The shorty socket header assembly method has so far been the most compact option. What if there was an even skinnier option? Turns out there is!
This page assumes you have already soldered standard male headers to your Pico. If you have not, please return to the Pico assembly page and follow the steps there.
Once you have the standard male headers soldered to the Pico, it is possible to solder the PiCowbell Proto directly to the Pico. This results in a super compact little sandwich. Be aware, however, that this method means you cannot remove the PiCowbell without desoldering it.
Follow the steps below to solder your PiCowbell Proto directly to your Pico.
Ensure the PiCowbell is oriented correctly before beginning assembly. The PiCowbell should be top-down, so that you are looking at the bottom of the Cowbell. The STEMMA QT connector should be on the same end as the Pico USB connector, and the reset button should be on the opposite end with the Pico debug pins.
The PiCowbell pins must match the pinout on the Pico.
Remember, the pins are labeled on the bottom of the Pico. In this case, that works well because they are labeled on both sides of the PiCowbell, allowing for direct comparison before attaching the Cowbell to the stacking header assembly.
Press the PiCowbell onto the pins sticking up from the standard headers on the bottom of the Pico. There will be a small gap on both sides due to the height of the reset button and STEMMA QT connector being taller than the plastic spacer on the Pico's standard male headers.
Solder the pins on each end of each standard header, so that the opposite four corners of the PiCowbell are soldered on. Ensure that you maintain an equal gap on both sides so the PiCowbell is horizontally straight.
