WiFi LoRa 32 V4 ESP32-S3 SX1262 Solar Dev Board Meshtastic

WiFi LoRa 32 V4 — Solar-Powered ESP32-S3 Development Board for Mesh Networks

The WiFi LoRa 32 V4 is the fully upgraded evolution of the classic LoRa development board, built on the powerful ESP32-S3R2 MCU and SX1262 LoRa transceiver. With tri-mode wireless connectivity (Wi-Fi, BLE, and LoRa), solar charging support, and an ultra-low standby current under 20μA, this board is engineered for professional IoT deployments — from smart cities and agricultural monitoring to Meshtastic mesh networking and off-grid remote sensing.

Made in Mainland China.

Key Features

• Triple Wireless Connectivity: Wi-Fi 802.11 b/g/n, Bluetooth Low Energy (BLE), and LoRa (863–928 MHz) all in one board.
• High-Power LoRa TX: Up to 28 ±1 dBm transmit power (high-power version) or 22 dBm (low-power version) for long-range communication.
• Solar Input Ready: Dedicated SH1.25-2Pin solar panel interface enables off-grid, self-sustaining deployments.
• Generous Memory: 2MB PSRAM + 16MB external Flash — ideal for complex UIs and data-heavy applications.
• GNSS Interface: SH1.25-8Pin GPS/GNSS connector for location-aware IoT projects.
• Ultra-Low Power: Standby current under 20μA keeps battery-operated nodes running longer.
• 0.96-Inch OLED Display: Onboard screen with full mechanical protection and B2B connector.
• Gold-Plated Pins: 40-pin header with gold-plated contacts for reliable, corrosion-resistant connections.
• FPC 2.4G Antenna: Integrated PC casing that protects the screen and houses the FPC 2.4G antenna.
• V3-Compatible Form Factor: Pin and footprint compatibility with WiFi LoRa 32 V3 for easy upgrades.
• Meshtastic Ready: Fully compatible with the Meshtastic open-source mesh networking firmware.
