Features: The upgraded versionV3 has the same overall dimensionsas the old version, withhigher output power, theoretically longer transmission distance, and faster transmission rate. The LoRacrystal oscillator has been replaced with a temperature compensated crystal oscillator, which has stronge anti-interference performances. Lower power consumption (originally 800uA, now only around 10uA) and better performances. The new ESP32LoRa development board, which is lightweight and compact, has more advantages and has been optimized and upgraded in multiple aspects for better performances 240MHz main frequency FLASH 8Mbyte processor Xtensa 32-bit LX7 dualcore processor main control chip ESP32-S3FN8 LoRachip SX1262 Specifications: screen: 0.96'' OLED Main frequency 240MHz FLASH 8Mbyte Processor Xtensa 32-bit LX7 dualcore processor Main control chip ESP32-S3FN8 andLoRa Chip SX1262 Deep sleep less than10pA Open communication distance 2.8KM USB adapter chip Cp2102 Dualmodes Bluetoothcompatible Traditional Bluetoothcompatible and BLE Low Power Bluetoothcompatible Working voltage 3.3-7V Working temperature -20~70 Receiver sensitivity -139dbm (Sf12125KHz) SupportWIFI Bluetoothcompatible LoRaWan Applicable to: IoTs developers and electronics enthusiastsS Note: Due to the different monitorand light effect, the actual color of the item might be slightly different from the color showed on the pictures.
