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.
