Raspberry Pi Pico, and other rp2040 boards: WiFiNINA with ESP32 WiFi Co-Processor
Even though Raspberry Pi Foundation has released the Pico W version, I still find this tutorial useful for adding WiFi to rp2040 boards using an ESP32.
We will use an esp32-wroom-32 (or esp32-s) as WiFi coprocessor and the full potential WiFiNINA library to handle it.
What do you want? A microcontrollers performance comparison
Whoever has started to peek into the wonderful world of small electronics will undoubtedly have read about Raspberry Pi or Arduino boards. This is where I personally started to ask myself, what is the right board for which project?
ESP32: ethernet enc28j60 with plain (HTTP) and SSL (HTTPS)
enc28j60 is one of the cheapest device for wired connections; in this article, we’ll learn how to manage this device for plain and SSL connection with our ESP32
ESP32: ethernet w5500 with plain (HTTP) and SSL (HTTPS)
Many people ask me for some examples of wired connections; in my mind, the first thing I thought of is the w5500 device, one of the most famous and powerful. We’ll start to learn how to manage plain and SSL requests.
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.
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.
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.
