Newly upgraded to resolve overheating issues. Features a full - dual-circuit design (avoiding internal LDO power circuits) for lower power consumption. Built with a 4-layer PCB for industrial-grade quality; operates at very low temperatures with exceptional stability. Includes protection against burnout and reverse current.
Supports performance and speed stress testing, as well as data integrity verification.
Hardware design details: The 3.3V rail has been re-engineered to 2.7V, utilizing a fully independent - 2.7V supply for the main controller and eMMC VCC.
eMMC VCCQ is designed for a default factory voltage of 1.8V.
For eMMCs requiring higher VCCQ voltages: removing resistor R1 sets the voltage to 3.3V, while removing R2 sets it to 2.7V. Removing R2 to use 2.7V is the recommended configuration (generally, no modification is required; simply solder and use).

Note: Please contact customer service before placing an order if you require further information regarding the software.
FAQ:
1. Not suitable for data recovery purposes; updating the firmware will result in a complete format of the drive.
2. Most mobile phones do not use eMMC 153/169 chips; these are typically found in multimedia devices such as set-top boxes, televisions, laptops, tablets, and industrial PCs. You must disassemble the device to check the model number and confirm if it uses an eMMC 153/169 chip.
3. Difference between single-chip and dual-chip configurations: Single-chip setups use one chip, while dual-chip setups use two chips simultaneously. Dual-chip configurations offer double the read/write performance and combined storage capacity.
4. Firmware is interchangeable: Units flashed with the 1.81 single-channel firmware (slower read/write) can be flashed back to the 1.73 dual-channel firmware (faster read/write), and vice versa. The f
