Description
KAmodPCF8883T is a module with a capacitive touch sensor PCF8883 from NXP. The board is equipped with a Pmod GPIO standard connector with one digital output informing about the status of the sensor output depending on the selected operating mode. Due to its small dimensions, the product can be used in many development projects.

Choice of operating mode
The KAmodPCF8883T module is equipped with jumpers enabling configuration of the chip operation mode. One of three jumpers may be on. Allows you to select the system operation in the mode:
- PB (Push Button) - the output is high as long as the probe event occurs
- PUL (Pulse) - the event is active for 1 second after the event occurs on the probe
- TOG (Toggle) - the occurrence of an event on the probe causes a change in the state on the output pin
Touch probe
The KAmodPCF8883T module has a built-in 10 x 6 mm touch probe.
LED indicator
The KAmodPCF8883T module is equipped with a diode indicating the output pin status of the chip. It allows easy status reading and quick module diagnostics without the need to connect external circuits to the output pin.
