Description

Product Introduction:
This module is designed with a 5V/3.3V microcontroller logic conversion circuit because the GSM/GPRS core is 2.8V, which is different from the logic level of a regular microcontroller of 3.3V or 5V. Many other development boards have not designed this part of the conversion circuit, and prolonged use can cause damage to the microcontroller or GSM module
Product Highlights:
5V: Power supply pin, can only input DC5V, used to supply power to the board
V-TTL: Connected to the 5V/3.3V core voltage of the target control board microcontroller (distinguished by the number of V cores of its own microcontroller), this pin is used to convert the TXD and RXD of the GSM module board into corresponding TTL logic
GND: power ground wire
TXD: Module serial port sending pin, JTL level (cannot be directly connected to RS232 level)
RXD: Module serial port receiving pin, TTL level (cannot be directly connected to RS232 level)
DTR: Data Terminal Preparation
SPKP: Core audio output pin
SPKN: Core audio output pin
MICN: Core audio input pin
MICP: Core audio input pin
RI: Kernel ringing prompt pin
VRTC: RTC external battery pin
GND: power ground wire
PWR: Pulling down this pin can enable the module to be turned on or off
GND: power ground wire
VBAT: Potassium battery input pin, 3.3V-4.4V
Package Type:
All goods will pack into cartons and wrapped full of waterproof tape before shipment.

We can accept customized package to meet different requirements:
1.Every item will separately pack into plastic bag,component,module can be packed in anti static bag.
2.Some fragile products such as the display screen can be packed in bubble bag.
3.Some large machines can be packed in wooden cases.
4.We can label JH code or client's code on package so that customers can check easily after receive goods.
