Pin Definition

The I527BV3 development board uses the X527CV2 core module. The module has 200 castellated pins, with 50 pins on each side. The table below lists the complete core-module pinout.

:::warning Voltage levels GPIO banks may operate at 1.8 V or 3.3 V. Carrier-board peripherals must use the same I/O level as the corresponding bank. High-speed, analog, power, and dedicated signals marked as unavailable for GPIO must not be treated as ordinary GPIO pins. :::
