Seller: flashshop1313 (3.965) 97.5%, Location: pechino, Ships to: Worldwide, Item: 192969781676 If you need the 915Mhz version, please buy Product ID: 1239769Description: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!Note:This product does not include the battery. 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 7VOperating temperature range: -40 ° C to + 90 ° CSupport for Sniffer software protocol analysis, Station, SoftAP, and Wi-Fi Direct modesData rates: 150 Mbps @ 11n HT40., 72 Mbps @ 11n HT20, 54 Mbps @ 11g, 11 Mbps @ 11btransmit power: 19.5 dBm @ 11b, 16.5 dBm @ 11g, 15.5 dBm @ 11nreceiver sensitivity up to -98 dBmUDP sustained throughput of 135 MbpsPin diagram: Test details: Use legend: For example One: (1) 868mhzMhzOLED LoRaSender#include #include #include #include "SSD1306.h"#include "images.h"#define SCK 5 // GPIO5 - SX1278s SCK#define MISO 19 // GPIO19 - SX1278s MISO#define MOSI 27 // GPIO27 - SX1278s MOSI#define SS 18 // GPIO18 - SX1278s CS#define RST 14 // GPIO14 - SX1278s RESET#define DI0 26 // GPIO26 - SX1278s IRQ (interrupt request)#define BAND 868E6 // 915E6unsigned 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 (!
