ESP32

Overview

Based on esp32 electronic compass, the schematic diagram is divided into five parts: main control, power supply, LED, reset download and magnetometer. The shape of the PCB is octagonal, with a three-color LED on each of the eight corners. The general usage is that esp32 collects magnetometer data to determine the direction, and drives the LED through PWM, so that the LED pointing to the south is the brightest, and the brightness of adjacent LEDs decreases in sequence, thereby achieving the purpose of indicating the direction.
