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.

To use it as such, you need a USB cable and a 5V power source. In the case of the Arduino Nano, a mini-B USB cable is required. The power source, on the other hand, can be a powerbank, a phone ...

Connectors are all different (USB) and in different positions (POWER jack, I/O headers). Arduino UNO shields won’t work. Kind of like calling a VW bug a Lamborghini because they both have four ...

USB 2.0 full-speed (able to simulate a mouse or keyboard to a host PC). Op-amp Capacitive touch sensing possible. Features only on Uno R4 WiFi (right) and not on Uno Minima. Wi-Fi 2.4GHz 802.11b/g/n ...

For instance, on the Nano there is an FT232RL between the USB connector and the microprocessor (on an Arduino Uno board, a small ATMEGA8U2 is used instead of an FTDI chip, but the concept is the ...
