A compact, multi-function USB tester with a 1.44" TFT LCD colour display. It monitors voltage, current, power, capacity, charging protocol, and cable resistance in real time, with support for fast-charge protocol detection and PD active triggering.
The tester integrates USB-A, Micro-USB, and Type-C interfaces, with an external 16-bit ADC and PD protocol chip for accurate measurements. It can also be used to decoy voltage from a protocol adapter to create a simple DC regulated power supply.

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- HID
- Human Interface Device is a USB device class used for keyboards, mice, gamepads and similar controls. If a board supports HID over USB, it can act like an input device to a computer without needing a custom driver.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- TFT
- A thin-film transistor display is a common type of colour LCD used for graphics screens. Knowing a product is for TFTs helps you check that the driver board matches the display’s connector, resolution, backlight, and signalling method.
