LoRa Meshtastic ESP32 V4 Board with 868MHz Antenna and OLED Display AYWHP LoRa ESP32 Development Board Integrated WLAN Bluetooth SX-1262 Chip Compatible with Arduino/Meshtastic

Description:

The LoRa Meshtastic ESP32 V4 Board is a flagship development platform designed specifically for the Internet of Things, off-grid communications and remote monitoring. Based on the ESP32-S3 dual-core processor and Semtech SX1262 LoRa chip, it offers powerful computing power, LoRa communication with high transmission power of 27 dBm and a power consumption in deep sleep mode of less than 20 μA. The LoRa Meshtastic ESP32 V4 board has a built-in 3000 mAh lithium battery and supports charging via solar energy. Combined with a high-gain 868 MHz antenna, it is easy to build self-powered Meshtastic nodes, LoRaWAN gateways or sensor terminals with a range of several kilometres.

• Powerful: The ESP32-S3R2 dual-core processor combined with 2MB PSRAM and 16MB flash not only ensures smooth operation of the Meshtastic firmware, but also supports complex tasks such as web server, image processing and demanding user interfaces. It sets new standards in terms of performance among the LoRa development boards in its class.
• High performance: The LoRa Meshtastic ESP32 V4 board uses the SX1262 chip and is equipped with a power amplifier. With a transmission power of up to 27 dBm and an extremely high reception sensitivity of -137 dBm, it achieves a measured communication range of 5 to 10 kilometres in open ground, covering farms, school grounds or small communities effortlessly.
• Extremely long running time: thanks to the built-in 3000 mAh battery and solar charging circuit as well as a deep sleep mode with a power consumption of less than 20 μA, the board can be operated for several weeks even in persistent cloudy weather. In combination with the IP66 protected enclosure, it can be used on roofs, in treetops or at outdoor base stations to create a maintenance-free, off-grid communication network.
• Comprehensive functions: the integrated OLED display of the LoRa Meshtastic ESP32 V4 board displays the node ID, signal strength, battery charge as well as received and sent messages in real time, so that the status can be checked without a smartphone. The reserved 8-pin GNSS connector supports plug-and-play GPS modules and provides the hardware foundation for asset tracking, off-road location, and fleet management.
• Wide compatibility: The LoRa Meshtastic ESP32 V4 board is fully compatible with Meshtastic open source firmware and supports functions such as encrypted text communication, group chats, location sharing and remote monitoring. With the smartphone app (iOS/Android), nodes can be quickly configured and integrated into a decentralized mesh network to stay connected even in areas without cellular reception.
