M5Stack COM.GSM Module SIM800C Bulid-in 2G Communication Module ESP32 Stackable Module with SMA Antenna Description

Description: COM.X GSM is a stackable 2G communication module, with the SIM800C communication module built-in. The working frequency of COM.X GSM is GSM/GPRS 850/900/1800/1900MHz,and it can transmit SMS and data information with low power consumption. The module has a DC power input and can provide 5V-12V power supply through an external power supply. In order to facilitate the user to configure the pins, the DIP switch is used to set the pins. This module is especially suitable for remote meter reading, smart wearables, smart parking, municipal management and other IoT industries with ultra-low power consumption and small size as the core requirements. Features: - Stackable design - Support SMS text and data transmission - Independent external power supply - AT command control - SIM card type: MicroSIM - Status signal: two LED indicators (power/network status) - Power supply voltage: 3.4-4.4V - Typical power consumption in sleep mode: 0.88mA - External antenna: SMA antenna 2.5dBi - Serial communication: UART 115200bps - Operating temperature range: -40ÂC to 85ÂC - Frequency band: * Quad-band 850/900/1800/1900MHz * GPRS multi-slot class 12/10 * GPRS mobile station class B - data transmissionï¼ * GPRS class 12: Maximum 85.6 kbps (uplink/downlink rate) * Support PBCCH (Packet Broadcast Control Channel) * Coding scheme: CS 1, 2, 3, 4 * Integrated TCP/IP TCP/IPãUDPãHTTPãFTP protocol * Support USSD (Unstructured Supplementary Services Data) Package Included: - 1x COM.X GSM module - 1x SMA antenna Applications: - Remote meter reading system - Automatic Web Spider SMS-notifier - Wireless communication Specification: Resources Parameter Frequency band GSM/GPRS 850/900/1800/1900MHz Network protocol TCP/IP/UDP/FTP/HTTP etc. Communication UART 115200bps Antenna Gain 2.5dB 1880-1900MHZ/2320-2370MHZ 2575-2635MHZ Net Weight 40g Module Size 54*54*13.2mm Package Size 60*57*17mm Noteï¼ 1. COM GSM RXD/TXD can be connected to M5Stack's UART (TX(0/13/17)RX(5/15/16)) by setting the DIP switch. Since these GPIO in M5Stack Fire 16/17 are connected to PSRAM by default, conflicts may occur when using GSM. It is recommended to use any set of UART pins in the remaining two groups. 2. The DIP switch on the right is invalid for the GSM module, no need to set.
