It’s important to remember that software serial ports consume time and resources. An emulated serial port must do everything that a hardware port does, using the same processor your sketch is trying to do “real work” with. Whenever a new character arrives, the processor must interrupt whate...
Link time optimization (LTO for short) optimizes the code at link time, usually making the code significantly smaller without affecting performance. You don't need to hit "Burn Bootloader" in order to enable or disable LTO. Simply choose your preferred option in the "Tools" menu, and your ...

We will update our backers at least once a week, and will publish any good news when it happens. As it is our standard, we always keep our products up-to-date—every time we think that an upgrade is needed, we will release it. Each module will be automatically updated by the cloud ...
We are committed to meet you, IoT developers, where you are, and a significant number of you happen to use the Arduino IDE. We're making the experience better than ever by releasing a first-class int...
