Работает без проблем. Если использовать много приводов, то надо подобрать конденсатор (в комплекте не идет). Извините за неважную пайку - только учусь.
By far the best way to drive multiple servos - microcontrollers simply can't generate enough independent PWM signals accurately enough and with the required repitition rate. Had a handful of servos all gyrating independently very quickly. Beware of the need to set the limit values in the standard Arduino Adafruit examples or the servos will hard wall against their endstops and pull around 500mA each - not good for the servos, 9685 or power supply (mine set to 160 & 450). 60+ pins to solder but I perfer that to getting modules with pins bent in shipping. Since the I/O pins are the same at both ends (allows for cascading) I suggest mounting a female header at the other end to allow more flexible connecting.
