Welcome to our shop! Description: The CP2104 is a highly integrated module that includes a built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART). It supports modem full-featured signals and does not require any external USB devices. The CP2104 functions similarly to other USB-UART switching circuits, virtualizing the PC's USB port into a serial port through the driver for expansion purposes. Features: - Built-in USB transceiver, no external circuit breaker required - Built-in clock circuit, no external circuit breaker required - Built-in power-on reset circuit - The voltage regulation inside the product can output 3.3V voltage - Meet the requirements of the USB2.0 specification - The SUSPEND pin supports USB status suspension - The asynchronous serial data bus is compatible with all handshake and modulation regulator interface signals - The supported data formats are data bit 8, stop bits 1, 2, and check bits - Built-in 512-byte receive buffer and 512-byte transmit buffer - Support hardware or X-ON/X-OFF handshake - With self-recovering fuse to protect against unexpected short circuits - With an indicator light for clear working status - Supports both power supply outputs of 3.3V and 5V Specification: - PCB board size: 30.5mm*17mm - PCB board color: Blue - Chip: CP2104 - Support OS: Windows 98/2000/XP/7/8/10, MAC OS-9, X-Windows CE, Linux 2.40 or higher version Package list: - 1 * Module - 1 * Wire Note: The actual product color may deviate from the photo due to light.
