jOY-it SBC-TTL USB-TTL Converter Module – Serial Interface for Developers
The jOY-it SBC-TTL USB-TTL converter module transforms USB signals into serial TTL levels. It is ideal for communicating with microcontrollers, single-board computers like the Raspberry Pi, or Arduino boards.
Easy connection via USB Type A – no external power supply required
Selectable voltage 3.3 V or 5 V – compatible with common logic levels
Compact module that plugs directly into the USB port – space-saving and flexible
Plug&Play on Windows, Linux, and macOS – ready to use without driver installation
What sets the SBC-TTL module apart
Unlike expensive analyzers, this module offers a cost-effective and reliable solution for serial data transmission. The conversion principle (USB to TTL-UART) is industry-standard, ensuring compatibility with a wide range of development environments and tools.
Ideal for...
Hobby electronics enthusiasts, makers, and developers who want to program or debug microcontrollers or single-board computers via a serial interface. Also suitable for educational projects and prototypes.
How to use the USB-TTL converter module
Plug the module into a free USB-A port on your computer. Select the desired operating voltage (3.3 V or 5 V) using the jumper. Connect the TX, RX, VCC, and GND pins to your target device. After driver detection, the serial port becomes available in the system.
