Description <br> 1. The upgraded model has a built-in SX1262 + ESP32 chip and fully supports the IoT development kit of the standard LoRaWAN protocol. <br> 2. Products can be programmed through standard libraries and concise development languages to quickly complete solution verification and product development. <br> 3. Three major wireless communication protocols, ESP32 chip, supports WIFI, BLE, and LoRa wireless communication functions. <br> 4. With shielding cover, strong anti-interference, the shielding cover is installed on the module, which greatly improves the products anti-interference ability. <br> 5. The Type-C USB interface has complete voltage regulator, ESD protection, short circuit protection, radio frequency shielding and other protection measures. <br> <br> Applicable to various intelligent scenarios, it can be used as a gateway for IoT products and as a driver for terminal products. <br> MCU chip:ESP32-S3FN8 (Xtensa 32-bit lx7 dual-core processor) <br> Main frequency:240 MHz maximum <br> LORA chip:SX1262 <br> USB to serial port chip:CP2102 <br> Maximum receiving sensitivity:-139dBmLORA <br> Maximum output power:211dBm <br> :7xADC1; 9xADC2; 8xTouch; 3xUART; 2xI2C; 2xSPI <br> FLASH:8MB <br> Wi-Fi:802.11 b/g, up to 150Mbps <br> Interface:Type-C; battery interface; LORA antenna interface; <br> OLED screen:0.49 inches <br> Battery type:supports 3.7v lithium battery charging and discharging <br> Sleep current:Less than 10 <br> Working temperature:-20-70 <br> Due to different product batches, the appearance may be different, which does not affect use. <br> Frequency:433-510MHz <br> Colour:Black <br> Material:PC+Metal <br> Size:58.08x22.6x8.2mm <br> <br> Package Contents: <br> 1 x development board <br> 1 x antenna <br> 1 x battery cable <br> 2 x pin header <br> <br> Only the above package content, other products are not included. <br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
