Wiring Connecting Terminals - USB to 8-Way Channels TTL Serial Port Module CH348 Multi-Channel UART Expansion Board TypeC to 8 TTL HUBs PCB YR-6008

1.2 CharacteristicsBuilt in firmware, emulates standard serial ports, used to upgrade original serial peripheral devices, or add additional serial ports through USB.The serial application program under the Windows operating system on the computer is fully compatible and does not require modification.Support operating systems such as Windows, Linux, Android, macOS, etcHardware full duplex serial port, built-in independent transceiver buffer, communication Baud supports 1200bps~6Mbps.The serial port supports 8 data bits, supports odd parity, even parity, and no parity, and supports 1 or 2 stop bits.Each serial port has a built-in receive FIFO of 2048 bytes and a send FIFO of 1024 bytes.Supports half duplex and provides 4 TNOWs indicating that the serial port is sending status, which can be used to control RS485 transceiver switching.By adding a level converter device, it supports interfaces such as RS232, RS485, and RS422.Built in EEPROM, it can configure chip VID, PID, high current value, manufacturer and product information strings and other parameters.1.3 Indicator lightsRed light: Connect USB, 3 The 3V power indicator light is on.Green light: The computer driver has been successfully installed and the green light is on.Normal: Only when both indicator lights are on can it be used.
