JeeLabs Dimmer Plug


Quantity discounts available
SKU: JL057X Category:


The Dimmer Plug is a small board containing the PCA9635 16-channel PWM LED
driver. This driver communicates directly over I2C. There is a “DimmerPlug” class in the Ports library to interface with this driver, to set up to 16 individual light levels and blinking. Discrete transistors or MOSFEts, as well as Darlington arrays can be added to drive more LEDs or incandescent lamps in series or in parallel. An I2C bus running at 3.3V is used as interconnect, with all the power and signal lines brought out to to both sides of the board to allow daisy-chaining with other I2C-conformant boards.
The SMD Parts Assembled version comes with the SMD-sized PCA9635 chip and decoupling capacitor already soldered onto the board. This plug has 16 outputs, available via three 6-pin headers. The Modern Device version of this plug ships with three six pin female headers. 6-pin male headers for this and all other JeeLabs plugs can be found here (straight) and here (right angle). Three solder jumpers support up to 8 boards on a single I2C bus, for a total of 128 individually-controllable outputs. Please note that the headers do not come soldered to the board. If you would like them to be make sure to include 5 units of Super Service with your order.
The PCB Only version contains just the printed circuit board for the Dimmer Plug. No parts, no headers.
The documentation and full design details are freely available.
