## Description
**NB-IoT Plus** is a wireless communication module, integrated with the NB-IoT **M5311-GB** module from China Mobile. It supports multiple frequency bands such as B1 / B3 / B5 / B8 / B20 / B28. It's very tiny form factor gives more convenience for applications with flexible dimension requirement. It comes with a built-in copper helical antenna, and also an I-PEX connector, reserved for adding an external antenna to obtain better signal strength.Package with LCC allows quick production through standard SMT, which provides a more reliable connection method and performance in extreme environments.The power requirement of this M5311-GB module is as low as 2.1V,it supports and can fully utilize the power of AA battery, to provide an extremely low-power-consumption solution for field deployed terminal devices.M5311 provides abundant external interfaces and protocol stacks, and also support for peripheral sensors, etc.Based on M5311-GB, we have offered extra hardware resources to the NB-IoT Module, WUP and STA LEDs, 3 alternative UARTs, a power button, and support for two alternative antennae.

**Please notice:** There are 2 types of **M5Camera**
- Model A & Model B
- They have different circuits, can be identified by backside sticker
- Model A is halt production. The new coming **M5Camera** is just Model B
- In Model A circult design MPU6050 and camera sensor have I2C conflict, which means you can't use both at the same time.
- Model B have better performance on image quality and processing speed.
