USB triaxial magnetic field sensor electronic compass

Overview

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.
