Datasheet

If you'd like to do more advanced development, trace-debugging, or not use the bootloader, we have the SWD

interface exposed.

You can use any 2x5 0.05" pitch SWD interface to connect. We suggest a J-Link. Since the SWCLK pin is shared

between the NeoPixel, and the bootloader takes control of the pin, you need to reset the board

right before

beginning

debug. OpenOCD and some other debug interfaces may not be able to do this. That's why we really really suggest a

JLink!
