Features

The SIM800H is a quad-band GSM/GPRS module with compact size (24x24x3mm) and low power consumption. Key features:
- Quad-band GSM/GPRS: Supports 850/900/1800/1900MHz.
- Data Transfer: GPRS Class 12 (max 85.6kbps download, 42.8kbps upload).
- Voice & SMS: Supports calls, DTMF, and SMS (text/PDU mode).
- Low Power: Sleep mode (1mA), ideal for battery-powered devices.
- Interfaces: UART, GPIO, ADC, PWM, I2C, SPI.
- Embedded Protocols: TCP/IP, HTTP, FTP, MQTT.
- GNSS (Optional): Supports GPS/GLONASS for location tracking.
- Operating Range: -40°C to +85°C (industrial-grade).
- Audio: Built-in microphone amplifier and speaker driver.
Suitable for IoT, M2M, and remote monitoring applications.

Pinout

The SIM800H is a compact GSM/GPRS module with 40 pins (20 pins on each side). Key functions include:
- Power Supply (VCC, GND): 3.4V–4.4V input.
- Serial Communication (TXD, RXD): UART for AT commands.
- SIM Interface (SIM_DATA, SIM_CLK, SIM_RST, SIM_VDD): Supports 1.8V/3V SIM cards.
- Audio (MIC+, MIC-, SPK+, SPK-): For voice calls.
- Network Status (NETLIGHT): Indicates network activity.
- Reset (RST): Hardware reset pin.
- GPIOs: Configurable for various functions.
It supports GSM/GPRS, voice calls, SMS, and TCP/IP. The pinout is similar to the SIM800L but with additional features.
