Description
If you need the 915MHz version, please click here to buy: Product ID 1507043 Description: The 868MHz antenna needs to be in connection with the IPEX interface (if the antenna is not connected, it may damage the LoRa chip) Lithium battery charge and discharge circuit, when the battery is full, the blue LED will stop working. When using, pay attention to the positive and negative of the battery, otherwise it will be damaged.With IO port touch screen touch signal input, you need to add the 100nF pull-down capacitor to this pin. Example: This product is a SX1276 chip based on ESP32 WIFI increased OLED, namely LoRa remote modem, 868MHz frequency, high sensitivity is over-148dBm, + 20dBm output power, high reliability, long transmission distance. the onboard 32MB Flash wi-fi antenna, 0.96 inch blue oled display, lithium battery charging circuit, CP2102 interface and USB serial chip, the perfect support for Arduino development environment, can be used for program checking and product development is very easy and fast. Operating voltage: 3.3V to 7V Operating temperature range: -40 C to + 90 C Support for Sniffer software protocol analysis, Station, SoftAP, and Wi-Fi Direct modes Data rates: 150 Mbps @ 11n HT40. 72 Mbps @ 11n HT20, 54 Mbps @ 11g, 11 Mbps @ 11b transmit power: 19.5 dBm @ 11b, 16.5 dBm @ 11g, 15.5 dBm @ 11n receiver sensitivity up to -98 dBm UDP sustained throughput of 135 Mbps Pin diagram: Test details: Use legend: Package included: 1 x Wemos TTGO LORA32 868Mhz SX1276 ESP32 1 x 868nhz Spring Antenna 1 x Line 2 x Pin For example One (1) 868mhzMhzOLED LoRaSender #include #include #include #include "SSD1306.h" #include "images.h" #define SCK 5 // GPIO5 - SX1278's SCK #define MISO 19 // GPIO19 - SX1278's MISO #define MOSI 27 // GPIO27 - SX1278's MOSI #define SS 18 // GPIO18 - SX1278's CS #define RST 14 // GPIO14 - SX1278's RESET #define DI0 26 // GPIO26 - SX1278's IRQ (interrupt request) #define BAND 868E6 // 915E6 unsigned int counter = 0; SSD1306 display (0x3c, 4, 15); String rssi = "RSSI -"; String packSize = "-"; String packet; void setup () { pinMode (16, OUTPUT); pinMode (2, OUTPUT); digitalWrite (16, LOW); // set GPIO16 low to reset OLED delay (50); digitalWrite (16, HIGH); // while OLED is running, GPIO16 must go high Serial.begin (9600); while (.
