The SIM800C GSM/GPRS Mini Development Module supports 5V adapter or 3.5-4.5V lithium battery power. It accepts 5V/3.3V TTL logic levels for MCUs and is compatible with IPEX-PCB or IPEX-SMA antennas.
The SIM800C GSM/GPRS Mini Development Module is a compact and cost-effective solution for adding cellular communication capabilities to your electronics projects. Based on the widely used SIM800C modem, it supports 2G GSM/GPRS networks (850/900/1800/1900 MHz) and enables SMS messaging and data transfer via a serial UART interface.
This miniaturized module accepts a VBAT supply between 3.5V and 4.5V (ideal for lithium-ion/polymer batteries), but can also be powered from 5V using a 1N400x rectifier diode to drop the voltage to approximately 4.2V. The UART interface is compatible with both 3.3V and 5V logic levels, making it directly compatible with most microcontrollers such as Arduino, Raspberry Pi, or ESP32 without requiring a level shifter.
