MiniTiouner hardware Version 1
The original MiniTiouner hardware launched in 2015 used a PCB designed by Brian G4 EWJ to enable easy home construction of the MiniTiouner hardware and components for over 200 units have been sold around the world.

Colin G4KLB has done an excellent video on constructing the MiniTiouner: https://www.youtube.com/watch?v=vXUIQPeslwM
Compatible NIM
The version 1 PCB was designed for use with the Sharp and Edeartek tuner NIMs available from the BATC shop in 2015 and 2016.
Serit NIM Adapter card
Due to the Sharp NIM going obsolete, from Jan 2017 the BATC only sells a NIM from Serit. However as the pinout is different between the 2 units and Brian G4EWJ has designed a simple adapter board to enable the Serit NIM to be plugged in to the original MiniTiouner PCB.
Brian G4EWJ has designed a PCB and the blank board and the Serit FTS-4335V NIM is available in the BATC shop.
You only require the adaptor PCB if you are upgrading a MiniTiouner version 1 hardware to use the Serit tuner.
The adapter card build instructions, Parts List, Schematic and silkscreen print are in this zip file. NOTE - the kit referred to in the documentation is no longer available:
Note: As of April 2017 a new main PCB has been designed to directly take the Serit tuner - any new constructors should use this version 2 new board which will not need the adapter PCB.
