“Hello, I am pleased to present to you my first major project, a custom designed 7 channel transceiver unit. The transmitter is based on an arduino nano, to which two joysticks are connected, a potmeter and two toggle switches. Communication is handled by the nRF24L01. I chose this module because it is relatively cheap, has a very long range when used properly and a very low latency. My main principles in building it were cheapness and to create a compact, good looking and reliable device. I didn’t want any disturbing long cables that could come loose during testing and cause malfunction, so I also designed my own PCB.
