Highlights

Onboard OLED Display

The integrated OLED display can be used to show some information such as systemstatus and

parameters, making it convenient for users to directly use the entiredevelopment board for their own

product design.

UsB Type C

The power supply, firmware download, and debugging interfaces adopt a moreuniversal USB Type C

interface, making development work more convenient.

Plastic Shell

We also made a plastic shell as an optional accessory. Which provide basicprotection for the

development board.

WiFi LoRa 32 (V3) supports the following development methods:

WiFi LoRa 32 is compatible with the following open-source projects:

ESP32 Paxcounter

Disaster Radio

Meshtastic

Tiny GS
