Description。Rotary encoders can be used similarly to potentiometers. The difference being that an encoder has full rotation without limits(It just goes round and round). They output gray code so that you can tell how much and in which direction the encoder has been turned. They're great for navigating menu screens and things like that.。This encoder is especially cool because it has a common anode RGB LED built in， as well as a push-button. This version has an updated material that is heat resistant and slightly changed dimensions， but should still work well with our rotary encoder breakout board.。Features。Switch Travel：0.5mm。Shaft Diameter：6.0mm。Shaft Length：18mm。Vertical Through-Hole Mount。24 Pulses per Rotation。Red/Green/Blue LED。Pushbutton

Description。If you're looking for a fully-featured Raspberry Pi 4 case， then look no further than the Argon ONE Pi 4 Raspberry Pi Case. In addition to providing passive and active cooling to keep the Pi 4 running cool， it incorporates multiple pieces to allow for access to different levels of the board like a magnetic dedicated door for the 40 pin connector that provides pin numbers and labels. An included fan HAT provides software controllable， active cooling while the aluminum enclosure provides passive cooling through two extrusions that provide a heat sink for the ICs on board(thermal tape included). An additional interface board plugs into the Pi and redirects all the connectors(outside of the 40 pin)to the one side of the enclosure. But probably the best feature is a properly configured power button that provides the ability to safely shutdown， reboot， or force shutdown the Pi.。Features。Passive and active Cooling。All connectors positioned to one side of the enclosure。Magnetic door provides access to the 40 pin header without exposing the board。Aluminum enclosure with plastic base。Power button for safe power cycling
