You’ll need a way to connect your programmer to these points (also called “pads”), such as: On the Nano 33 IoT, the two main pins for this interface (SWDIO/SWCLK) is available via test points on the bottom of the board, near the Arduino logo: To burn the bootloader on Arduino Nano 33 IoT, we need to use the SWD (Serial Wire Debug) interface. Contact us before soldering if your board is under warranty. Note: Improper soldering can void the warranty.
