Cat1 Global 4G LTE communication expansion board WT271 base on Fibocom LE271 module Compatible with ESP32-S3 / ESP32-P4 / ESP32-S31

WT271 4G expansion board WT271 4G expansion board is a Cat.1 communication expansion board based on the LE271 cellular communication module. The board integrates a Nano-SIM card socket, an IPEX-1 antenna connector, a multifunction USB 2.0 interface, a dedicated USB-C power input, and an AT UART debug interface. It is primarily designed to add cellular network connectivity to compatible development boards. Product Features: 1. LE271 cellular communication module: An onboard LE271 module communicates with an external host through USB or UART. 2. Nano-SIM interface: Onboard self-ejecting Nano-SIM card socket. 3. External antenna connector: An IPEX-1 coaxial connector is provided for a cellular antenna. 4. Dual USB-C interfaces: J6 accepts the 5 V system power input; J5 connects to a compatible development board and provides both 5 V power and USB 2.0 data connectivity. 5. UART debug interface: The 7-pin interface supports sending AT commands through a ZXACC_ESPDB debugger. 6. Compact PCB: The board measures approximately 38 mm x 38 mm.
