Description
Accurate, 12-bit PWMsignal generator. Allows you to control up to 16 servos. For communication, it uses only two lines of the I2C interface. Thanks to a choice of addresses (0x60-0x80), on one bus you can connect 62 devices which gives 992 PWM channels supported by a single microcontroller.
The module as a shield for the Arduino with a set of connectors for self-soldering. It works withArduino Uno,Leonardo,Mega2560andMega ADK.
Key features
- Voltage of the logical parts: from 3.3 V to 5 V.
- Supply voltage of servos: up to 6 V.
- Built-in resonator, thanks to which the system there is no need to constantly send a signal to the microcontroller.
- Possibility to choose I2C bus address (0x60-0x80) through the jumpers which gives the possibility to attach 62 devices.
- The resolution of the PWM signal is 12 bits, the frequency is adjustable in the range of 40 Hz to 1000 Hz.
- It has digital push-pull or open-drainoutputs.
- Equipped with protection against reverse connection of the supply voltage.
- The board has holes for soldering a large capacitor when interruptions appear due to the consumption of too much current through the servos.
- It has resistors of 220 Ω that are connected in series in the circuits of outputs, through which you can directly drive LEDs.
- The kit includes connectors for self-assembly:
- 1 x screw - for attaching the supply voltage
- 4 x goldpin strips3x4, raster of 2.54 mm to connect the servos.
- 1 x goldpin strip for connecting the shield with the Arduino.
- Module dimensions: 54 x 70 x 3 mm
- Weight with connectors: 20 g
