Abstract
The NTS0304EUK-ARD evaluation board is a daughterboard equipped
with an Arduino port, designated for easy test and design of NTS0304E
IC, 4-bit dual supply translating transceiver, with open drain, and auto
direction sensing. 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.
