433M wireless ASK receiver module 3-5V receiver ultra-low power main feature 1, the industry's first high-Q dielectric resonator frequency stabilization technology to replace SAW resonator frequency stability of plus or minus 150KHZ. 2, super anti-interference ability of power supply, built-in ripple rejection circuit, switching power supply, power supply and other strong tube partial pressure ripple interference circuit stability, eliminating the need for three-terminal regulator IC thereby reducing costs. 3, wide supply voltage range (4.5-5.5V) and extremely low power consumption, specific power-saving mode, the typical power consumption of 1.4mA, for battery-powered devices. 4, stable and reliable, with a very wide operating temperature range. 5, with ultra-small size (12 * 18 * 2mm) ultra-thin thickness (2mm), the back of the module no device can be installed close to the board. 6, low radiation itself, through a variety of international testing standards. Performance Operating frequency: 315MHz (H5V3M) / 433MHz (H5V4N) Operating voltage: 5V (4.5-5.5V) ordinary super-regenerative receiver head must be a stable 5V supply even if the error would seriously affect the sensitivity of 0.1V Oh Operating Current: 1.8mA Modulation: ASK Sensitivity: - 105dBm (H5V3C / H5V4D as - 102dBm) Transfer rate: 4.8kbps Receive Bandwidth: 2MHz (6dB) Resistance pit antenna: 75 ohms Data output: standard compatible CMOS level Dimensions: 12 × 18 × 2mm [length × width × thickness] Operating temperature: -45 deg.] C ~ + 85 deg.] C (H5V3C / H5V4D of -40 ℃ ~ + 85 ℃) Pin Description 1.GND 2.3.DAT data output 4.VCC power 5.GND 6.ANT antenna pin pitch 2.54mm repeated simply connect a pin to Precautions 1, the data output is compatible with standard CMOS data output terminal pair, the power supply can not pull-up, pull-down resistors and capacitors, should be connected directly to the output data and the decoded input. Otherwise, both increased costs and affect the results. 2, the signal is too strong when the receiving module will be blocked is like, the above recommendations 10CM remote control module from the antenna. 3, the antenna is very important for the wireless receiver module, the antenna is not connected or incorrect use can affect antenna reception, wireless receiver modules generally use two antennas: Item 1: 0.5 ~ 1mm in diameter straight wire or cord as an antenna, 433.92MHz correspond 17CM long, 315MHz correspond 23CM long, should pay attention to when using this antenna as much as possible and to expand the antenna away from metal bodies. This antenna low price good effect No. 2: Use the helical antenna, a small volume of this antenna is easy to install antenna copper core with a diameter of 0.5cm single strand of wire production, pay attention when installing the antenna away from the circuit board and receiver module 5 ~ 10MM or more, otherwise it will affect the reception. To get the best results, this antenna is less effective, but the volume is small. If necessary, please click: 315 / 433MHz antenna spring / helical antenna / coil antenna / built-in antenna transmit / receive antenna This module can be installed vertically on the circuit board, which means that the trough module inserted in the slot weld, due to the back of the module components can not close the back board flat installation. Not open trough can also add pins to use welding 4P (super-regenerative common pinout and consistent) Installation should avoid metal body placed in the top 5mm of the module, otherwise it will affect the results. Do not apply excessive voltage, when the soldering iron should be grounded prevent damage.
