Maya Posch writes about Aaron Christophel disassembling a €15 UGreen USB-C cable rated at 240 watts, which features an integrated IPS LCD screen and a single touch control. The teardown reveals a PCB with an EN32LF056 Cortex-M0+ MCU, voltage regulators, and a MOSFET for backlighting. By probing the exposed SWD interface, Christophel confirmed the chip has 64 kB of Flash and 4 kB of SRAM, then flashed custom firmware to display video frames on the tiny display.

- A commenter noted that such dense integrated cables raise concerns about secure pairing and encryption for USB connections
