Receiver Board ATAB5282

An LF wake-up demonstration can alternatively be performed with the 3D receiver ATA5282.

Due to the header detection, the Q-factor of the antenna module has to be reduced to Q < 20
(for example, RANT = 15).

The board is equipped with a 3D LF antenna. It offers the possibility of an optional assembly by
separate antenna coils for x, y, and z field detection. Additionally, an LED is used to indicate the
received data protocol. Test points and a pin socket allow the measurement of all relevant sig-
nals. A 3V lithium battery is used, supplying the receiver with LED indication.
