[Introduction]：E30T-433T20S(150°C) is an automotive-grade, high-temperature-resistant wireless UART module designed to operate reliably in environments ranging from -40°C to +150°C. It features a half-duplex communication mode with integrated transmission and reception, supporting transparent data transmission. This surface-mount module provides TTL-level output and operates in the 425–450.5 MHz frequency band with a transmission power of 100mW. Its exceptional high-temperature resistance makes it an ideal choice for demanding high-temperature applications.
