LTE M8321 Module Wireless Communication Module GSM GPRS 4G M2M Industrial M5Stack® for Arduino - products that work with official Arduino boards

Description: This is a wireless communication module, integrated an NB-IOT M8321 module that released by China Mo bile, provided TD-LTE/FDD-LTE/WCDMA/TD- SCDMA/GSM/GPRS/EDGE Frequency Band and LCC+LGA package type. It has integrated plentiful Internet protocols, field standard interface, and functions, supported WindowsXP,Windows7,Windows8,Windows10,Linux and Android USB driver. In the LTE-4G module scheme, we added more hardware resources, 1 reserved speaker solder panel, 3 LEDs, exported USB interface, double antennea allowed. M8321 is 4V power input, so in the hardware of LTE-4G module, we added a Bidirectional Voltage-Level Translator (TXS0104E) to switch the power supply to 4V. In telecommunication, Long-Term Evo lution (LTE) is a standard for wireless broadband communication for mo bile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements.
