Great Little Cheap Board!
I used this board along with its corresponding motherboard in lieu of the much more expensive ST Micro STM3240G-EVAL board at work. It worked great! The clock crystal is 8MHz vs 25MHz on the STM3240G-EVAL, so I just had to tweak the PLL settings to get it to work the same.
The one gripe I had though was that the board uses 2mm pitch square pins and not the standard 0.1" pitch 0.025" square pins, so I couldn't easily just use Arduino wires to connect it to my other peripherals. That's why you basically have to use this with the motherboard to get the right size pins.

Getting Display to Work
It was tricky to get working. Using this website helped a lot: arduino-info-dot-wikispaces-dot-com/LCD-Blue-I2C
I used "I2C LCD DISPLAY VERSION 1" and changed address to 0x3F. Adjusting contrast just right using pot on back is crucial.

Board is Miswired
3 of 4 found this helpful The board is miswired. To get this board to work with an Atmel AVR ISP programmer, PB0 needs to go to MISO pin on 2x3 pin header not the MOSI pin.
