Review on π‘ 2 Pack DAOKI SI4463 HC-12 433MHz Wireless Serial Port Module with Antenna - Upgraded 1000M Range, Bluetooth Alternative by Santiago Serrano
Simple, efficient, flexible and affordable.
I used them to connect a pair of Arduinos that were previously wired together. Works impressively well. And no code changes were required! These devices act like a "wire" that requires no configuration or adding libraries to your code. Works perfectly!
- Supply voltage 3.2-5.5 V. (If the module is to be in the transmission state for a long time, it is recommended to connect a 1N4007 diode in series with a supply voltage of more than 4.5 V to prevent heating of the built-in module to avoid LDO module)
- Will be added later
