PicoBuck LED Driver
SPARKFUN¥5,298税込¥5,8281個33日以内出荷Description。The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board, allowing it to be used up to the full 36V rating of the AL8805 part.。Three signal inputs are provided for dimming control. You can use the PWM signal from an Arduino or your favorite microcontroller to dim each channel individually, or you can tie them all to the same PWM for simultaneous dimming. Dimming can be done by an analog voltage(20%-100% of max current by varying voltage from .5V-2.5V)or by PWM(so long as PWM minimum voltage is less than .4V and maximum voltage is more than 2.4V)for a full 0-100% range. A small jumper is provided for each channel to allow you to increase the drive strength from 330mA to 660mA. Two mounting holes for 4-40 or M3 screws are provided on either side of the board. They are perforated so they can be easily snapped off with a pair of pliers, if a smaller footprint is desired.。Note:。If you're going to use screw terminals, this board uses two different sizes. Check the related products for both sizes you'll need.。Note:。The PicoBuck LED Driver was made in collaboration with Ethan Zonca. A portion of each sale is given back to him.アズワン品番67-0420-83
SparkFun Capacitive Touch Slider - CAP1203 Qwiic
SPARKFUN¥2,498税込¥2,7481個33日以内出荷。Description。Do you want to replace a slider or a button on your art project or science experiment with a more interesting interface? This Capacitive Touch Slider is a "Qwiic" and easy way to add capacitive touch to your next project. With the board's built in touch pads, you can immediately start playing with the touch capabilities as three unique touch inputs or as a slider. You can also enable a touch input to act as a power button, customize the sensitivity for your own touch pads, and play with the interrupt alert LED. Utilizing our Qwiic system, no soldering is required to connect it to the rest of your system. However, we have broken out 0.1"-spaced pins in case you prefer to use a breadboard or create your own touch pads.。On the front of the board, there is an arrow shape which contains three separate capacitive touch pads. We also broke out the capacitive touch sensor lines as plated through-holes on the top of the board. You can use these pins to connect to your own capacitive touch pads. The CS1 pin connects to the left pad, the CS2 pin connects to the middle pad, and the CS3 pin connects to the right pad.。NOTE:The I2C address of the CAP1203 is 0x28 and is hardware defined. A multiplexer/Mux is required to communicate to multiple CAP1203 sensors on a single bus. If you need to use more than one CAP1203 sensor consider using the Qwiic Mux Breakout.。The SparkFun Qwiic connect system is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.。Get Started with the SparkFun Capacitive Touch Slider Guide。Features。Capacitive Touch。3 unique capacitive touch inputs。Features。Emulated slider。Power button setting。Programmable sensitivity。Automatic recalibration。I2C Address:0x28。Qwiic Enabled。Operating Range。Supply Voltage:3.3V - 5Vアズワン品番67-0427-06
