PCB of the day! Adafruit I2C Stemma QT Rotary Encoder Breakout with NeoPixel - STEMMA QT / Qwiic 🔧🔄🎛️

Rotary encoders are soooo much fun! Twist them 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 they're a real challenge to use: timers, interrupts, debouncing…

This Stemma QT breakout makes all that frustration disappear - 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 over I2C. Plug it in with a Stemma QT cable for instant rotary goodness with any microcontroller from an Arduino UNO up to a Raspberry Pi.

You can use our Arduino library to control and read data with any compatible microcontroller. We also have CircuitPython/Python code for use with computers or single-board Linux boards.

PCB of the day! HUSB238 USB PD Sink Breakout 🔌🔋💡

USB C has a nifty power management system where, by default, you can get a classic 5V at 1A power out from a power supply or port, but with some fancy twiddling, you can request higher voltages and currents. We've always wanted a simple breakout that could get you a range of voltages using just jumper pads, but we only had a little luck with IP2721. Then we found this chip - the HUSB238 https://en.hynetek.com/pdsink.html - used in a USB-to-DC cable, which seems perfect! It can do 5V to 20V with just a resistor setting and set the current. There's also an I2C interface that can be used to set them if the settings are persistent - we'll have to try it out. There's a library here if you want to see what the registers are like https://github.com/ltyridium/HUSB238-lib. Here's our draft for a breakout design.

PCB of the Day! Adafruit AMG8833 IR Thermal Camera Breakout - STEMMA QT 🔥📸🔌

Add heat-vision to your project with an Adafruit AMG8833 Grid-EYE Breakout! This sensor from Panasonic is an 8x8 array of IR thermal sensors. When connected to your microcontroller (or raspberry Pi) it will return an array of 64 individual infrared temperature readings over I2C. It's like those fancy thermal cameras, but compact and simple enough for easy integration.

PCB of the day! Add oodles of analog inputs with an 8-channel ADC 🔌📊🔧

Many microcontrollers have ADCs these days for reading analog/resistive sensors like potentiometers, thermistors, LDR light sensors, etc., but sometimes you need MOAR! or maybe you're using a single board computer like a Raspberry Pi that has no ADCs at all…the ADS7830 is an affordable 8-channel ADC with I2C interface, so it's easy to include with any platform. There are 2 address pins, so you could have 4 x 8 = 32 total ADC channels with chain-able Stemma QT cables. You can get up to 70 Ksamples per second, but only 8-bits of resolution, so it's suitable for rough sensor measurements. This would be a great way to add a ton of potentiometers to a build, especially if it contained a Raspberry Pi, prototype coming soon!
