the Arduino/Genuino Uno board is designed in a way that allows it to be reset by software running on a connected computer. One of the hardware flow control lines (DTR) of the ATmega8U2/16U2 is connected to the reset line of the ATmega328 via a 100 nanofarad capacitor. When this lin...

Shown here in clockwise order from the lower left are a Duemilanove, a Leonardo, a clone Mega2560 with an extended I/O pin layout from SainSmart, and an official Arduino Mega2560, with an Arduino Nano sitting in the center. Figure 4-3. Comparison of Arduino and clone boards Full-Size Base...
The Nano 33 BLE / Nano 33 BLE Sense is designed as an improved version of the Arduino Nano / Nano Every, featuring the same pin layout to make it nice and easy for DIYers. Both boards have a 32-bit Arm Cortex-M4 CPU running at 64MHz built into their nRF52840 chips, with 1MB of...
