ESP-32 TTGO LoRa32 V2.1_1.6 Version 433/868/915Mhz ESP32 LoRa OLED 0.96 Inch SD Card Bluetooth WIFI Wireless Module

Paramenters:

At the TTGO LoRa V2.1 ,we add the S-M-A and IP5306 to the board,which make it can do more things.
In terms of the power switch, we have changed the switching interaction mode.
The added S-M-A antenna can enhance signal transmission.Product Description
