This is the H3V4F a module that tuned out of the box at 433 MHz RF popular in most remote switching. however there are 3 versions of H3VXX Module the 315Mhz and 433Mhz frequency, this devices has a  Bandwidth of 2Mhz -102dBm sensitivity at  4.8 kbps data rate max, and super heterodyne modulation runs at 2.4 ~ 4.2v typical operation for 3.3v , perfect device for RC projects, like remote control, home automations, alarm and security, anti-lost devices, RC Switch, Anti Thief devices. Etc. This module consist of RF IC’s featuring high sensitivity, low power consumption, perfect for battery operated RC devices and best replacement for traditional regenerative and heterodyne solutions. For more details please refer to the datasheet below.
