NCA9555 GPIO expander evaluation board
NEVB – NCA9555, the NCA95xx evaluation board, 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, NCA9535, NCA9539 and NCA9595.
