This is the bare PCB from my nixie power supply kit. It allows you to make a switchmode power supply to provide up to 180 volts for your nixie projects (or any other gas discharge tube that will strike with that voltage!) and will run from 9 to 12 VDC. Maximum output current is 10mA at 180 volts.
Drive nixie tubes and neon bulbs (not neon tubes though, which are different!)
This is the blank PCB only, no components are included!
