* Available frequency version 315 / 433 / 390 / 418 MHZ, MOQ 50pcs for not listed version
* Sensitivity -110dBm, power consumption 2mA
* DO NOT forget to solder the antenna.

== EDRF2 Pin Definition ==
* D3~D0 default low, trigger to HIGH

== Paring ==
If transmitter has four buttons, it will match to EDRF2 Receiver:
* D0 -> Button A
* D1 -> Button B
* D2 -> Button C
* D3 -> Button D

== Use with ESP8266 ==
* EDRF2 D0 pin connects to ESP8266 IO0 pin, EDRF2 D0 remains high TTL level by default.
* Pair EDRF2 with your transmitter
* Press button A to trigger ESP8266 IO0 pin to low
* Software can detect the triggering timing of IO0 pin, or flip low or high level of IO0 pin.
