Product Description:
CH341A USB serial adapter module for USB-to-SPI, I2C/IIC, UART TTL, ISP, EPP, and MEM communication applications. It connects through a standard USB-A male interface and can add a serial port or support simple digital I/O control through USB.
Core Selling Points:
Supports multiple serial communication modes including UART, I2C, SPI, and synchronous 2-wire or 4-wire interfaces. Features hardware full-duplex serial communication with a built-in transceiver buffer and baud-rate support from 50bps to 2Mbps. Provides working-status indication and dual interface output. Supports serial data formats from 5 to 8 data bits, with odd, even, blank-sign, or no parity options.
Technical Specifications:
Model: CH341A. USB interface: full-speed USB device interface, compatible with USB 2.0; standard USB-A male design. Power: direct USB connection to PC; output voltage selectable as 3.3V, 5V, or no output. Interfaces: SPI, I2C/IIC, UART TTL, ISP, EPP, MEM, RS232, and RS485. Parallel port modes: EPP and MEM. I2C supports 4 transmission speeds. Serial baud rate: 50bps to 2Mbps. Operating system support: Windows 98, ME, 2000, XP, Server 2003, Vista, Server 2008, and Windows 7, including 32-bit and 64-bit systems.
Before Purchase:
RS232, RS485, and other interface support requires a level conversion module, which is sold separately. Confirm that your target system uses 3.3V TTL or 5V TTL levels and that the required interface and voltage-output setting match your application.
