NEVB-NCA9555

NEVB-NCA9555 is a NCA9555 GPIO expander evaluation board. This is an Arduino™ compatible shield form factor PCB 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. The EVB is designed in an Arduino™ compatible shield form factor that allows easy development with Nexperia’s line of available I²C GPIO I/O expanders.
