Technical Data:
TXD: serial transmit, 3.3V TTL level.
RXD: serial receiver, 3.3V TTL level.
CTS: serial flow control, is not supported.
RTS: serial flow control, is not supported.
DC: simulation, burning clock pin.
DD: simulation, data burning feet.
RST: reset pin module requires low level of not less than 5ms reset.
VCC: module power foot, requiring DC 3.3V power supply current is not less than 100mA.
GND: module common ground.
LED: LEDs module output pin, high output, series resistor connected LED.
Slave bright one second every two seconds. Once connected, LED lit.
KEY:. Input pin, internal pulldown This foot high, clear the record for the host address from the machine.
PIO: extended functionality for setting the module master-slave mode, the default internal pull-up resistor from the machine; external 1K pull-down resistor connected to ground, as the host. Currently only supports 9600bps communication, does not support the AT commands. Host, when pass-through traffic from the machine, there must be a certain time interval between packets. For example, the packet length is 500 bytes, then the transmission time interval between packets can be set to no less than 600ms. Otherwise, you may lose data.

Introduction:
N9200B is a MP3 chip that provides serial port,which perfectly integrates MP3 and WMV hard decoder chips.
It includes the N9200A and N9200B Music MP3modules,and the software supports TF driver, supports the computer to update the content of SPI-flash directly, and supports the FAT16 and FAT32 file systems.
Through a simple UART serial command or a first-line serial port instruction to play the specified music, and how to play music and other functions, without the tedious underlying operation, good sound quality, easy to use, stable and reliable is the biggest feature of this product.
In addition, the chip is also a product of deep customization, which is a low-cost solution for fixed voice playback.

This module uses the newest 2.4ghz transceiver from Nordic Semiconductor, the nrf24l01+. It integrates a complete 2.4ghz RF transceiver, RF synthesizer, and baseband logic including the Enhanced shockburst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. The ‘+’ version of the IC has improved range, sensitivity, and data rates. The command set is backward compatible with the original nrf24l01.Worldwide 2.4GHz ISM band operation 250kbps, 1Mbps and 2Mbps on air data rates Ultra low power operation Power supply : 1.9~3.6V Dimension : 12x18mm

5-18V power supply supported.- Serial USB TTL compatible for 2.85V, 3.3V and 5v signal- GSM, GPRS, GPS {text messaging, data transmission, positioning} triple function.
