I can see the rational for having pins 360 degrees... but for working on a breadboard, it creates the same issues as PICO has. I prefer the DIP pinning, like the espruino_wifi. As a compromise for 360 pinning: if the short side ones are for programming, connecting to USB/Serial, that may work.
Putting headers 'downwards' on long side and headers 'upwards' on short sides, breadboard use is still possible - or - headers on long sides and wires - 'flexible headers' - with tinned (pins at the) end on the short sides: see @Gordon's breadboard friendly version of PICO, w/ picture).
re espruino_wifi:
A) What is the rational to put A8, A10 not on the outer line of pins?
B) I wondered if there is space left for 'wiring' and pads for serial FLASH / EEPROM / RAM / FRAM / MRAM ... since available memory is always a challenge...
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.
