This low-cost Pi uses the same processor as the model 3 B+, but does away with the Ethernet jack and three of the USB ports. It's still compatible with all Pi operating systems and software, and has the exact...

This tiny  DC Motor in Micro Servo Body is an interesting motor - it's the same size and shape as our micro servo but it isn't a servo. It's more like a DC motor + plastic gear-train in a box. It's not a super powerful motor, it would do well as a little robot wheel. It's also a lot less expensive than a micro servo (continuous or non-continuous) because there is no control board inside. Controlling speed is done by...

Need to make a tiny robot? This little micro servo rotates 360 degrees fully forward or backwards, instead of moving to a single position. You can use any servo code, hardware or library to control these servos. Good for making simple moving robots. Comes with five horns and attachment screws, as shown. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in...

CircuitPython is our beginner-oriented flavor of MicroPython - and as the name hints at, its a small but...

Push once to turn on, push again to turn off! This clicky switch makes a great power switch or mode toggler. We like this switch because it's breadboard friendly and more fun than a power switch. Can reliably handle up to 500mA and up to 50V. This is a really satisfying switch. The leads are not on a perfect 0.1" grid so for use with a breadboard just bend the leads out just a tad and snap into a solderless breadboard or perfboard.

This USB cable adds a DB9 serial port to your computer or laptop. Works with MacOS X, Linux and Windows. Note that this provides (approximately) +-6V serial (RS232) not 5V serial (TTL), good for old devices like GPS, handhelds, programmers, etc with chunky DB9's on the side. Some cheaper RS232 cables 'cheat' and only give you 0-5V which wont work with some devices - this one has a true voltage doubler/inverter to make it more...

Upgrade a project that uses a photocell with the GA1A12S202 analog light sensor. Like a CdS photo-cell, the sensor does not require a microcontroller, the analog voltage output increases with the amount of light shining on the sensor face. This sensor has a lot of improvements that make it better for nearly any project. The biggest improvement over plain photocells is a true log-lin relationship with light levels. Most light sensors have a...

This T-Slot Photo Interrupter with Cable is a simple plastic sensor with two elements - an IR LED and an IR photo-transistor, situated across a U-shaped gap. You can control the IR LED and turn it on to transmit IR light across the gap, to the detector on the other side. This makes it perfect for detecting when something is in the slot. When there's something blocking the light, the sensor turns off, when the object goes away, the sensor...

This pressure sensor from Freescale is a great low-cost sensing solution for measuring barometric pressure. At 1.5 hPa resolution, it's not as precise as our favorite pressure sensor, the BMx280 series, which has up to 0.03 hPa resolution so we don't suggest it as a precision altimeter. However, it's great for basic barometric pressure sensing. The sensor is soldered onto a PCB with 10K pull-up resistors on the I2C pins. This chip is...

These are very unusual motors, but we thought they could be handy for projects that need a small geared-down motor. At the core is a 'pager motor' - a small thin DC motor that runs on about 3VDC. That motor is then geared down inside the red-plastic body of the motor. Finally, the output axle is connected to a plastic triangle that has a bent-wire return spring. There are two plastic stops built into the outside of the motor. If you keep...

Inductive charging is a way of powering a device without a direct wire connection. Most people have seen inductive charging in a rechargeable electric toothbrush: you may have noticed that you recharge it by placing it into the holder, but there's no direct plug. These chargers work by taking a power transformer and splitting it in half, an AC waveform is generated into one, and couples into the second coil. This is a basic charger set, and...

Adding to our collection of somewhat specialized motors, this Rotating Door Lock Motor is a DC Gearbox motor with a little pocket that is intended for a door lock mechanism. The motor only turns 90 degrees clockwise or counter-clockwise and will stall (but not strip) if you try to keep running it past the angle. It's geared down so it has high torque, but that also makes it slow - it is about 5 seconds for it to rotate 'closed' or...

Harder, better, faster, stronger!  All the control and customization for your robot project. The Parallax Feedback 360° High Speed Servo has the functionality of a light-duty servo, continuous rotation servo, high-speed servo, and encoder in one convenient package - what a triple threat! Like most continuous rotation servos, this is controlled by a standard 50 Hz pulse-width-modulation signal. But it adds a little extra - a...

When you need to switch a lot of power, N channel MOSFETs are best for the job. These FETs can switch over 60A and 30V and are TO-220 package so they fit nicely into any breadboard or perfboard. Heat sinking is easy with TO-220's, but because of the very low Rds(on) of down to 0.009 ohms (depending on the Vgs - check the datasheet) you can get away with no heatsinking for pretty high loads! The threshhold voltage is also very low, less than 2.5V...

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over I2C with 1% precision. Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the...

Power over Ethernet (PoE) splitters can make your project wiring a breeze - and best of all they work to connect any 802.3af-capable router to any Ethernet device, even if it doesn't natively support PoE! The splitter takes a unified PoE signal (data and power) from one RJ-45 cable, and then separates the data (Ethernet) and power (5 VDC regulated) into two different lines for non-PoE devices. This is an economical, practical,...

This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high. You can also solder a wire to the middle pad and create your own capacitive pad if the...
