STM32F4 Black-pill: WiFi shield (WiFiNINA)
For me, It’s very important the network connection and network limitation on STM32F4 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.

STM32F1 Blue-pill: WiFi shield (WiFiNINA)
For me, It’s very important the network connection and network limitation on STM32F1 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.
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.
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.
ESP32-CAM: control CameraWebServer from your own web page – 3
I’m going to write this simple article because I started using this device as an “external IP cam” for my web project, and I’d like to share my experiences.
ESP32 WeMos LOLIN32 EByte LoRa E32, E22 and E220 shield
I’m going to publish my LoRa shield for WeMos LOLIN32. This is one of my favorite microcontrollers, and until now, I have been using a simplified version of shield for rapid prototyping, but in the end, I created a more complete version, and I share it with everyone.
