Arduino fs1000a example5/28/2023 ![]() But well, their functionality is still limited. Of course, there are at least a couple of libraries for different microcontrollers (Arduino and similar) like VirtualWire or RadioHead. Everything above that has to be done in the software. They offer only basic functionality: receiver reports digital ONE when the transmitter detects ONE on the input (if in range, of course). They do not offer anything like error correction, RSSI, frequency hopping, or even two-directional transmission. A set of them (you will need one transmitter and one receiver) costs about $1. One of the cheapest (but not the best) solutions for DIY wireless data transmission between different devices (Arduino and other microcontrollers) is a pair of 433MHz modules: FS1000A and XY-MK-5V.
