Note:Switching to Arduino code from MicroPython will delete your custom MicroPython programs from the 3pi+ 2040. Make backup copies of your MicroPython code before uploading Arduino code to the robot.

[Hans Peter] wanted to move away from using full Arduino boards in his projects. One of the components he rarely used after the development stage is the USB hardware. Once the firmware is flashed to ...

The LUFA version is 100807, as in the hardware-pinoccio repository. This version is required for both DFU and USB serial firmware. The arduino-usbdfu directory contains the DFU bootloader on the 16U2 ...

The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature isn’t ...

The project illustrates an old Arduino USB board being hacked by finding the right pins and stringing a capacitor between the serial connector and the reset line. One side of the capacitor connects to ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.
