Ils - TTGO LORA32 868/915Mhz SX1276 ESP32 OLED-Display Bluetooth WiFi LoraElektronik
Description: The 8685 M Hz antenna needs to be in connection with the I P E X interface (if the antenna is not connected, it may damage the Lo Ra chip) Lithium battery charge and discharge circuit, when the battery is full, the blue L E D will stop working. When using, pay attention to the positive and negative of the battery, otherwise it will be damaged! With I O port touch screen touch signal input, you need to add the 100n F pull-down capacitor to this pin! Example: This product is a S X1276 chip based on E S P32 W I F I increased O L E D, namely Lo Ra remote modem, 8685 M Hz frequency, high sensitivity is over-148d Bm, + 20d Bm output power, high reliability, long transmission distance. the onboard 32 M B Flash wi-fi antenna, 0 inch blue oled display, lithium battery charging circuit, C P2102 interface and U S B 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. 3 V to 7 V Operating temperature range: -40 ° C to + ° C Support for Sniffer software protocol analysis, Station, Soft A P, and Wi-Fi Direct modes Data rates: 150 Mbps @ 11n H T40. , 72 Mbps @ 11n H T20, 54 Mbps @ 11g, 11 Mbps @ 11btransmit power: 5 d Bm @ 11b, 16. 5 d Bm @ 11g, 15. 5 d Bm @ 11nreceiver sensitivity up to d Bm U D P sustained throughput of 135 Mbps Pin diagram: Test details: Use legend: For example One(1) 868mhz /5 Mhz O L E D Lo Ra Sender#include #include #include #include " S S D1306. h"#include "images. h"#define S C K 5 // G P I O5 - S X1278s S C K#define M I S O // G P I O- S X1278s M I S O#define M O S I 27 // G P I O27 - S X1278s M O S I#define S S 18 // G P I O18 - S X1278s C S#define R S T 14 // G P I O14 - S X1278s R E S E T#define D I0 26 // G P I O26 - S X1278s I R Q (interrupt request)#define B A N D 868 E6 //5 E6unsigned int coun
