USB Charger Doctor - In-line Voltage and Current Meter usb, charger, doctor, voltage, current, meter
Price: $7.50
Availability: In Stock
Item #: AF-1852 -

    The USB Charger Doctor is a handy tool that measures the working voltage and current output for any USB port and project. Plug the Doctor between a USB port and your USB device, and it will check the current draw with a 0.05 ohm resistor in line with the power pin. Data lines pass through as normal. You can use this device from 3.5-7VDC input voltage (although most USB devices tend to hover around 4.75 to 5.25) and up to 3A of current. It flips between voltage and current readouts roughly...

            Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685 adafruit, 16 channel, 12 bit, pwm, servo, driver, i2c
            Price: $14.95
            Availability: In Stock
            Item #: AF-815 -

              Want to make a hexapod walker? Maybe you're making a piece of art with tons of moving parts, or you need to drive a ton of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you find yourself running out! Not with the Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface. With this pwm and servo driver breakout, you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62...

              Analog Feedback Micro Servo - Metal Gear analog, feedback, micro, servo, metal, gear
              Price: $14.95
              Availability: In Stock
              Item #: AF-1450 -

                The Analog Feedback Micro Servo may appear to be a normal micro servo, but it is so much more. What makes this little fella special? Beyond the metal gears which keep this servo solid for the long haul in hobby systems, this servo has feedback via a potentiometer wiper on a separate wire that can be read with an analog input, such as those on an Arduino, to get the servo's position. This gives you the ability to "record" the servo's motion, or improve stability.

                Mini IR Remote Control Mini, Remote, Control, robot, geek, trossen, arduino, adafruit
                Price: $4.95
                Availability: In Stock
                Item #: AF-389 -

                  This little IR remote control would be handy for controlling a robot or other project from across the room. It has 21 buttons and a layout we thought was handy: directional buttons and number entry buttons. The remote uses the NEC encoding type and sends data codes 0 thru 26 (it skips #3, #7, #11, #15, #19 and #23) to address #0. You can use this to control something that is expecting NEC codes or you can pair this with virtually any IR remote receiver sensor. Battery included!

                    Item #: AF-2226 -

                      The NeoPixel Jewel is a lovely round PCB, home to 7 tiny WS2812 5050 (5mm x 5mm) smart RGB LEDs. Each LED has a driver chip built into it, making them individually addressable. Many units can be chained together and run by a single microcontroller by connecting the output of one Jewel into the input of another! Each NeoPixel has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and runs on 5V.
