## Description

An all-in-one development board combining an ATmega32U4 microcontroller with an A9G GPRS/GSM/GPS module. Capable of making voice calls, sending SMS text messages, and providing GPS positioning — all controllable via AT commands over serial. The board includes analogue, I2C, and digital expansion interfaces for connecting additional sensors and modules. The A9G module supports quad-band GSM (850/900/1800/1900 MHz) for worldwide 2G network compatibility, GPRS Class 10 data, and GPS positioning with less than 2.5m horizontal accuracy. A 3.5mm headphone jack is included for voice audio. Key Features ATmega32U4 + A9G – Arduino-compatible MCU with integrated GSM/GPRS/GPS Voice, SMS, and Data – Make calls, send texts, and transfer data over GPRS GPS Positioning – Less than 2.5m horizontal accuracy Quad-Band GSM – 850/900/1800/1900 MHz for global 2G coverage 3.5mm Audio Jack – For voice calls with headset Low Standby Current – ~3mA or less in standby AT Command Control – Standard GSM 07.07/07.05 and Ai-Thinker extended commands Specifications MCU – ATmega32U4 Cellular Module – A9G Working Voltage – 3.3–5V GSM Bands – Quad-band 850/900/1800/1900 MHz GPRS Class – Class 10 (85.6 kbps down, 42.8 kbps up) GPS Accuracy – <2.5m horizontal Baud Rate – 115200 bps Standby Current – 1.2–1.3mA (DRX dependent) A9G Module Size – 19.2 × 18.8 × 3mm Operating Temperature – -30°C to +80°C Protocol Stack – PPP/TCP/UDP/HTTP/FTP/SMTP/MUX Speech Coding – HR, FR, EFR, AMR Certifications – RoHS, FCC, CE, CTA Expansion Interfaces 1× Analogue input 1× I2C interface 2× Digital interfaces Ideal For GPS tracker projects Remote monitoring and telemetry over 2G IoT devices requiring cellular connectivity SMS-based alert and notification systems Package Contents 1× 32u4 with A9G GPRS/GSM/GPS Board Note: Ensure your SIM card is not PIN-locked before inserting. This board is supplied without an insulated housing — take ESD precautions, especially in humid conditions. Resources User Manual and Wiki (Elecrow)
