Abstract
The PCA9959HN-ARD evaluation board is a daughter card equipped with
Arduino ports, designated for easy test and design of the PCA9959HN IC, 24-
channel SPI serial bus 63 mA / 5.5 V constant current LED driver. The board
is fully compliant with IMXRT1050-EVKB, 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 Arduino ports.
