Antennas are sensitive to their surroundings. Thus, when there’s an antenna on the PCB, the layout for the design should take the requirements of the antenna into account, as this can make a huge ...

The hardware was assembled by connecting the Arduino UNO R4 WiFi, the PZEM 004T, the current transformer, and the OLED ...

Creating PCBs at home is quite easy these days (vias not withstanding), but even the best DIY methods usually can’t match the resolution offered by commercial PCB production lines. Large traces are ...

Semiconductor devices can modify their behaviors based on the parameters written to the internal registers, or the control-voltage levels provided to the input pins. Pin count is sometimes a limiting ...
