About C37
C37 – Reliable UART Interface for Engineers
The C37 USB to UART Converter is an essential tool for developers and service technicians working with low-level electronics. It bridges the gap between a PC's USB port and the UART interfaces (TTL level) found on microcontrollers, sensors, and development boards. The use of the industry-standard FTDI chipset guarantees that the virtual COM port behaves identically to a physical hardware port, ensuring compatibility with sensitive programming software.
Unlike fragile "cable-style" adapters, the C37 is housed in a robust, compact enclosure suitable for DIN-rail mounting or portable use. It provides a 3.3V logic level output, protecting your 3.3V devices from damage caused by 5V signals. The device also exposes a 3.3V VCC output, allowing you to power low-power target devices directly from the USB port.
Convenient screw terminals allow for quick and secure wire connections without soldering, making it perfect for rapid prototyping and field diagnostics.
Technical Specifications:- Chipset: FTDI (Future Technology Devices International).
- Signal Levels: 3.3V (TTL).
- Connections: USB Micro-B (PC side) / Screw Terminals (Device side).
- Diagnostics: Tx, Rx, and Power LEDs.
Choose the C37 for a frustration-free debugging experience. Drivers and pinout details are available in the technical documentation.
