SWE5 (v2) Information

This is documentation for the v2 SWE5, if you have a v1, click here.

This is a small module that allows you to use a USB power source to feed 5V into your 1-Wire network.

It simply consists of a USB socket, 2 pin screw terminal block, a jumper, two RJ45 sockets and an LED and resistor.

The PCB is 55x40mm. The RJ45 sockets overhang by around 1mm. The module is 20mm high. There are 3mm mounting holes 3mm in from each corner which gives them spacings of 49x34mm.

The power source can either be connected to the USB-B connector on the PCB or to the screw terminals. If you use a USB power source it can be a from spare USB port on your PC or USB hub, or a plug in USB power supply.

Simply connect your 1-Wire host adapter to the "IN" RJ45 socket and your network to the "OUT" RJ45 socket and all the devices on the "OUT" side will be fed with power on RJ45 pin 2 (as per our RJ45 wiring standard here).

If the jumper J1 is fitted power is also supplied to RJ45 pin 6, the "AUX 5V" line. None of our modules currently use this pin but it is included for compatibility with the common wiring standard.

Please note this only provides power on the 5V lines. At present this is all any of our modules need but some sold by other people require a 12V (or higher) supply on RJ45 pin 7 which this module does not provide.
