Meshnology ESP32 LoRa V4 Development Board +GPS Version + 2800 Battery + Touch Screen Case Carrying ESP32-S3R2 SX1262 With 915 MHz Whip Antenna WiFi Bluetooth V4 Expansion Kit for Ar duino LoRawan IOT

V4 Development Board
Expansion Kit: This ready-to-use LoRa 32 V4 development board expansion kit requires no installation and is plug-and-play. While retaining the powerful core functions of its predecessor, it features comprehensive optimizations in hardware design, power management, and scalability, significantly enhancing the development experience. The kit includes a built-in touchscreen for real-time monitoring and convenient control of sensor data; a standard soft whip antenna to enhance LoRa gain and expand application range; and an integrated L76K GNSS module for precise positioning, perfectly adapting to various IoT ^^
Strong Connectivity: Our development board is equipped with a dedicated soft whip antenna, and the reserved LoRa U. FL interface ensures stable, long-range wireless communication. The newly added SH 1.25 -8 pin GPS interface facilitates the expansion of positioning functions. In addition, it has a rich set of external interfaces. The size and pin arrangement of this development board are compatible with LoRa 32 V2 and V3 versions, and the additional external pins enhance its scalability.
^^ Upgraded Development Board: ESP32-S3 and LoRa SX1262, More Powerful, Longer
Range: Utilizing the latest ESP32-S3R2 with 2MB PSRAM and 16MB Flash, paired with the Semtech SX1262, it achieves high-power LoRa transmission of 27dBm. It supports ultra-low power 20A sleep mode and integrated solar charging, and features a 2800mAh Li-ion battery, making it ideal for long-term battery-powered Meshtastic and LoRaWAN applications.
^^ Rugged Housing: The housing features a touchscreen front panel, aluminum side panels, and a polycarbonate back cover. Equipped with professional ports and an expandable B2B interface, including a built-in SMA antenna port, button interface, and B2B female expansion socket, it seamlessly connects to multiple external sensors and peripherals for customized IoT setups, making it a favorite among developers. ^^ Strong Compatibility and
Developer-Friendly Design: This ESP32 LoRa Arduino development board supports Arduino. The development environment can be easily integrated into existing projects and compatible devices such as the Raspberry Pi. With 2MP of internal SRAM and 16MB of external Flash, it can easily handle complex firmware and facilitate program download and debugging, making it ideal meshtastic devices for both novice and experienced developers.
^^ Note: V4 Board The screw securing the screen in the upper left corner is a special plastic screw, different from the other three screws. 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 failure: 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 problem is most likely caused by flashing the wrong firmware.
^^ Note: V4 Board Regarding firmware updates, the ESP32 requires BOOT mode in some cases; this is a characteristic of the chip. Instructions are available in the FAQ and online documentation on the official website. The battery interface is standard size. Meshtastic version 2.7. 12 had Bluetooth connectivity issues; these problems were fixed in version 2.7. 13, which also removed power limitations in most regions. The downgraded version 2.7. 11 imposed numerous limitations on RF power.
Note: Local maps require an SD card expansion. This expansion feature is still under development.
