• V4 Development Board: The LoRa 32 V4 is a brand-new upgraded version of 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. Suitable for IoT applications such as smart cities, agricultural monitoring, smart homes, industrial control, security systems, and wireless meter reading, it provides developers with a more efficient and flexible development experience.
• Powerful Connectivity: Our development board features dedicated 2.4GHz metal spring antennas and rubber stick antennas for Wi-Fi and Bluetooth, along with a reserved U.FL interface for LoRa, ensuring stable and long-range wireless communication. A new SH1.25-8-pin GPS interface facilitates positioning expansion. The board's form factor and pinout are compatible with the LoRa 32 V2 and V3 versions, while additional external pins enhance scalability.
• Hardware Upgrade: Our V4 development board is equipped with the ESP32-S3R2 and SX-1262 chipsets, a 0.96-inch display ideal for displaying debugging information and battery charge, 2MP internal SRAM, and an external 16MB SRAM. Flash memory can easily handle complex firmware. The high-power version of LoRa transmit power is increased to 27±1dBm, ensuring stable communication. Continuing its low-power design, the GNSS interface power is less than 20uA. The PC case fully surrounds the screen and integrates the 2.4GHz antenna, enhancing overall strength and integration.
• Perfectly compatible with V3 and V4 development boards: kit features a built-in 3000mAh battery and comes with a unique N39 protective case.case is compatible with both V3 and V4 development boards. You can easily charge it via a Type-C interface that integrates voltage regulation, ESD protection, and short-circuit protection. Additionally, you can use the SH1.25-2P solar connector, which is compatible with solar panels up to 4.4-6V/540mA. This innovative design ensures your WiFi LoRa 32 (V4) is always fully charged and ready to use. With its charge/discharge management, overcharge protection, battery level detection, and automatic USB/battery switching, this ESP32 kit is an ideal choice
• Strong compatibility and developer-friendly design: This ESP32 LoRa Ar duino development board supports Ar duino. The development environment can be easily integrated with existing projects and compatible devices such as for 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 an ideal choice for both novice 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 2.4GHz 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.
