STM32 F3 Discovery dev board includes some extras

ST Microelectronics keeps kicking out development boards to show off their new ARM processor line. Yesterday they issued a press release announcing the STM32 F3 Discovery Board. As their naming scheme implies, this carries an ARM Cortex-M3 processor, but compared to the F0 Discovery board (which we loved) it’s got several extra goodies built into it.

We took a look at the F3 Discovery product page and it doesn’t look like you can order these quite yet. But click-through to the pricing and you’ll see they’ve set it at $10.90. Digikey lists the board at that price point, Mouser lists it at about $16, but neither supplier has any available. We also didn’t see a link for free boards like when the F0 model was released. If you do come across a giveaway link please tip us off about it.

Okay, now let’s discuss those extras. We think this dev kit could be used as an IMU for applications like a quadcopter or a self-balancing robot. That’s because it has a gyroscope and an accelerometer. It’s also got ten LEDs, eight of which are arranged on that white circle. We’d guess that layout is for displaying orientation data from the IMU sensors. There’s also a second USB port to use when developing USB applications for the chip.

Like the other boards in the Discovery family this has the STlinkV2 built-in to use as a programmer. We don’t know if OpenOCD has support for the F3 chipset yet, which is what we’ve been using to program STM chips in a Linux environment.
