SIM800L GSM/GPRS module with 3.5 mm audio jack and microphone, designed for M5Stack projects. 2G quad band network compatible.
The M5Stack GSM Module SIM800L adds cellular communication capabilities (voice, SMS, GPRS data) to your M5Stack projects. It features a 3.5 mm audio jack and microphone for telephony, with an integrated spiral antenna and an IPX connector for external antennas.
M5Stack Fire Compatibility: Since GPIO16/17 are used by default for the Fire's PSRAM, UART communication with the SIM800L may conflict. You may need to cut the TXD/RXD traces and connect the module to alternative UART pins.
