Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're ...

Since Linear Tech is also a power supply chip company, they beefed up the power supply on the board, using a switching regulator to replace the linear regulator on the Arduino. This means you can get ...

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.

Having trawled though Arduino’s just-released Uno R4 literature, here are the Uno R4 WiFi and R4 Minima in a nutshell: Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO ...

The 16u2 is normally used as the Arduino Uno’s USB interface. The only external hardware needed is a single 120 ohm resistor. The original Apples had cassette and speaker interfaces.

The small Arduino development board offers a fantastic alternative to the larger form factor of the Arduino Uno and even the Arduino Nano. Specifications of the Atto are listed below and the board ...

Here, ours was COM3 (Arduino/Genuino Uno), but yours may have a different number or name, depending on the microcontroller you’re using.

If you have the answer, let us know in the comments below. Continue reading “Arduino Serial Vs SerialUSB”→ Posted in Arduino Hacks Tagged Arduino DUE, Arduino Uno, USB serial, wireshark ...

In comparison, the Arduino Uno, Leonardo, and Mega 2560 boards all have theoretical ADC speeds of 15 ksps. Caption Dual USB inputs and 12-bit analog I/Os.
