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.
