برد توسعه ESP32 دارای نمایشگر OLED و چیپ SX1278

ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC ultra-low-power 40 nm technology. It is designed to achieve the best power and RF performance, showing robustness, versatility and reliability in a wide variety of applications and power scenarios. The ESP32 has built-in support for Wifi and Bluetooth communication but not for LoRa. A SX127x or RFM9x LoRa transceiver adds support for LoRa and the LoRaWAN protocol that are needed for The Things Network. Semtech SX127x LoRa transceivers and HopeRF RFM9x LoRa transceivers are identical. They come in different variants, depending on the targeted frequency band (433 MHz). Which frequencies are used depends on the geographic region and local ISM band regulations. This product is based on the WIFI Kit 32 added SX1278 chip, that is, LoRa ™ remote modem, 433MHz frequency, about -148dBm high sensitivity, +20 dBm power output, high reliability, transmission distance (measured open area communication distance 2.6Km).
