It is a of remote control wireless system developed based on the open source project ExpressLRS. The ELRS system has the characteristics of long remote control distance, stable connection, low latency, high refresh rate, flexible configuration, etcHigh-performance main control chip, using ESP8285 main control, higher computing powerTemperature compensated crystal oscillator, using TCXO temperature compensated crystal oscillator, no fear of extreme temperatures such as high temperature and low temperature affecting the working state. The frequency is more stable and the flight is The clock is more synchronized, using two channels to share a crystal oscillator, providing a more synchronized and stable clockIt has the advantage of stronger diffraction ability, can maintain better stability in an environment with dense obstacles, and is more suitable for long-distance navigationModel:ELRS 2.4GHz NANO RXName:ExpressLRS ReceiverFrequency:2.4GHzReturn power:100mwInput voltage:4V-5VAntenna connector:IPEX1The product appearance and printed words depending on the batch, but this does not affect use.Colour:As ShownMaterial:PCBPackage Contents:1 * ELRS 2.4GHz Nano Rx Receiver1 * Connecting Cable1 * 2.4GHz Dipole T-Antenna(The color is random, and the designation is not accepted)2 * Heat Shrink TubingOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
