YourCee USB-TTL/RS232/RS485/CAN Serial Communication Module
Efficient data transfer is crucial when integrating systems with differing data representations. When software undergoes significant upgrades, a complete database overhaul often follows. As each software platform typically employs unique structures and data storage formats for its underlying database, seamless data conversion becomes essential.
This versatile device serves as a comprehensive solution for bridging USB devices with standard CAN bus systems. It boasts an extensive array of features, including data caching, a pass-through mode, and analog CAN capability. Supporting adjustable data transfer rates from 3 Kbps to 1 Mbps, it allows for flexible configuration within this range. To minimize signal interference, the module is equipped with 14 sets of shielding filters. Users can select from five distinct modes for frame filtering, enhancing data integrity.
For connectivity, the device integrates seamlessly via pin rows. Furthermore, it offers a broad serial baud rate range, extending from 1200 to 921600 bps, with a default setting of 9600 bps. This robust converter is engineered to facilitate reliable and efficient data exchange between USB and CAN interfaces.
Integrated USB to TTL Module Features
- Utilizes the mainstream CH340 driver.
- Compatible with various operating systems, including Windows, Linux, and more.
- Supports 3.3V/5V voltage input/output, capable of powering microcontrollers.
- Features three clear indicator lights:
- COM port connection (Yellow light) – steady.
- Data reception RX (Red light) – blinking.
- Data transmission TX (Green light) – blinking.
