STM32F103 C8T6 3.3V meets 170Volt Neons. ... Part 001

Over the last few months these "Coloured Neon lamp indicators" have been popping up on the matrix, so I could not resit...well who could not resist mixing 3.3volt logic with 170volt.

They come in a variety of colours "Green","Blue" and "Orange" , the glow intensity is good even in daylight.

The MCU you see above is know as the "Blue-Pill" , it belongs to the STM32 family.

To put it in simple terms.... its a bit like an Arduino on steroids.
