Power Module

Product detailed description

The Power Module allows you to connect a 5 V DC power adapter via a standard 2.1 mm power jack socket. It features a high-current relay (230 V AC / 16 A) to control your appliances. Also you can drive a digital LED strip with it (compatible with WS2812B).

This module can power a TOWER node thanks to its integrated LDO regulator. The LDO generates 3.3 V output from the 5 V input.

Reliability is important - that’s why we have implemented a smart overvoltage, undervoltage and reverse polarity protection on the power jack input. This feature guarantees the input voltage range to always stay within the proper limits.

There are also two 5-pin sockets available. These make it possible to connect TOWER tags.
