Voltage: DC5-10V power supply
16-Channel steering control
Size: 25×62 x15mm/1×2.4×0.6inch
PCA9685 chip is wrapped in the center of the board.
Power input terminal, green power indicator, reverse polarity protection input on the terminal block.
4 sets of 3-pin connectors make it easy to insert 16 servo motors at a time (the servo motor plug is slightly wider than 0.1″, so you can put 4 pairs of 0.1 connectors) .
Cascading design, placing a large capacitor on the V+ line, the maximum input voltage of the peripheral depends on the capacitance of 10V1000uf.
A 220 ohm series resistor is placed on all PWM output lines to protect and easily drive the LEDs.
