Perfect device for small projects. Initially I was looking for a ESP32 with TFT screen when I found this on PI-Huts website. I was making a flow indicator for use in verifying/setting analyser sample flows in Industrial sites. The EdgeBadge has more than I needed to achieve this without having to make a custom shield to host the connections on, so no soldering iron needed here. When looking at the spec's I noticed that it also had some designs for a 3D printed case, again perfect as no need to design a custom case. After quickly getting the EdgeBadge programmed with Circuitpython, in less than 200 lines of code I had exactly what I needed. A device that had audio and visual notification of when the target setpoint was reached. The 5 neopixels on the front are used for a quick indicator of how near the setpoint is without having to focus in on the display if the regulating valve is at a distance from the measurement point, a bonus that I did not envisage in my initial concept. This was programmed while the case was printing on my 3D printer. In than a day I had a working unit that was ready to trial onsite. When using for setting flows, I now save 30 minutes per system giving time for other tasks or an early finish. Now I am making one for the other service engineer who works with me.
