Based on the A9G module, it supports voice calls, SMS, GPRS data networking, and real-time location tracking — all on a single board.\n\nPacked with peripherals including a lithium battery charger, microphone and speaker interfaces, accelerometer, TF card slot, USB communication, and multiple I/O interfaces (SPI, I2C, ADC), this board is a versatile platform for IoT prototyping. It also supports a camera expansion board for 0.3MP or 2MP cameras, and can be programmed using AT commands or custom Lua scripts.\n\nKey Features\n\n\nCellular – GSM/GPRS quad-band (850/900/1800/1900 MHz)\n\nPositioning – GPS + BDS dual-mode\n\nVoice & SMS – Supports voice calls and text messages\n\nGPRS Data – Download up to 85.6 Kbps, upload up to 42.8 Kbps\n\nAT Commands – GSM 07.07/07.05 and Ai-Thinker command set\n\nSerial Ports – 3 (1 download, 1 AT command, 1 general)\n\nOn-Board Peripherals – Accelerometer, TF card slot, LEDs, user buttons, mic/speaker interfaces\n\nExpansion – Camera board support (0.3MP/2MP), SPI, I2C, ADC interfaces\n\nWorking Voltage – 3.5–4.2V (optimal at 4V)\n\nGPIO Level – 2.8V\n\nTemperature Range – −30°C to +80°C\n\nModule Size – 19.2 × 18.8 × 3mm\n\nPower – USB, lithium battery, or external supply\n\n\n\nWiring: Connect via USB-TTL with VUSB→5V, GND→GND, AT_TX→RX, AT_RX→TX. Alternatively, power via USB or lithium battery (3.3–4.2V on VBAT, press power button for 2 seconds to start). The module enters AT command mode by default.\n\n\nIdeal For\n\nIoT and remote monitoring projects\nGPS/cellular asset tracking\nVehicle anti-theft with accelerometer + GPS\nRemote camera and data logging systems\n\n\nPackage Contents\n\n1× A9G GPRS/GSM + GPS Development Board\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3565,"title":"Default Title","sku":"EC-AMC01017B","price":40.97,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
