2Pcs ESP32 LoRa V4 Development Board +GPS Version +3000mAh Battery + Case Carrying ESP32-S3R2 SX1262 With 915 MHz Antenna WiFi Bluetooth 0.96 OLED LoRa V4 Devices for Ar duino LoRawan IOT (N39 Green)

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 is equipped with dedicated 2.4GH z metal spring antennas and rubber rod antennas for Wi-Fi and Bluetooth and a reserved LoRa U. FL interface ensures stable long-range wireless communication. A new SH 1.25 -8-pin GPS interface facilitates positioning expansion. It also features a rich set of peripheral interfaces. The development board's form factor and pinout are compatible with LoRa 32 V2 and V3 versions and additional external pins enhance scalability.
Hardware Upgrade: Our V4 development board utilizes the ESP32-S3R2 and SX-1262 chipsets but removes the CP2102 serial port chip. It features a 0.96 -inch display with a fully protected screen structure ideal for displaying debugging information and battery status. It also includes 2MP of internal SRAM and 16MB of external SRAM. The flash memory easily handles complex firmware. The high-power version of the LoRa system boasts an increased transmit power of 27±1dBm ensuring stable communication. The GNSS interface consumes less than 20uA maintaining its low-power design. The PC case fully encloses the screen and integrates a 2.4GH z 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 SH 1.25 -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 choiceStrong 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 meshtastic devices 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 2.4GH z 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.
