Easy e-paper finally comes to Raspberry Pi, with this bonnet that’s designed to make it a breeze to add a 2.13″ 250×122 crisp monochromic 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!
The Adafruit 2.13″ Monochrome E-Ink Bonnet for Raspberry Pi snaps onto any modern Raspberry Pi and provides a Python-programmable display with two buttons that can be used to select programs or scroll through options.
Handy for making wire harnesses or jumpering between headers on PCBs. These premium jumper wires are 12″ (300mm) long and come in a ‘strip’ of 10 (1 piece each of ten rainbow colors). They have 0.1″ male header contacts on one end and 0.1″ female header contacts on the other. They fit cleanly next to each other on standard-pitch 0.1″ (2.54mm) header. The best part is they come in a ribbon cable. You can pull the ribbon wires off to make individual jumpers, or keep them together to make neatly organized wire harnesses.
These reverse mount NeoPixel LEDs are an easy way to add a lot of small (but bright!) colorful LEDs to your project when you want the top of the PCB to be flat, or to keep manufacturing simplified by having only one side of components. They are just 3.1mm x 2.7mm x 1.7mm and can be soldered reverse mount-style using the top pads and a cutout in the PCB. Thanks to the long pads, they’re not too bad to hand solder!
The driver chip is inside the LED and has ~12mA constant current drive, so the color will be very consistent even if the voltage varies, and no external choke resistors are required making your design minimal. Power each one with 5VDC, and you’re ready to rock.
Keep wet things wet and dry things dry by detecting when the dry things get wet by accident! This palm-sized cherry-red water sensor is simple and easy to implement in your wet-dry-sensing project.
Usage is very simple: connect the minus (-) pin to ground, connect the plus (+) pin to 3 to 5V DC and then the output signal pin (S) goes to your microcontroller.
Rotary encoders are soooo much fun! Twist em this way, then twist them that way. Unlike potentiometers, they go all the way around, and often have little detents for tactile feedback. But, if you’ve ever tried to add encoders to your project you know that they’re a real challenge to use: timers, interrupts, debouncing…
This Stemma QT breakout makes all that frustration go away – solder in any ‘standard’ PEC11-pinout rotary encoder with or without a push-switch. The onboard microcontroller is programmed with our seesaw firmware and will track all pulses and pins for you and then save the incremental value for querying at any time over I2C. Plug it in with a Stemma QT cable for instant rotary goodness, with any kind of microcontroller from an Arduino UNO up to a Raspberry Pi.
