For another option, I am just starting to work with the HV507, 64 channel 300V. You can get them for $4.40 a piece on aliexpress.

Thanks for the quick reply, Grahame. I will be driving mine from a PIC. I might do a layout which has the PIC on the board, but only populate one of the boards with the PIC. using these devices sure reduces the number of IOs needed.

I just wondered if anyone else had used these devices and if so, were there any issues? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
