5. GETTING STARTED
Programming via SWD
1. Connect debug probe to SWD connector (X1)
2. Set R8 to the desired value (current limit)
3. Power on the Evaluation Board (IO-Link interface L+ = 24V, L- = GND)
4. Start programming with your preferred SDK (Software Development Kit)
6. POWER SUPPLY
The Evaluation Board is supplied via the L+ voltage of the IO-Link interface which has to be 24 V. The IO-Link
interface comprises L+, L- and CQ, and it can be accessed via an M12 connector or terminal clamps. Three
SMAJ33A TVS diodes are used to provide additional protection against high voltage bursts.
At port VDD, a regulated voltage of 3.3 V is generated by a LDO regulator. This regulator supplies the digital I/O
pads of the CCE4503, the MCU and the sensors. VDD can supply additional external components, but the
overall external load at VDD must not exceed 20 mA. The current consumption of the MCU, the sensors and
external components must be below this limit.
