Note: The 1032_0B is identical to the 1032_0, except that you have the option of whether you want to include the USB and LED cables.
The PhidgetLED 64 allows you to independently control 64 Light Emitting Diodes. Each LED can have the current limit set individually, and the brightness controlled from 0 to 100% within that limit using current control. These LED outputs can also be used to interface other devices that benefit from current control (such as buzzers, fans, and other small, simple electronics).
Most standard LEDs have forward voltages below 2.75 Volts, and can be used with the PhidgetLED by simply soldering them to a connector-wire and inserting the wire into any PhidgetLED board output. The forward voltage will default to 2.75V, and the maximum current defaults to 20mA.

Welcome to the 1032 user guide! In order to get started, make sure you have the following hardware on hand:
Next, you will need to connect the pieces:
Now that you have everything together, let's start using the 1032!
In order to demonstrate the functionality of the 1032, the Phidget Control Panel running on a Windows machine will be used.
The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first take a look at the getting started guide for your operating system:
Linux users can follow the getting started with Linux guide and continue reading here for more information about the 1032.
After plugging the 1032 into your computer and opening the Phidget Control Panel, you will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Double-click on a Digital Output object, labelled LED Driver, in order to run the example:
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:
The 1032 uses four controller chips that allow you to vary the current and voltage supplied to each channel. It uses pulse-width modulation to vary the brightness of each LED.
You can have multiple LEDs hooked up to a single channel on the 1032, (for example, a short string of LEDs) to reduce the amount of wiring, although keep in mind that you'll lose control of the individual lights, and can only toggle or dim the entire string. When using multiple LEDs on a single channel, you'll need to increase the voltage limit for that channel. If the LEDs are too dim at the maximum voltage, you should spread them out to other channels.
If you're using high-current LEDs, you should spread your load evenly across the board to avoid having one of the controller chips overheat. There are four controller chips, each controlling the channels on a quarter of the board.

The connector used on the 1032 LED board is a Molex 70543-0003. The mating connector used on our LED cables is the Molex 50-57-9404.
Projects that require a high supply voltage, or have a lot of heat being produced from over voltage settings, will have temperature problems. This can be mitigated somewhat by understanding how channels are grouped and how the heat is distributed around the controller. On the 1032 channels are split into four groups: (0-7,24-31), (8-23), (32-39, 56-63) and (40-55); each controlled by their own individual IC. Evenly distributing the LEDs that may produce a lot of heat across these groups will balance the load on the ICs and reduce the risk of thermal overload. When thermal overload occurs, the integrated circuit (IC) controlling the involved LEDs will disable the output of all the channels it controls. For example, if thermal overload occurs due to channel 12, all of the channels 8 through 23 will be disabled by the IC until the temperature back within the operating range. Thermal protection is activated when the die of the IC reaches approximately 160 degrees Celsius. Once the thermal overload has been corrected (i.e. the IC has cooled down), the output channels will be re-enabled with the same settings as before the thermal shutdown. An error message will be produced during thermal overload.
For more information, take a look at the LED Primer.
The PhidgetLED-64 Advanced can handle any LED with a forward voltage of 5V or less, and a forward current of 80mA or less. Here's a list of LEDs we have available:

The PhidgetLED-64 Advanced comes with sixteen LED cables, enough to use all 64 LED outputs if you cut each cable in half and solder the loose ends to the LEDs. Solder the red wire to the positive end of the LED (usually the longer one) and the black wire to the negative end. If you need extra LED cables, you can find them below:

|CBL4213_0||$2.00||600 mm||26 AWG|
Use a USB cable to connect this Phidget to your computer. We have a number of different lengths available, although the maximum length of a USB cable is 5 meters due to limitations in the timing protocol. For longer distances, we recommend that you use a Single Board Computer to control the Phidget remotely.
