The TinyIO Controller Board is a low cost I/O board that can be left in projects once they are completed.
It exposes 3 INPUT pins, a PWM pin also connected to an on-board LED and 1 OUTPUT pin, connected to a transistor with a snubbing diode.
A 500mA 5V regluator supplies power, with an input range of 6V to 35V. There is an on-board bridge rectifier, allowing AC input voltage.
This board has been manufactured and is available for purchase.
