Electrical Requirements

Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating section may cause permanent damage. These are stress ratings only. Operating the module at these or any conditions other than those specified in the Operating Conditions sections of the specification should be avoided. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

The operating condition range defines those limits within which the functionality of the device is guaranteed. Where application information is given, it is advisory only and does not form part of the specification.

Absolute Maximum Rating

The limiting values given below are following the Absolute Maximum Rating System (IEC 134).

SYMBOL	DESCRIPTION	CONDITION	MIN	MAX
3.3Vaux	Module supply voltage	Input DC voltage at 3.3Vaux pins	-0.3 V	3.6 V
USB	USB D+/D- pins	Input DC voltage at USB interface pins		3.6 V
RESET	RAK5146 reset input	Input DC voltage at RESET input pin	-0.3 V	3.6 V
SPI	SPI interface	Input DC voltage at SPI interface pin	-0.3 V	3.6 V
