He used the same connection scheme, but went with an edge connector for the USB instead of using a mini-B jack. It’s pretty impressive to see his prototyping work with the 16-pin QFN package.

Adding USB functionality to your Arduino projects used to be a pain, but thankfully, the V-USB project came along and gave your ATMEGA328 the ability to control the USB lines directly and mimic sim… ...

Project schematic As seen in the above schematic, a 5-V DC supply from the USB connector (USB) is routed to two 10-Ω/5-W power resistors (R1 and R2) through an SPST switch (S1) followed by an SPDT ...

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.

At the rear is a standard USB-C socket for a USB-C cable to take signals to the test system. Rated voltage is 20V ac or dc, and rated current depends on the pin location: 1.25A A1, A4, A9, A12 B1, B4, ...
