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.
Not tested yet. Looks good. One pin strip came loose. I will try it after soldering it. But I'm waiting others pieces to accomplish my project... If in troubles, I will call help center banggood.
The PCB seems very good. You have to work on PCA9685 datasheet to work with it.
The board quality is excellent. I try it with the Adafruit Servo PWM library and it is working perfectly with SDA and SCL connected to A4-A5 on Arduino Uno. Thank you Banggood.
Need to add power FET to each channel, increase load capacity, but after that, can be used to control 16x power LEDs with a pwm-signal, using only signel i2C SDA/SCL data lines!
Good product. Arrived on time
Excellent product, works fine with SG90 servo motor. Using Adafruit library.
Nice build ! All connectors come with the board. Bought to use it in a DIY music project
Saw this on many You Tube videos and seems to work great. Recommended.
