“If you need headers and/or USB cable, this inexpensive kit will help. Love the micro-USB to USB plug.. looks like nothing but lets you put the Pico into a USB slot easily.”
“Provides all the additional parts needed to make the Pico fully useable. It is convenient to have the headers soldered in so that it can be plugged into a solderless breadboard for prototyping projects prior to committing them permanently to PCBs.
Purchasers need to be aware that they need to be able to solder to make use of these parts.”
“The kit contains all the headers I needed to get my Pico 2 W up and running. The tin can, apparently, be used to mount the board though I'm not sure how that works.”
