#291 External antennas and ESP32 Long-Range mode

Video Description

Everybody talks about LoRa to bridge long distances. Today we will have a look into how we can extend the range of a normal ESP32 with the Arduino IDE. You will also learn how to do that and stay legal. And maybe we even can reduce the power consumption of the chip if we do not need the extended range. And what we learn, we can also be used for our ordinary Wi-Fi network. Unfortunately, it does not work with the ESP8266. I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, and others. In this and the next video, we will: - Understand the basics of antennas for wireless transmission. If you are not interested in that, you find a link to the more hands-on part of the video in the description. - Introduce the new Long-Range mode for the ESP32 invented by Espressif - See how we can attach external antennas to ESP32 modules - Find an easy way to compare Wi-Fi antennas - Compare the performance of some typical antennas. Commercially available and home-made - Reduce the TX power of the ESP32 to stay legal and check its effect on overall power consumption Links: The project used for my tests: https://github.com/jnogues/ESP32-Long-Range-WiFi TTGO Mini with antenna connector: http://s.click.aliexpress.com/e/O3rUtCA4 or http://bit.ly/2ohsawD TTGO with changeable resistor: http://s.click.aliexpress.com/e/nl3RC6Ek Boards with only an antenna connector: https://www.ezsbc.com/index.php/featured-products-list-home-page/wifi01u.html Panel antenna: https://ebay.to/2Mc5Jks #ESP32 #WiFi #antenna Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess My Bitcoin address: 19FSmqbBzb5zsYB1d8Bq4KbxVmezToDNTV If you want to support the channel, please use the links below to start your shopping.
