This article mainly describes the use of Zero-Knowledge ESP8266 and MPU-9250 to obtain speed, gyroscope angle, and geomagnetic data.1. HardwareZero-Knowledge ESP8266nine-axis sensor: MPU-9250Dupont wi
What are the better 5V to 3.3V converters? What are the better SMD chips? I use MP2359, but I found that the SOT23-6 pin package width is too small. When making PCB, the driving load capacity may not
I have made similar circuits several times before, but in actual applications, the current limiting resistor and optocoupler were burned. I modified it myself based on the information I found on the I
