FS1000A

Small RF ASK Sender Available in 433MHz (Europe) and 315MHz (US)

This sender breakout board enables you to send data on the designated frequency. It typically comes as a kit together with the ASK receiver board MX-RM-5V.

Make sure you purchase the version for the frequency you intend to use. You cannot change the frequency later. In Europe, use the 433MHz version. The 315MHz version is intended for the US market. In Europe, 315MHz is reserved for military services, and you can get in serious trouble when you operate on this frequency.
