Text Notes 550  3800 0    60   ~ 0
These two pullups likely want to be fairly\nmid-trace on the board, rather than directly next\nto the STM32 itself.
Text Notes 7300 5350 0    60   ~ 0
There is decoupling on-board on the DAISY-24\nso these capacitors are only for stabilising the\nLDOs.
Text Notes 8100 6400 0    60   ~ 0
Note, this pin header might need to change to a 2mm or even a\n0.05" pitch rather than the 0.1" pitch footprint currently used.
Text Notes 550  6700 0    60   ~ 0
Maybe use a resistor rather than\ndirectly linking TCK and RTCK?
