It work very well. Programming is easy using stm32duino with PlatformIO. Flashing is easy using NRST and BOOT0 with a single finger to activate DFU over USB. Debugging is simple using serial port over USB.
One important thing need to be noticed: if you can't see DFU firmware after doing the DFU boot sequence, warm-up the stm32 chip with your finger. It need to be at least at 25 degC to work.
Even with this DFU issue, it stays a very good product.
EsmarraHey,
Could you elaborate on this "using PlatformIO". I'm having trouble flashing this F4.
Please share .pio settings and how you upload. i.e connected via USB-C or not, and which button to press(Boot\Reset\Key).
Thanks!
