- Excellent value for money Review by Roger
Value Quality Price
There should be no need to press the 2 buttons before upload. However I have notice the board seems to need to be reset after upload, using the reset button, otherwise the USB Serial device doesn't get activated.
I'm using the Arduino 1.6.3 IDE with files from my GitHub repository https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki and it works fine.
It would have be an even better board if the STM32F103RB was replaced with either the STM32F103RC or the STM32F103RE , as both of these devices have DAC's but the RB version doesn't :-(
Never the less, this is an excellently well made board and at the sale price of $13 for which I bought it, its excellent value. (Posted on 4/14/2015)
- Pretty Good Board Review by Weston
Quality Price Value
As Carlos L. pointed out, the buttons are a bit inconvienent, but this is due to the Maple bootloader. Once I get my openocd board, I'm replacing the bootloader all together.
If you're interested in ARM & don't care too much about Arduino software, it's a nice board that enables quick prototyping. (Posted on 12/10/2012)
