Module Connections
1×3 Header
- OUT = Output is normally HIGH. The output goes LOW when switch is depressed
- VCC = Power. Typically kept at 3.3 or 5V to match the MCU it is used with
- GND = Ground which should be common with the MCU.
The module has one M3 hole for mounting.
OUR EVALUATION RESULTS:
Build quality is good on these modules.
The single mounting hole may allow the module to rotate when impacted, so mounting should take this into consideration and ensure a rotation stop is provided if necessary for the application
