It looks so easy and yet I still learned so much during its creation. What did I use for it? - ESP8266 WiFi module - Special Christmas LED lighting with WS2811 drivers - Raspberry B v3 - Raspberry camera (for everyone to see that the tree is really lighting up) Greetings from Matúš Čopík, author https://www.soselectronic.com/articles/no-name/technical-background-of-iot-tree-competition-2119
What about production technology of PCB, is it more valuable production either by etching or by milling? How to design and produce prototype?
Aká je technológia výroby DPS? Je výhodnejšia výroba DPS leptaním alebo frézovaním.
At a PCB design it´s also necessary to consider possibilities of electrical testing. In such cases it is necessary to create some space where we can connect the sensor and measure the necessary parameters (voltage, current, etc.). This means that we need to test electrical functionality of the PCB.
