USB Type C

The power supply, firmware download, and debugging interfaces adopt a more universal USB Type C interface, making development work more convenient.

Plastic Shell

We also made a plastic shell as an optional accessory. Which provide basic protection for the development board.

Onboard OLED Display

The integrated OLED display can be used to show some information such as system status and parameters, making it convenient for users to directly use the entire development board for their own product design.

FAQ

Can the onboard 2.4GHz antenna be replaced?

The 2.4GHz antenna is a spring antenna, and there is no additional interface on the board for 2.4GHz wireless signals.

Can ESP32’s WiFi and Bluetooth be used at the same time?

No, the WiFi LoRa 32 don’t have an external PSRAM, if your application need use Bluetooth and Wi-Fi at the same time, you can look into this product: Heltec Wireless Bridge.
