Features USB Type-C with ESD protection, dual IP EX antennas (LoRa + 2.4GH z), 0.96 OLED display, and expanded headers. A top-tier development platform for IoT creators and Meshtastic users needing an all-in-one solution with built-in GPS, WiFi, Bluetooth, and LoRa connectivity.
^^ Note: 1. The screw securing the upper left corner of the screen is a specially customized plastic screw, distinct from the other three screws. Its purpose is to avoid interfering with the 2.4GH z radio frequency and is not defective. 2. Flash the firmware first before use, otherwise the screen will be blank. The stable version of the system does not have V4 firmware, you can use 2.7. 11 or 2.7. 12.
