To be considered for V2

• SD slot
• Pin header with SD/SPI signals (Monideth Pen, Hlide Fremen)
• Input fuse (SMT chip fuse - Optional/Bridgeable - Keirf)
• USB power switch (Optional/Bridgeable - Keirf)
• Replace resistors with 4x1k smd resistor arrays to reduce number of elements and pcb space (Paweł Mandes)
• Subsitute an open collector buffer, instead of the existing resistor / fet combination, that will save a bunch of components. I used a 74ls07, but with a small change to the ff code you could use 74ls06 too (Phill Harvey-Smith)

SWDIO and SWCLK for ST-Link, please (pins 46 and 49 of the MCU) :)

at32f435 for that extra performance and RAM ?

[edit] - I just learned it should be pin-compatible with the F105, c.f. keirf/flashfloppy#874 (comment)

Done in current devel branch, test pending.
