. Therefore, when using the SIM800L module with the M5Stack Fire, you might have to cut the TXD and RXD from SIM800L module and wire fly to another set of UART pin Include 1x M5Stack SIM800L Module Applications Nitrogen dioxide alarm Automatic Web Spider SMS-notifier Remote meter reading system Specification Resources Parameter Net weight 17g Gross weight 27g Product Size 54.2*54.2*12.8mm Package Size 60*57*17mm LEARN AND DOCUMENTSDOCUMENTS
