I use this board to control a Raspberry Pi (old model) my exterior blinds on InterTechno actuators (the old with adjusting switches). You have on the board only one wire as an antenna solder (17 cm at 433 MHz) and some tinkering with the software on
After the component has been found all the way from China to me it works just fine with a Rasberry Pi. The range is (without antenna) surprisingly well (by a ceiling over 10m). Am satisfied.
17cm insulated leads soldered to the antenna connection, connected module on Arduino, program code (from the Internet) generated and could immediately switch my ELRO radio outlets.
