ST announced their new development board that brings some interesting features on it. Instead of boring becoming standard they included 9-axis MEMS including accelerometers, gyroscope and e-compass. This should be ideal board for balancer or quadcopter developers.
STM32 F3 comes with ARM Cortex-M4 with DSP core and floating point unit. 10 LEDs where eight of them are circle oriented for better orientation visualization. Development board comes with STlinkV2 part that allows easy uploading and debugging programs. Additionally there is second USB port for custom usage. Initial price has been set to $10.90 but it seems that they aren’t available yet.
