AJMRTC ADT-UD5 USB Test PCB Breakout Board, USB 2.0 Male & Female Socket Connector Module, 480Mbps USB Signal Test Adapter Compatible with Raspberry Pi, Rock Pi 4, ESP32, STM32 and Other MCU Developme

AJMRTC ADT-UD5 USB test breakout board is a practical inline debugging fixture for USB 2.0 circuits. It integrates USB-A male and USB-A female connectors on one compact PCB, which can be inserted directly into an existing USB connection without cutting or soldering cables. It complies with USB 2.0 specification and reaches a maximum transfer speed of 480Mbps. The reserved breakout pins bring out the power, ground and differential data lines, so engineers can conveniently test supply voltage, continuity, waveform quality and communication status. The gold-plated contact design ensures stable connection after frequent plug-in and plug-out cycles. It works well with single-board computers including Raspberry Pi and Rock Pi 4, as well as common microcontroller platforms such as ESP32 and STM32. It is widely used in electronic labs, product prototype testing, USB peripheral troubleshooting, student electronic experiments and DIY embedded development projects.
