GY-273 QMC5883L clone HMC5883L magnetometer for Arduino, esp8266 and esp32
The sensor GY-273 QMC5883L clone HMC5883L magnetometer for Arduino, esp8266, and esp32 is cheap and reasonably precise but needs some check for the clone version.

STM32: WiFiNINA with ESP32 WiFi Co-Processor
We have already looked at how to add a wiring connection to an STM32, but sometimes the only solution can be a Wireless or WiFi connection, and in this article we are going to see how to manage a complete WiFi solution.
i2c Arduino: how to create network, parameters and address scanner
I love the I2C protocol, and when I need a sensor, every time I try to find one with this protocol, I have also written some libraries for various sensors that use I2C.
In this first article, we are going to learn the basics, then how to create a network with our Arduino UNO and MEGA. Arduino has an interesting feature that can work as a Master and as a Slave.
Flying Bear Ghost 5 simple spacer for dual drive extruder
I have a little problem with my Flying Bear Ghost 5; the filament does friction on the filament sensor because it changes angle when extruded, so I added a simple spacer to fix this.
GY-291 ADXL345 i2c spi accelerometer with interrupt for esp32, esp8266, stm32 and Arduino
The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. This device works with i2c and SPI protocol and Is suitable with Arduino, esp8266, stm32, and esp32.
STM32: ethernet enc28j60 with plain (HTTP) and SSL (HTTPS)
We already saw the w5500 devices to make a wired connection with STM32; now, we will examine enc28j60, a cheaper device with few resources but relatively stable and widely diffused. We also try to add SSL for a secure connection.
Arduino: fast external SPI Flash memory
For devices like Arduino UNO, we can use the SPI Flash with a basic and very light library, but It can manage a good quantity of memory (from 256Kb to 64Mb), and it’s enough for a lot of projects.
