A breadboard adapter for the GR10J Numicator (Nixie). These tubes have 1mm pins that plug in to a socket. This board is intended to use female D-SUB pins as a ‘socket’. These are often listed on eBay as ‘1mm tube socket pins’.

The board includes pads for a neopixel and for a current limiting resistor (or a jumper if current is limited off-board). Adding the resistor on the board allows you to easily swap different adapter boards in and out without having to worry about changing this resistor.

See my web site for a complete list of all my Nixie tube adapters.
