Arduinos are great for many reasons, one of them being their ability to wire up to almost anything. But there are times when you want to connect to your Arduino without using any wires, and when you do get the desire to go wireless there are several methods to choose from. ...
Getting Started with ESP32-Bit Module and ESP32-T Development Board using Arduino core for ESP32 A First Look at ESP32 PICO Core Development Board Powered by ESP32-PICO-D4 SiP Review of an ESP32-based BLE to MQTT gateway – Part 1: GL.inet GL-S10 unboxing and teardown...
The board itself is a neat springboard for developing on – it allows you to attach a Raspberry Pi, Arduino, XBee or other Small Board Computer directly to the AP. Of course, you wouldn’t deploy a production solution like this, but you would take the solution you’re working on, and...
