This RS232 to TTL Serial Interface Module is a board with the MAX3232 transceiver integrated circuit (IC). It facilitates serial communication between TTL and RS232 ports by providing the necessary electrical signal conversion.

The RS232 Board is used for establishing RS232 communication with devices powered from 3V 5.5V. It contains SP3232 (RS-232 Transceiver) and DB9 connector used for connecting PC and MCU. The RS232 Board features ESD protection and supports hardware flow control.

RS422 interface, two-way communication. B Y Z A ultra far transmission 1000 meters. The module has ESD 15KV protection. Onboard to increase the limit of 10 ohms current limiting current protection. Module with TVS diode. Anti lightning, peak voltage. The module has 120-ohm termination resistors, which can effectively reduce the interference of long-range communication. Have the power indicator light and the data receiving and sending indicator light. Panoramic view of state data. Module TTL side using 5V DC power supply TXD RXD compatible with 5V logic signal.

RS485 to TTL Converter Module Serial Port UART Hardware Automatic Flow Control Module is based of MAX485 chip, which is one of the most relied on when working with RS485 Bus. This module supports 3.3 V and 5V power supplies, and TTL Levels. It can connect and identify up to 128 nodes on the RS485 bus. This module also supports very long range of the bus.
