I bought this board to develop some prototypes on it, I liked the pinout layout and the tft is really nice. I had some problems downloading and debugging, the problem was on the NRST line. I resolder the resistor R21, diode D1 and removed the capacitor C15 (another time I'll put another capacitor... nah I'll forget). If has problems check the voltages, it’s probably some bad solder joints. Although the delivery was very fast, it's a big trip from China to Brazil, so I decided to make it myself. Even so, my only complaint with this card is that the VBAT pin is connected to the VDD. Didn't even need a CR battery socket, would be nice if they just made this feature available on a pin header.
