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.

Description
Connect your Raspberry Pi to GSM/GPRS cell phone network with this shield. This Raspberry Pi GSM/GPRS shield lets you connect to the internet in the areas where is devoid of Wi-Fi or Ethernet. Quectel M66 module is the heart of this Raspberry Pi add-on. M66 is a quad-band GSM/GRPS module based on the latest 2G chipset which has the optimal performance in SMS & Data transmission and audio service even in harsh environment. You can plug a headset and make a call to someone easily.

Both UART and USB communication with the M66 GSM module is available. The shield can be used easily via easy-to-use AT commands.

The compact form factor, low power consumption and extended temperature make M66 one of the best choices for M2M applications such as wearable devices, automotive, industrial PDA, personal tracking, wireless POS, smart metering, telematics, and more.

Features
Fully compatible with Raspberry Pi models that have the 40-pin GPIO header (3, 2, B+, A+, Zero)
High Data Speed: GPRS Multi-slot class 12, 85.6kbps downlink and 85.6kbps uplink data rates
Quad-band: 850/900/1800/1900MHz
Built-in PCB antenna, also there is an external antenna port available
Supported Protocols: TCP/ UDP/ PPP/ FTP/ HTTP/ SMTP/ CMUX/ SSL
Quectel’s QuecLocator Feature, lets you get the location without GPS/GNSS
Extremely low standby power consumption by M66, 1.3mA at DRX=5
Efficient and low quiescent current regulator circuit can hold up to 3.6A
Bluetooth Function, V3.0 specification, SPP and OPP profiles available.
Micro SIM Card socket can easily reachable on the downside of the shield.
Can be used standalone with PC/Laptop over micro USB, without stacking with Raspberry Pi thanks to FTDI chip on the shield.
