Introduction:

UART Interface: The module supports 3 UART interfaces. Two are 4-wire
UARTs, and the last one is 2-wire UART, which is only for
debugging.
USB Interface: The USB interface supports USB 2.0 high speed standard.
USIM Interface: The USIM interface provides the interface for a USIM card.
External Power
Supply:
DC 3.8 V is recommended.
Audio Interface: The module supports one PCM interface. This function is
under development.
RF Pad: RF antenna interface.
Tunable ANT
CTRL:
Since LTE bands cover wide frequency, tunable ANT CTRL
helps customer for tunable antenna design. This function is
under development.
ADC: Reserved for intelligent module in future.
SPI Interface: Reserved for intelligent module in future.
SDIO Interface: Reserved for intelligent module in future.
HSIC Interface: Reserved for intelligent module in future.
I2C Interface: Reserved for intelligent module in future.

Advantage
ME909s-821 supports 150Mbps downlink data rate, including enhanced features like FOTA, USSD and Huawei enhanced AT commands.

ME909s-821 supports China region LTE Bands including both FDD-LTE & TDD-LTE, and has two different form factor: LGA and Mini PCIe form factor.

With Huawei pin-to-pin form factor, it is easy to migrate from MU609, MU709 or ME909u family to ME909s-821.
