Love Tomb Style No. 263-GL827 Card Reader

Overview

LoveTomb263-GL827

Input voltage: USB 5V of course

Function:

Provides read and write functions when only one side of SD/TF is inserted. The speed is based on USB2.0 and will not exceed 30M speed.

Regarding write protection: The RWP resistor will trigger write protection regardless of whether it is welded or not. The WP pin of the chip needs to be grounded. Before I updated to the V2 PCB, the V1 version of the PCB could only enable writing by connecting the WP flying wire to the ground.

The picture below shows the read test. The target hard disk is 4-stick 15131+2246EN that I soldered by myself. It can reach U2 full speed.

The speed of USB2.0 is indeed not high, but the peripherals of this solution are very simple. You can integrate it into your MP3 and other solutions.
