Ebyte E30T-433T20S(150°C) 20dBm High temperature resistance UART 433MHz Wireless serial port transparent transmission module
E30T-433T20S(150℃) Half-duplex 150℃ high temperature resistant wireless serial port module suitable for high temperature working scenes. [Operating frequency]：410~450MHz [Transmitting power]：20dBm [Communication distance]：3.5km [Product size]：16*26mm [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.
