Is there any way else to extend the FLASH

Post by Antonio » Tue Mar 24, 2020 7:52 am

The pyboard do have a SDcard, but when i use the pyboard in a new PCB in my project, the SDcard is a bit too BIG.

I want to change the SD to a SPI FLASH, but in the MicroPython downloads links there is no DFU like this,so I can not do that and have to use the SDcard.

so I suggest to make a new pyboard version, It has a SPI flash to extend its memory.

Hi,

There is in fact a new version of the pyboard that has (two) onboard SPI flash parts -- the Pyboard D.

It is also possible to use external SPI flash with the Pyboard 1.x if you connect it to the SPI pins either on the X or Y bus. You can do this entirely in Python (i.e. with the stock firmware), but it's also possible to build a custom board definition that does this in the firmware.
