E30T-433T20S(150℃) Half-duplex 150℃ high temperature resistant wireless serial port module suitable for high temperature working scenes.

[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.

5 M0 Input (very weak pull-up) Cooperate with M1 to determine the 4 working modes of the module (cannot be left floating, can be grounded if not used)
6 M1 Input (very weak pull-up) Cooperate with M0 to determine the 4 working modes of the module (cannot be left floating, can be grounded if not used)
7 RXD enter TTL serial port input, connected to the external TXD output pin; can be configured as an open-drain or pull-up input, see parameter settings for details.
8 TXD output TTL serial port output, connected to the external RXD input pin; can be configured as open-drain or push-pull output, see parameter settings for details.
9 TO output Used to indicate the working status of the module; the user wakes up the external MCU and outputs a low level during power-on self-test initialization; it can be configured as an open-drain output or push-pull output, see parameter settings for details. (can be left empty)
