I received my board order about a week ago and all is well with the new boards for the TIU Signal Tester. I have built several of the new boards and they work just as expected. Boards and chips are now ready to ship for anyone interested.
Here is pricing:
Bare board only: $1.60 each
Board with SOIC chip loose $2.50 each
Board with chip installed $3.50 each
Your final costs should be about $8.00 per board. One board works for two TIU ports; you will need two boards to cover all 4 TIU ports.
The chip is smd with small leads @ 1.27mm pitch; this is why I am offering to install it for a nominal installation cost (for anyone who may not be comfortable with this kind of soldering). All the other board components are easy thru-hole stuff. Shipping will be extra; please send me your mailing address so I can get that figured out.
I have attached comprehensive User Notes below which will guide you through board assembly and installation process. Also included is a BOM for ordering the additional parts needed, and a 3D board view. These new boards are smaller than the original prototype and fit into the TIU easily. Also included is a case hole drilling template to make that part easy.
The gerber files are also included for anyone who wants to go at it themselves.
Have fun, Rod
