Copper vs MQTT Manager

Open any EAGLE CAD file (from version 6 and above) directly on your iPhone and investigate the PCB layout and schematics with your finger. Select parts and signals, manage parts and Bill of Materials. Copper creates 3D versions of your PCB including parts that you assign from our extensive 3D model library to your footprints. Copper then renders a photorealistic representation in real time that you can touch, rotate and move in a virtual studio. Setup lights and materials like the solder mask or the floor. Import EAGLE files from any source like the web (just download a ZIP file with EAGLE files), from Github, your Dropbox, or send PCB files directly via Airdrop, Mail or iMessage to your iPhone or iPad. Every file you import is kept in Coppers library. This way you can build up a nice library of PCBs and Schematics right in your pocket. Copper is also available for the Mac and both share the same codebase and file format.

MQTT Manager is a general-purpose application to read and write topics on a MQTT broker through a friendly interface based on widgets. The application is organized in 4 tabs and each tab can contain any number of widgets. Widgets are chosen between the available ones: * Display: Shows a numeric value or text (scrolling it) * Gauge: Shows a numeric value over a graded scale * LED: Shows the value of a topic as a LED on or off * Graph: Shows the values of a topic as a graph * Switch: Writes a value to the topic depending on the switch position * Secure Switch: Similar to the Switch Widget. To operate the switch, the protection has to be remove with a click on the yellow bands though * Switch & LED: Writes a value to a topic and shows its value as a LED on or off * Knob: Writes a value to a topic proportional to the position of the knob * Slider: Writes a value to a topic proportional to the position of the slider * Push Button: Writes a value to a topic when the button is pushed and another value when it is released * Text: Writes the value entered by the user to a topic The application includes: * a complete user manual * documentation to learn the MQTT basics * the documentation to install a private MQTT broker on: * Raspberry Pi * Linux * macOS * documentation to use the Adafruit IO service instead of your MQTT broker. This allows to get started in a few minutes, without installing additional software * documentation includes how to configure a local mosquitto broker with authentication, using SSL and using client certificates for users/devices identification and authentication * Arduino ESP32, Arduino MEGA, Arduino Nano 33 IoT and MKR1000 sketches to create a MQTT node which sends data to the application and can be controlled by it * Raspberry Pi Pico W micropython script to create a MQTT node which sends data to the application and can be controlled by it
