Frequently asked questions
Does a 2-pin crystal need other components?
Usually yes. A passive crystal does not oscillate by itself, so it is normally wired to the MCU's oscillator pins with load capacitors. Use the values from the MCU datasheet.
Is a 40 MHz crystal used in ESP32 designs?
Some ESP32 designs use a 40 MHz crystal, but the requirement depends on the module or board. Confirm the frequency in the board schematic or datasheet before using this crystal.
