PCB Bookmark 2nd Generation (USB-HUB + Card Reader)

 
Overview
This is a PCB bookmark/USB-HUB + card reader based on SL2.1A and GL823K-HCY04.
The USB-HUB only has two ports mainly for aesthetic reasons; the punched holes in the USB-A female connector are a bit obtrusive, since most people use it as a bookmark. It could be expanded to have four ports.

USB triaxial magnetic field sensor electronic compass
The 0.91-inch OLED screen displays the direction and angle of the three-axis magnetic field in real time. It can be used simply by plugging in a 5V USB power supply. A download port is reserved for easy modification and download of the microcontroller program later.
LCSC EDA Professional Edition design schematic and PCB layout;
USB powered, it displays the three-axis magnetic field direction angle on a 0.91" OLED screen upon plugging in;
supports serial communication, with 9600, N, 8, 1 communication data transmitted as plaintext strings for easy reading and processing by the host computer
; the host computer for displaying the three-axis magnetic field direction data developed using LabVIEW programming;
the data format displayed by the serial port assistant;
a reserved download port for subsequent modification and download of the microcontroller program, using STC8G1K08A as the microcontroller master and CH340N as the USB communication chip.
