Step 4: Clean up the connector by adding some heat shrink, plug it into you programming Arduino and you are set to go. This is the best way to use your Arduino as a programmer. It allows you to use ...

You could be forgiven for thinking that this is a QWIIC-like pinout; given that this connector is marked “I2C”, one could argue they’ve been tricked, backstabbed and quite possibly, bamboozled.

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Keeping the pinout, voltage and form factor unchanged from the UNO R3 ensures maximum hardware and electrical compatibility with existing shields and projects while allowing the UNO R4 boards to ...
