The PCB layout has changed for an improvement in WiFi radio performance | 1MB Flash Memory | About program: Please choose "Generic ESP8285 Module" board in Arduino IDE to program it. | What You Get: 1 X ESP8266 esp-01s Module.
WiFi LoRa 32 is a classic IoT dev-board. The newly launched V3 version retains Wi-Fi, BLE, LoRa, OLED display, and other functions | MCU: ESP32-S3FN8 (V2 is ESP32-D0WDQ6), LoRa Chip: SX1262(V2 is SX1276/8), USB Socket: Type-C(V2 is Micro-USB) | The MCU is different, so the definitions of V2 and V3 GPIO pins are different | Upgraded V3 version has better impedance matching of RF circuits | When you use esp32 oled lora, you need to use 2pcs together. One is used for receiving and another for sending | It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers | What you will get: 2 X ESP32 Lora V3 development board + 2 X 915MHz Antenna + 2 X JST 1.25mm-2P Connector cable + 2.54 pin (no welding) + 2 X Protective Case for lora board
Cable length:14cm | If you have a U.FL connector (the ity bity one) then use the cable, else the next most popular is the full size SMA connector in which case the 3DBI Antenna will screw on directly. | Extended range 3BI Adjustable WiFi Antenna with gold plated U.FL to Female SMA connection cable. | If you are looking for extended WiFi range from your ESP8266, CC3000 or other WiFi based projects, then this Antenna package is what you need. | What You Get: 2 X 3DBI WiFi Antenna, 2 X U.FL to Female SMA Cable.
