About :

There are a lot of instructions on the Internet on how to use ExpressLRS receivers and transmitters. How to connect them, how to configure, bind... But there is almost no information on how it works. So I decided to fill this gap and understand the details. Principles, nuances, how certain aspects of implementation affect the behavior. In particular, why and how do Serial ELRS, vs SPI ELRS, expressLRS 2 vs 3 differ, etc. 00:00 - intro 01:36 - what is ELRS, requirements, ideology 07:50 - LoRa modulation and signal physics. Problems solved by the LoRa protocol. Features of ELRS caused by the specifics of LoRa 22:53 - packet format and what it affects 38:06 - Hybrid, Wide, and other packet formats, their differences 45:11 - Telemetry 51:21 - the difference between ELRS v2 & v3 52:18 - pairing phrase, collision resolution 01:07:54 - hardware. The difference between SPI, serial ELRS 01:21:01 - a few words in conclusions our chat in Telegram https://t.me/petrokeyfpv/102325 Editing and all-effects in the video - @mrBububu my website https://peterokeyfpv.tilda.ws/ #fpv #elrs #expresslrs say thanks - crypto wallet USDT TRC20: TJh6rDWQkZt7CNxHo9MyMruNiKVEnAi93h
