Features of I2C 16-Channel Servo Driver:

1. micro: bit edge connector, directly pluggable
2. I2C controlled, using only 2 pins
3. Up to 16-Channel servo/PWM outputs, 12-bit resolution for each channel (4096 scales)
4. Integrates 5V regulator, up to 3A output current, can be powered from the battery through VIN terminal
5. Standard servo interface supports commonly used servo such as SG90, MG90S, MG996R, etc.
6. Reserved I2C control pins, allows working with other control boards
7. Comes with development resources and manual (micro: bit graphical examples like Bluetooth/2.4G wireless remote control)

Features :

1. PWM capability of up to 25 kHz combined with active freewheeling.
2. Switched mode current limitation for reduced power dissipation in overcurrent.
3. Status flag diagnosis with current sense capability.
4. Overtemperature shut down with latch behavior.
5. Overvoltage lockout.
6. Undervoltage shut down.
7. Driver circuit with logic level inputs.
8. Adjustable slew rates for optimized EMI.
9. 74AHC244 Schmitt-trigger Octal buffer/line driver for ESD protection (Inputs accepts voltages higher than VCC).

Input port:

1. RPWM: forward level or PWM signal input, active high.
2. LPWM: Reverse level or PWM signal input, active high.
3. R_EN: forward drive enable input, high-level enable, low level off.
4. L_EN: Reverse drive enable input, high-level enable, low level off.
5. R_IS: forward drive current alarm output.
6. L_IS: Reverse drive current alarm output.
7. VCC: +5 V power output, 5V power supply connection with the microcontroller.
8. GND: signal common low end.

Features:

5. Crossover current protection.
6. Thermal shutdown circuit.
7. Ground fault protection.
8. Loading and short circuit protection.
9. The optional five-step mode: full, 1/2, 1/4, 1/8 and 1/16.

Controller Board

1. Compact size, easy to install and use.
2. All jumpers hit the ON position to indicate 16 subdivisions (4988) or 32 subdivisions (8825).
3. Jm connection motor: Jv Connects 5V and 12V-24V Power Supply.
4. E /S /D /G of Jc corresponds to Enable /Step /Dir /Gnd driving signal output on the connection respectively.
