TTGO - BLUE SCREEN OLED LORA 32, 868/915MHZ, ESP32, 0,96", BLUETOOTH, WIFI

Product introduction:
The product communicates using LoRa wireless, frequency 868MHz/915MHz (by programming firmware, hardware products, frequency change by product software CODE PROGRAMMING), the product is a signal transmitting and receiving device, a device is the default device (because the transmitter power-on display will be on, the received power-on needs to receive the LoRa signal to turn on the screen, so that the customer can detect whether the product is available.
This product is the same as 433MHz, but the frequency is high, and the product construction and antenna use are different.
Main features:
• This product is based on ESP32 WIFI upgraded SX1276 OLED chip, namely LoRa remote modem, frequency 868/915MHz, high sensitivity about -148dBm, +20dBm output power, high reliability,. Long transmission distance.
• Built-in 32MB flash WiFi antenna, 0.96 inch blue OLED display, lithium battery charging circuit, CP2102 interface and USB serial chip, perfect support for Arduino development environment,. It can be used for program inspection and product development, very convenient and fast.

Product specifications:
• Operating voltage: 3.3-7V
• Operating temperature range: -40 to 90°C
• Supports Sniffer, Station, SoftAP and WiFi direct mode software protocol analysis.
• Data rate: 150 Mbps for 11n HT40, 72 Mbps for 11n HT20, 54 Mbps for 11g and 11 Mbps for 11b
• Transmission power: 19.5 dBm at 11.5 dB, 16.5 dBm at 11g and 15.5 dBm at 11n
• Receiver sensitivity up to -98 dBm
UDP continuous throughput: 135 Mbps
Lithium battery charge and discharge circuit, when the battery is full, the blue LED will stop working. Please pay attention to the positive and negative poles of the battery when you use it, otherwise it will be damaged.
With the IO port touch screen signal input, you need to add a 100nF pull-up capacitor to this pin!
