HiLetgo HC-12 433Mhz SI4463/SI4438 Wireless Serial Port Module 1000M Replace Bluetooth with Antenna

hello then looks here from how to onyx calm in this Arduino tutorial we will learn how to use the HTF wireless serial communication module which is capable of making a long-range wireless communication between multiple Arduino boards with distances up to 1.8 kilometers for this tutorial I made two basic examples explaining how to connect the HC 12 module and make a basic communication between 2 or 3 nodes and an additional example we're using an accelerometer sensor at the first arduino i wirelessly control the position of a stepper motor at the 2nd arduino so first let's take a closer look at the 85th vial a serial port communication module is wireless working frequency band is from 430 2.4 megahertz to 473 megahertz and it has a total of 100 channels with a taping of 400 kilo hertz between each channel the transmitting power is from minus 1 to 20 decibel millivolts while the receiving
