SIM800L GPRS GSM Module PCB Antenna SIM Board Quad band | SIM800L GPRS Module gsm Card Micro Sim Card Quad-Band TTL Serial Port with Antenna for Arduino MCU

• 【SIM800L】 Chip: SIM800L; Voltage: 3.7-4.2V
• 【COMPATABLITY】 China Mobile, China Unicom and global quad-band network
• 【Design compact】 TTL serial port for serial port, you can link directly to the microcontroller. No need MAX232
• 【High performance】 TTL serial port for serial port, you can link directly to the microcontroller. I do not need MAX232. Power module automatically boot, homing network.Onboard signal lights all the way. It flashes slowly when there is a signal, it flashes quickly when there is no signal
• 【Important!!】 The module can be a bit power hungry, especially during mobile network activity If your power source can't keep up, the module will shut down / reset in the middle of the action. Powering from your computer's USB port might not be sufficient for all operations! You might have luck placing a capacitor (1000uF and more) parallel to the voltage supply, but an external power supply (USB charger, wall wart, lab power supply) might be a better choice.

Description SIM800L GPRS GSM Module PCB Antenna SIM Board Quad band for MCU Arduino DESCRIPTION: Chip: SIM800L Voltage: 3.7-4.2V Support networks: China Mobile, China Unicom and global quad-band network Module size: 2.5cmx2.3cm TTL serial port for serial port, you can link directly to the microcontroller. No need MAX232 Power module automatically boot, homing network Onboard signal lights all the way . It flashes slowly when there is a signal, it flashes quickly when there is no signal Suitable for xDrip Parakeet project Caution! : This module itself uses input voltage of 3.7V – 4.2V. Therefore, if you directly connect the Vcc pin to Arduino 5V pin, it might damage the module as well.
