From BATC Wiki

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.


All the project documentation is available for download in the zip file:

Colin G4KLB has done an excellent video on constructing the MiniTiouner:

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 has only sold a NIM from Serit. However, as the pinout is different from the Sharp NIM, a simple adapter board is required 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 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. Any new constructors should use the version 2 board which will not need the adapter PCB.

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:

Compatible NIM types

Only NIMs ( Network Interface Module) or tuners that have the following STMicroelectronics chips can be used:

  • Zero tuner chip can be STB6100, STV6110, STV6111, STV6120
  • Demodulator chip STV0903, STV0913, STV0910

The following NIMs can be used:

  • Eardatek EDS-4B47FF1B+ (sold by BATC shop during 2015 / 16)
  • Sharp F7VZ0169 (sold by BATC shop during 2016)
  • Samsung DNBU10711IST
  • Samsung DNBU10512IST
  • LG TDQX-S001F
  • Serit SP2246
  • Serit FTS-4335 - Sold by BATC shop in 2017 but with different pin out so needs the adapter card.
