A very simple IN-12B Nixie breakout board

Parts needed

• 11 MMBTA42 transistors
• 12 30kOhm 0603 (Imperial) SMD resistors
• 12 1mm socket pins (can be found on Ebay)
• Some standard header pins (2 for GND, 2 for HV-IN, 11 for inputs)

Usage

• Provide ~180V between HV-IN and GND
• turn on any digit with a 3.3V or 5V logic input on corresponding pin

Known issues

• the additional GND and HV-IN header pins (for daisy chaining) may be blocked by the Nixie itself
