How to use

Plug the USB 2.0 A connector into a computer USB port to provide power and a TTL serial interface. Connect the individual jumper sockets to the target device’s TTL pins (for example TX, RX, GND and VCC as required). Ensure correct pin mapping and voltage levels before powering the target device. Use appropriate terminal software or a programming tool on the PC to communicate with the connected device.

Usage recommendations

Verify the target device’s required logic voltage (e.g., 3.3 V or 5 V) and pin assignments before connecting. Avoid shorting pins while the USB port is powered and disconnect the cable when making wiring changes. Use static-safe practices when handling sensitive microcontrollers or modules.
