PCAL6534EV-ARD

PCAL6534EV-ARD is a 34-bit GPIO Arduino® shield that allows easy integration with Arduino EVKs to evaluate 34-bit general-purpose I/O expander features for interfacing with sensors, push buttons, keypads, and more. A graphical interface allows the user to easily explore the different functions of the GPIO expander to create an evaluation system. The PCAL6534EV-ARD evaluation board is a daughter card equipped with an Arduino port, designated for easy test and design of PCAL6534 IC, 34-bit port expander, controlled through FM+ I2C 2-wire bus, with RESET. The board is fully compliant with IMXRT1050 EVK, LPCXpresso55S69 (LPC55S69-EVK) and i.MX 8M Mini LPDDR4 EVK (8MMINILPD4-EVK, 8MMINID4-EVK), including GUI software control. The board can be attached to any device equipped with an Arduino port.
