Hi,
I’m building a couple of emonTx boards and trying to source all the parts. My only doubt is the Mini-USB b socket.
Many thanks, Barry.

From memory I think they may be sourced from rapidonline perhaps @glyn.hudson ot @TrystanLea can confirm.
USB socket is Farnell: 565790511

Sorry for another dumb question but I’ve lost the emonTX V2 build guide… all links seem to take me back to the home page.
Can anyone point me in the right direction? I have all the parts and the Eagle files, just want to sanity-check before I start soldering.
Many thanks, Barry.
The emonTx V2 firmware, hardware design and build guide are all together in the emonTx V2 repo on github:

If you run into problems please post on the [Community Forum](https://community.openenergymonitor.org).
The PCB is built in an orderly sequence starting with the resistors and small components that are low on the board, then working up to the bulkier parts like connectors. After soldering each component, you need to cut off the excess component leg from the bottom using some cutters.
It is very easy to cause shorts which will make the board or specific parts of it not work, take your time during the build, be precise, use minimal solder and carefully check each joint after soldering it. If you suspect any short, check it with a multimeter and fix any shorts there and then, before continuing.

It's recommended you read through the whole of this guide and familiarise yourself with the steps before you start the actual build.
## Step 1 - Identify Components and Kit Contents
Lay out and identify the components from the kit.
