Description
Highlight
- Walk-In Price: RM94
- Warranty: 12 Months (T&C Apply)
- Configurable push-pull or open-drain output
- Output enable pin to quickly disable all the outputs
- Reverse polarity protection on the terminal block input
- Green power-good LED
DESCRIPTION
- It's an i2c-controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!
- It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)
- 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot of servos or LEDs
- Adjustable frequency PWM up to about 1.6 KHz
- 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
- Configurable push-pull or open-drain output
- Output enable pin to quickly disable all the outputs
- Terminal block for power input (or you can use the 0.1" breakouts on the side)
- Reverse polarity protection on the terminal block input
- Green power-good LED
- 3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
- "Chain-able" design
- A spot to place a big capacitor on the V+ line (in case you need it)
- 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
- Solder jumpers for the 6 address select pins
TECHNICAL DETAILS
Specifications:
Datasheets, EagleCAD PCB files, Fritzing object and more in the tutorial!
Revision History:
- Dimensions (no headers or terminal block) 2.5" x 1" x 0.1" (62.5mm x 25.4mm x 3mm)
- Weight (no headers or terminal block): 5.5grams
- Weight (with 3x4 headers & terminal block): 9grams
- This board/chip uses I2C 7-bit address between 0x40-0x7F, selectable with jumpers
- As of Feb 16, 2015 we now use a much beefier polarity-protection transistor. Functionality is otherwise the same
