USB 3.0 Flash Drive DIY Motherboard NS1081 DualChannel DualLayer PCB Firmware Upgradeable 1.8V Adjustable Compatible with Dual EMMC153/169

HighSpeed USB 3.0 Performance Powered by the NS1081 dualmount dualchannel controller, compatible with two EMMC chips for combined capacity and faster read/write speeds. Industrialgrade full DCDC dualcircuit design ensures stable power delivery.; Advanced Safety & Thermal Management Features a nonstandard lowtemperature circuit design that effectively prevents overheating, burnout, and backflow issues. Supports longterm highspeed read/write without abnormal temperature spikes.; Flexible Firmware & Voltage Support Compatible with dualchannel 1.73 firmware for fullcapacity verification (runcircle data check). Includes 1.8V voltage adjustment to match different EMMC-compatible specifications.; StepbyStep Installation Required (Critical) Do not solder both EMMC-compatible chips at once.

You must first mount one side, update the firmware successfully, then mount the other side and update again (to recognise the combined capacity). Skipping this will cause failure, and a poor solder joint on one side becomes very difficult to diagnose.; PrePower Check with Multimeter After soldering, use a multimeter in continuity/diode mode: connect red probe to ground (USB connector) and black probe to measure VCCQ and VCC-compatible each should read around 0. xV. Only connect to PC for firmware update after confirming no short circuits.
