Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at a detailed Introduction to HC-12. It is a wireless data transmitter and receiver module, that uses 433 megahertz frequency and can communicate to one thousand meter distance. It can communicate with more than one microcontroller. This module operates from 3.2 volts to 5.5 volts.
This Bluetooth module is installed in industries to control different processes and machines. It is also used in the circuitry of different security systems. This module uses silicons LABs Si4463 for (radio-frequency) RF data transmission. In today's post, we will look at its working, features, pinout and applications in detail. So let's get started with Introduction to HC-12.
Pin# | Type | Parameters |
Pin#1 | Vcc | At this pin input supply is provided to this module, the range of direct current source is 3.2 volts to 5.5 volts, and the load connected with it should be two hundred milliamperes. One thing you should keep in mind that when this module sending data tries to connect 1N4007 diode in series voltage source if its value is larger than 4.5 volts for reduction of heating. |
Pin#2 | GND | This pinout is connected with the ground. |
Pin#3 | RXD | It is UART (Universal Asynchronous Receiver/Transmitter) input data and TTL (Transistor-Transistor Logic) pinout. The resistance of one kilo is linked in series within the module. |
Pin#4 | TXD | it is UART (Universal Asynchronous Receiver/Transmitter) output data and TTL (Transistor-Transistor Logic) pinout. With this pinout, one-kilo ohm resistance is connected in series. |
Pin#5 | SET | This pinout is for the setting of different parameters at active low level. One kilo ohm resistance is also connected with it in series. |
Pin#6 | ANT | This pinout is for 433 megahertz antenna. |
Pin#7 | GND | it is the ground pinout. |
Pin#8 | GND | This pinout is also connected with the ground. |
Pin#9 | NC | It is not used for any connection. |
ANT1 | ANT | It is IPEX20279-001E-03 antenna socket. |
ANT2 | ANT | 433MHz spring antenna solder eyelet. |
That is a complete article on HC-12 I have mentioned each and everything related to HC-12 in this post if you have any questions ask in the comments. Thanks for reading.
