DollaTek 868/915MHZ ESP32 wireless shell SX1276 LoRaWAN WIFI BLE module with 868MHZ anntenna for Arduino

• The main control chip uses ESP32-based ESP32-PICO-D4 module (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276/SX1278;
• Integrate WiFi, LoRa, and Bluetooth network connections, and reserve two IPEX (U.FL) interfaces for LoRa and 2.4GHz RF signals.
• Support the Arduino development environment;
• The module has good RF circuit design and low power consumption design (sleep current ≤ 30uA), which is convenient for IoT application vendors to quickly verify solutions and deploy applications;
• Pin: 1.27mm pitch stamp hole
