Stm Morpho Header MicroPython extention board
This small board connects to the bottom of STM32 Nucleo-64 boards trough STM Morpho Header.
So fits like a sock. Board has microUSB, SD card socket and SPI flash memory chip. Clip the board to any Nucleo64 board download corresponding DFU file and you have fully functional MicroPython board.
I made definitions for NucleoF401RE, NucleoF411RE, NucleoL476RG to use with DFU-SOCK board and tested them.
I have tested as well different spi memory chips. Adesto and Winbond from 8 Mbit to 128 Mbit work fine.
