This “transceiver” is surprisingly very small, only $ 0.99 at the time of writing, delivery if I'm not mistaken is free, the reviews are pretty positive, so order without fear. If you have any questions, just write to the seller of the goods.
Personally, I wanted to order this module for connecting two Arduinoks to myself, to make something like a robot that would move from the horizontal position of the accelerometer, which in turn would be on the glove in a fixed state, and the glove would be worn on the hand, this would be quite spectacularly. But unfortunately I didn’t do it. But I think you can make this not very difficult homemade)
This module has the following characteristics:
- Built-in 2.4 GHz antenna, supports up to six data channels
- Module size: 15 x 29 mm (including antenna)
- the module has a rather low operating voltage: 1.9-3.6 V
- The maximum data transfer rate using such a module is as much as 2 Mbit per second, which is very, very not bad for data sizes and current consumption.
This module also has an automatic power consumption mode, which is very useful in projects with a weak battery, or in projects that have to work for a very long time in standby mode for actions or signals, by the way, Arduino itself also has such a function, you can activate it using making changes to the program code of the sketch, on the Internet there is a lot of information on this topic.
Well, thank you all for your attention and good luck in future projects, friends!
