The Unwelded SIM800C GSM GPRS Module Development Board is a versatile communication solution for STM32 and C51 microcontroller projects. Offering compatibility with both 5V and 3.3V TTL levels, it facilitates seamless integration. The IPEX interface ensures antenna connectivity, and it features Bluetooth functionality for additional wireless capabilities. The SIM800C GSM GPRS module, supports reliable mobile communication, making it an ideal choice for applications requiring GSM connectivity, such as remote monitoring and IoT projects. The board's flexibility and unwelded design cater to customization based on specific project requirements.

Pin Description:
  • 5V: power supply pin, the only input DC5V, used to power the board. V_TTL: access control board microcontroller core target voltage of 5V / 3.3V (according to its own microcontroller is much to distinguish kernel v), this pin is used to convert the GSM module board TXD and RXD for the corresponding TTL logic.
  • GND: power supply ground
  • TXD: send pin serial port module, TTL level (not directly connected to RS232 level)
  • RDX: receive pin serial port module, TTL level (not directly connected to RS232 level)
  • DTR: Data Terminal Ready
  • SPKP: Core Audio output pin
  • SPKN: Core Audio output pin
  • MICN: Core Audio input
  • MICP: Core Audio input
  • RI: Ring core pin tips
  • VRTC: RTC pin external battery
  • GND: power supply ground
  • PWR: This pin can turn down or turn off the module
  • GND: power supply ground
  • VBAT: lithium battery input pin, 3.3v-4.4v

Features:

  1. Supports both 5V and 3.3V TTL levels for flexible integration.
  2. Facilitates antenna connectivity for reliable GSM/GPRS communication.

1 x Unwelded SIM800C GSM GPRS Module 5V/3.3V TTL Development Board IPEX with Bluetooth for STM32 C51

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
