The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC. It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment...

This rugged wheel is designed to fit securely on the output shafts of our micro and 15.5D metal gearmotors. These gearmotors should be mounted onto the side of the hub with the protruding teeth, as shown on the right. The output shaft...

These plastic mounting brackets allow you to easily and securely mount the ubiquitous 10 mm × 12 mm × 26 mm metal gearhead motors first popularized by Sanyo’s 12GN series (e.g. NA1S…NA3S), such as our micro metal gearmotors. We also...

Overview This ball caster kit includes a black ABS housing, a 1/2" diameter metal ball, two spacers (1/16" and 1/8" thick), and two #2 screw sets. The total height of the ball caster, 0.53", can be increased to about 0.7" using the...

Getting started with the Maestro Servo Controller Overview Maestro family of USB servo controllers: Mini 24, Mini 18, Mini 12, and Micro 6 The Mini Maestros are highly versatile (and compact) servo controllers and general-purpose I/O...

This disc load cell (sometimes called a strain gauge) can translate up to a whopping 200kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and...

Although it is a common measurement, accurately reading pH is very difficult. Atlas Scientific’s EZO-pH circuit gives engineers the ability to read pH with the same accuracy and capabilities that were traditionally only found in...

This Atlas Scientific Lab Grade pH probe is our highest accuracy pH probe. The internal double junction lets you read the pH of protein rich solutions without damaging the probe. The green EXR glass tip makes pH sensing in highly pure...

This little 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...

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller. To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen...

The Flow deck gives the Crazyflie 2.X the ability to detect its motions in any direction. The VL53L1x ToF sensor measures the distance to the ground with high precision and the PMW3901 optical flow sensor measures movements of the...

Add quadrature encoders to your micro metal gearmotors ( extended back shaft version required) with this kit that uses a magnetic disc and hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate...
