Adafruit Wide-Range Triple-axis Magnetometer - MLX90393
US$15.33
Measure the invisible magnetic fields that surround us, with this wide-range magnetometer. The MLX90393 is a wide range magnetic field sensor, that can measure 16-bits in ranges from ±5mT up to ±50mT in all 3 axes. Compared to most magenetometers, this gives a huge range, which makes it excellent for detecting magnets and magnetic orientation, rather than the Earths magnetic field. (Magnets have a much stronger field that overwhelms most magnetometers that would normally be used for orientation with respect to the North Pole).

Adafruit 2.7" Tri-Color eInk / ePaper Display with SRAM - Red Black White
US$49.95
This breakout has a 2.7" tri-color (red, black, and white) display. It has 264x176 black and red ink pixels and a white-ish background. Using our CircuitPython or Arduino libraries, you can create a 'frame buffer' with what pixels you want to have activated and then write that out to the display. Most simple breakouts leave it at that. But if you do the math, 264 x 176 pixels x 2 colors = 11.5 KBytes. Which won't fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 12KB?

US$44.10
Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it a breeze to add a tri-color eInk display. Chances are you've seen one of those new-fangled 'e-readers' like the Kindle or Nook. They have gigantic electronic paper 'static' displays - that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!

US$42.35
Alert tower lights are really easy to use. The brown wire is the common +12V power line, then the other wires are connected to ground to activate each of the three LED lights: red wire for red light, yellow wire for yellow light and, you guessed it, green wire for green light. The final orange wire is what controls the buzzer which will sound continuously when the wire is grounded. We did notice that you can't have both the yellow and red lamps on at once, and in general its best to only have one lamp lit at a time for max brightness. The buzzer can be turned on whenever, it does not seem to be affected by the lights.

At the Feather 328P's heart is an ATmega328P clocked at 8 MHz and at 3.3V logic, a chip setup we've had tons of experience with as it's the same as the Pro Mini and similar to the Adafruit Metro 328. This chip has 32K of flash and 2K of RAM, and we paired it with a SiLabs CP2104 to give it USB-to-Serial program & debug capability built in. Works great when you want to keep your classic Arduino code compatibility, but want to use one of our dozens of FeatherWings To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.

1894-ADA Flex PCB Material - Pyralux - 6" by 6" Square - AC 352500EY
US$17.24
Finally, the conductive material you've known you wanted but never knew you could have, its a sheet of flex PCB material! This is the stuff used to make flexible circuits, but raw and unetched. You can treat it just like 1 oz copper clad, etch it with ferric chloride (or other PCB etching systems) or cut with scissors. It may even be possible to laser or CNC engrave (we haven't tried it ourselves but we'd love to hear about it if you get any results.) Pyralux is the brand name of Dupont's flex PCB material that's used in cell phones and other small circuits. One side of it's 1 oz copper while the other side is polyamide for strength and flexibility. The material can be manipulated through and around small areas and won't crack as easily as copper tape. Pyralux is used in a ton of consumer-grade electronics and one of the reasons why things like your cell phones have advanced from bulky and cumbersome to miniature super computers.

This means that when activated with up to 12VDC, the solenoid moves and then the voltage is removed it springs back to the original position, which is quite handy. Many lower cost solenoids are only push type or only pull type and may not have a captive armature (it'll fall out!) or don't have a return spring. This solenoid has 4xM3 (metric) threaded holes in the bottom for easy mounting.

3595-ADA Adafruit APDS9960 Proximity, Light, RGB, and Gesture Sensor
US$11.95
Add basic gesture sensing, RGB color sensing, proximity sensing, or ambient light sensing to your project with the Adafruit APDS9960 Proximity, Light, RGB and Gesture Sensor. When connected to your microcontroller (running our library code) it can detect simple gestures (left to right, right to left, up to down, down to up are currently supported), return the amount of red, blue, green, and clear light, or return how close an object is to the front of the sensor. This device uses an I2C interface so it's easy to wire up and use. The APDS9960 from Avago Technologies has an integrated IR LED and driver, along with four directional photodiodes that sense reflected IR energy from the LED. It's proximity detection feature allows it to measure the distance an object is from the front of the sensor (up to a few centimeters) with 8 bit resolution.

3342-ADA 2x40 Right Angle Edge Connector for micro:bit
US$6.92
This is a connector that fits directly to the edge contacts of a BBC micro:bit. The connector has 80 pins, but because of the different widths of the micro:bit edge contacts, some of the micro:bit contacts will map to more than one of this connector's pins. Also, the back half of the pins are not used at all. The edge connector gives access to all the important pins on the bottom edge of the micro:bit. Check the datasheet for the pin spacing and orientation. This connector is best used with a custom PCB!

3366-ADA 36-pin Stacking header - pack of 5!
US$9.95
Stacking headers are a twist on the standard/common male and female header sets. In this case you have one header that has a socket on one end, and a long tail that gets soldered through a PCB. When soldered into a through-hole pad, the long tails can plug into another board's female headers while the sockets above the PCB allow another board to be plugged in. This means you can stack PCBs, as many as you like, on top of each other. You can even plug the lower board into a solderless breadboard, or plug wires into the top board's sockets.

3290-ADA Platinum RTD Sensor - PT100 - 3 Wire 1 meter long
US$22.67
For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0°C, thus the name PT100. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT100's have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability.
