Abstract
The PCA8561AHN-ARD evaluation board is a daughter card equipped with
Arduino port, designated for easy test and design of PCA8561 IC, automotive
18x4 LCD segment driver. The board is fully compliant with IMXRT1050
EVK, LPCXpresso55S69 (LPC55S69-ECK) 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.
