This is basically a single channel servo opto-coupler, but
you can add an extra one (yes two in total) using a “Y” cable on the output,
just to provide power to the servos. Click here for more details.
This opto-coupler is even more convenient and cheaper than
the old version I used to offer, because it works with less components and the
input part of the circuit is not required to add a power supply or extra
battery, in other words you can connect the input signals (PWM) directly to
your microcontroller or servo controller without an extra power supply, all included
in a super small and low profile board design.
We also offer an assembled version here.
