2Pcs ESP32 LoRa V4 Development Board with ESP32-S3 SX1262 LoRa Module 0.96" OLED Display WiFi Bluetooth 2MB PSRAM 16MB Flash Supports GPS & Solar LoRa Antenna for AR duino Meshtastic LoRaWAN IOT

V4 Development Board: The LoRa 32 V4 is a brand-new upgrade to the classic LoRa development board. While maintaining the powerful features of its predecessor, the V4 version features comprehensive optimizations in hardware design, power management, and scalability. It is suitable for IoT applications such as smart cities, agricultural monitoring, smart homes, industrial control, security systems, and wireless meter reading, providing developers with a more efficient and flexible development experience.
^^ Powerful Connectivity: Our development board features dedicated 2.4GH z metal spring antennas for Wi-Fi and Bluetooth, and a reserved LoRa U. FL interface, ensuring stable long-range wireless communication. A new SH 1.25 -8-pin GPS interface facilitates positioning expansion. It also offers a rich set of peripheral interfaces. The development board's form factor and pinout are compatible with LoRa 32 V2 and V3 versions, and the additional external pins enhance scalability.
^^ Hardware Upgrade: Our V4 development board utilizes the ESP32-S3R2 and SX-1262 chipsets, but removes the CP2102 serial port chip. It features a 0.96 -inch display with a fully protected design, making it ideal for displaying debugging information and battery status. It also includes 2MP of internal SRAM and 16MB of external SRAM. The flash memory easily handles complex firmware. The high-power version of the LoRa system boasts an increased transmit power of 271dBm, ensuring stable communication. The GNSS interface consumes less than 20uA, maintaining its low-power design. The PC case fully encloses the screen and integrates a 2.4GH z antenna, enhancing overall strength and integration.
^^ Plug and Play: Easily charge via the Type-C port, which features integrated voltage regulation, ESD protection, and short-circuit protection. Alternatively, you can use the SH 1.25 -2P solar connector, which is compatible with solar panels up to 4.4 -6V/540mA. This innovative design ensures your WiFi LoRa 32 (V4) stays powered and ready for use. This ESP32 kit supports charge and discharge management, overcharge protection, battery level detection, and automatic USB/battery power switching, making it an ideal choice. ^^ Strong Compatibility and
Developer-Friendly Design: This ESP32 LoRa Arduino development board is compatible with Arduino. This development environment easily integrates with existing projects and compatible devices such as the Raspberry Pi. With 2MP of internal SRAM and 16MB of external Flash memory, it easily handles complex firmware and simplifies program downloading and debugging, making it an ideal choice for both new and experienced developers.
^^ Note: The securing screw in the upper left corner of the screen is a special plastic screw, unlike the other three. This screw prevents interference with the 2.4GH z radio frequency and is not a product defect. If you encounter a black screen or motherboard malfunction: This is because the stable system does not support firmware V4. You can try using version 2.7. 11 or 2.7. 12. Please flash the firmware first. This issue is most likely caused by flashing the wrong firmware.
^^ Note: Regarding firmware updates, the ESP32 requires the use of BOOT mode in some cases; this is a chip characteristic. This is mentioned in the FAQ on the official website and online documentation. Regarding the battery interface, it is a standard size. Meshtastic's 2.7. 12 Bluetooth connectivity had flaws; these issues have been fixed in 2.7. 13, which also removed power limitations in most regions. The downgraded version 2.7. 11 imposed numerous restrictions on RF power
