Details

Note that this PCB is now only available in strips of 11 boards. These can easilly be separated from each other, or used as is.

This is a tiny ancillary board that contains a single transistorized LED driver. It is designed to be connected to any output that puts out a voltage that ranges between 0V and over 2V. As presented in the diagrams, the module is designed for gate signals where the LED will have an ON/OFF action.

If the lower 100k resistor in the input divider is replaced with a reverse biased 1N4148 diode, the module can be used to monitor the positive excursions of bipolar CVs and audio signals.

It can also be connected to some internal circuit elements to indicate how that part of the circuit is behaving.

The drive current can be adjusted for different types of LEDs. If using super bright LEDs, increase the 1k resistor to 10k.
