General Purpose Input/Output (GPIO) Expander, Evaluation Board (EVB), Arduino
The NCA95xx EVB (Evaluation Board) is an Arduino
designed for the Nexperia I²C controlled GPIO expander family. The board provides convenient
test points for GND, I²C-Bus signals SCL and SDA as well as an interrupt open drain output.
The EVB can be used for the GPIO expander derivatives NCA9555, NCA9535, NCA9539 and
NCA9595.
