RTS5170 TF/SD-C Female Connector - Card Reader

Based on: rts5170_card_reader - JLCPCB EDA open source hardware platform (oshwhub.com). Inspiration for the modification
came from eMMC programmers and MMCFW card reader tutorials - Creative DIY Digital Home (mydigit.cn).
 
 
The above is a sample. The new version adds two 0603 specification 5.1k resistors, solving the problem of the CC data cable not being recognized by the computer.
 
 
(Note: the component is a 2.54mm pitch 10pF male connector!!!)
It supports use with products from my other projects.
 
The modified version adds a dual voltage switching function (VCCQ line can switch between 1.8V and 3.3V), and offers self-ejecting/non-ejecting TF card slots
. A 65K5 component is used for voltage reduction, which may have optimized the issue of VCCQ 1.8V not working (to avoid potential problems caused by using the 3.3V line for voltage reduction, it was modified to use the VBUS line for voltage reduction).
However, in my actual testing, seven or eight Samsung eMMC chips were not recognized in the 1.8V state. I added this feature simply because I saw something a member of the programmer group said, and I wrote it down on a whim.
