PCA9685, 16-channel servo motor controller, 12-bit PWM I2C, Adafruit 815

Все о продукте

The 16-channel PWM generator is useful when there is a shortage of microcontroller outputs. It allows, among other things, to control servo motors, adjust motor speed or change the brightness of LEDs. Interacts via I2C, operates at 3.3 V and 5 V.

Main features:

• Logic voltage: 3.3 V to 5 V
• Servo motor supply voltage: up to 6 V
• All outputs are shown on the board
• Integrated clock resonator, which eliminates the need for the microcontroller signal to be constantly sent to the system
• Ability to select I2C bus address (0x60-0x80) via jumpers, allowing connection of 62 devices
• The PWM signal resolution is 12 bits, the frequency can be adjusted between 40 Hz and 1000 Hz
• It has push-pull or open-drain digital outputs
• Equipped with protection against reverse connection of power supply voltage
• The board has holes for soldering a large capacitor in case interference occurs due to excessive servo motor current
• The output circuits have 220 Ω resistors connected in series, allowing you to directly control the LEDs
• The kit includes connectors for self-assembly:
• 1x screw - connect power supply
• 4x 3x4 gold pin strips, 2.54 mm, for servo connection
• 1x 1x6 gold pins for wiring logic signals
• The module dimensions are 62.5 x 25.4 x 3 mm
• No joints: 5.5 g
