Until @allObjects is able to respond, some links to peruse to assist in that insight:
'unsure what you mean by hooking in a PICO to the Decaware module'
Although I'll defer to his response, I believe the intent would be to create code on a working Espruino device, then start/build communications to the other development board before actually tackling the task of getting it all working on that board.
The Puck is a bit limited on I/O but might be suitable depending on the envisioned working project requirements. See the fifty or so tutorials there.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

IMO easiest device to get started with - just plug into USB port and go: (see heading Pinout)
Sample instructions connecting a device: (basic accelerometer)
Tutorials - loads to observe:
Communication UART - UART
A bit advanced at this point, but a track you might be on
