The OM11055 is a PCF8883 evaluation board which can be used to demonstrate and evaluate the PCF8883 capacitive proximity switch. The PCB is designed to make it easy to adjust the switch’s sensitivity. The board can be powered using a Mini USB cable or a 9V battery.
The PCF8883 Evaluation Kit OM11055 is a development board for the single‑channel PCF8883 capacitive proximity switch. It can be powered via a mini‑USB cable or a 9 V battery and includes four built‑in sensor plates plus connectors for external sensors.
The manual explains how to select operation modes with jumper J9, configure sensor plates, adjust sensitivity by swapping through‑hole components, and use the optional high‑impedance op‑amp for voltage monitoring.
| Power supply options | Mini USB cable or 9 V battery |
|---|---|
| Number of sensor plates | Four built‑in sensor plates |
| Operation modes (jumper J9) | Pulse, toggle, momentary switch |
| High‑impedance rail‑to‑rail op‑amp (U2) | Optional voltage buffer for CPC pin |
Connect the supplied mini‑USB cable to a PC, USB power adapter, or attach a 9 V battery to the board.
Place a jumper on J9: no jumper for pulse mode, jumper across TOG‑TIM for toggle mode, or jumper across SW‑TIM for momentary (push‑button) mode.
