  • Happymodel 2.4GHz ELRS Nano series receiver is based on ExpressLRS open source architecture and program, features ESP8285 MCU. Therefore, you can upgrade the firmware via WIFI, which is very user-friendly.
  • To flash the firmware, Power up the receiver while keeping the transmitter turned off. After a while, you can find the ExpressLRS hotspot. Connect to this hotspot using a PC or mobile phone. The password is expresslrs, then you can visit 10.0.0.1 to upload the firmware
  • Low latency and high refresh rate makes it very suitable for FPV racing and long range FPV cruising while being ultra-light and ultra-small, making them very suitable for Tinywhoop.
  • With this tiny teeny receiver you can achieve great range even comparable to crossfire or Tracer, ghost. Don't just take my word for it, search Crossfire vs expresslrs on youtube and hear what Joshua Bardwell has to say.
  • Weight: 0.41g (without antenna), Package includes: 1x HappyModel 2.4GHz EP1 TCXO RX Express LRS Receiver, 2x Antennas

Very good product and great option for micro elrs receiver. I have them on a few of my micros and they work great. Better range than an ep2.
