Iused in combination with an Arduino for a remote semaphore project. It only works if you place a 10uF cap VERY close to the power input pins, but then it works great. It is fully compatible with the most popular RF24 libraries for arduino. very fast communication, I used to send a few bytes

Q:
whether this is original from nordicsemiconductor or chinese clone?

Good morning, I may have a trivial questio: is It possible to control six servos and two brushless motore with this transmitter module? How many devices can be controlled with it?

ithink the main limitation comes down to what you use to control the devices and how fast you need the devices to react. That being said there should be no problem what so ever with six servos and 2 brushless motor's. And you will need some sort of micro controller to receive the signal and translate it to your servos and motor's
