This doesn’t affect the largest program size you can run - that’s down to the program memory size, but if you want your application to use graphics and sound samples or other data resources then the Feather is the way to go.

This is because the Feather device has an 8Mb flash chip, while the PICO only has 2M. Note that the Feather has much more storage space. Above you an see what Windows thinks of a PICO (called CheesBox - oops) and a FEATHER. If you use Circuit Python they appear as external usb storage devices where you can drop the files. Data Sizeīoth devices use an EEPROM (or ‘flash’) memory chip to store program code and data. Loading a 500 line Python program left me with a reported 130K or so free so there is scope for these devices to run quite chunky amounts of code.

If you install Circuit Python or MicroPython you end up with around 200K of free memory as reported by my tiny memory size reporting program: Program Sizeīoth of the devices use the same chip, the RP2040, which has 264K of internal memory for code and data storage. On the Feather you can solder a socket on to connect the debugger, on the PICO you add some pins.

Both have connections for hardware debugging. The biggest difference is that you use a usb-c cable to connect to the Feather and a micro-usb cable for the PICO. They are obviously different (for a start one is black and the other green) but what other differences are worth knowing about? Programmingīoth of them are programmed in exactly the same way. The Adafruit Feather and the Raspberry Pi PICO are boards based on the RP2040 processor from the Raspberry Pi people.
