V4 Upgraded ESP32-S3 & LoRa SX1262 Development Board: Features the latest ESP32-S3R2 chip with 2MB PSRAM and 16MB Flash, delivering superior processing for complex IoT applications and Meshtastic projects. This major upgrade from V3 models provides enhanced performance for Meshtastic devices and LoRa development boards, ensuring smooth operation of advanced firmware—now in a more compact and cost-effective ESP32 development board without the integrated display.
High Power 27dBm Long-Range LoRa Radio Communication: Experience exceptional wireless range with 27dBm transmission power and -137dBm sensitivity. Perfect for building reliable Meshtastic nodes, expansive LoRa radio networks, smart home IoT devices, and industrial applications. This powerful LoRa module provides greater communication distance across large properties and urban environments, making it an ideal LoRa Meshtastic solution.
Compact & Cost-Effective LoRa Meshtastic Solution: This version removes the OLED display to offer a more compact form factor and better value, ideal for projects where a physical display is not required or for users who prefer custom external interfaces. The board still features a protective casing with FPC antenna for stable Wi-Fi/Bluetooth and an external antenna for enhanced LoRa performance, providing a flexible Meshtastic development board ready for deployment.
Advanced Power Management with Solar & GPS Connectivity: Designed for outdoor use with optimized battery management and ultra-low 20μA sleep current—achieving even better power efficiency without the display. Includes solar panel interface for building Meshtastic solar nodes and GNSS port for Meshtastic GPS applications. The Type-C interface with voltage regulation ensures reliable operation for asset tracking and remote monitoring projects.
