ATmega328 Microcontroller
The onboard ATmega328 provides the main processing and control functionality. It can be programmed to read sensors, process data, control relays or other outputs, communicate with the GSM module, and display information on the LCD.
It is well suited for applications requiring a simple, reliable, and cost-effective embedded controller.
Quectel M08-R GSM/GPRS
The Quectel M08-R is an industrial-grade quad-band GSM/GPRS module supporting GSM 850, EGSM 900, DCS 1800, and PCS 1900 MHz. It supports GPRS data communication and SMS, making the board suitable for remote monitoring and control applications.
The module supports interfaces including UART, SIM, audio, RTC, and antenna connection, with GPRS data rates up to 85.6 kbps.
16×2 LCD Display
The integrated 16×2 character LCD provides a simple user interface for displaying:
- Sensor readings
- GSM/network status
- Device operating status
- Error messages
- Configuration parameters
- Counters and measurements
- System notifications
LM2596-ADJ Power Supply
The onboard LM2596-ADJ adjustable buck converter provides efficient DC-DC voltage conversion and allows the output voltage to be configured according to the requirements of the circuit.
It is useful when operating the controller from common DC power sources such as 12V or 24V supplies, subject to the board’s actual input/output specifications.
