Taidacent Long Range Extender Micro Power TX/RX Device 433mhz RF Signal Repeater PT2262 Learning Code

hello in this video we'll talk about some radio  transmitters for you Arduino projects or even   raspberry or SBC's so this one here is the RF 22  it works at the same frequency as the wee-fee so   it's 2.4 gigahertz and it uses an SPI protocol  SPI stands for serial peripheral interface and   I will zoom a bit if you can read here sak M 1 M  0 etc there are the pins of the SPI so it needs   at least six pins plus two for the power here and  this has a range like 1900 meters you see that it   accelerates this antenna that we can the attached  with this connector so we could even put some   cable to put the antenna far away from the circuit  or in the top of the roof if we want to increase   the range from our home but this is not the sensor  or the radio transceiver I will talk about this   video the subject of this video are these two I  forgot to say these transmit and receive so if y
