What is wrong with the STM32F3 Discovery? It has gyros, acceleroter and
magnetometer...

That's why I got the F3, but the F4 has USB OTG which the F3 lacks.
F4 also has a USB CDC (Virtual COM port or VCP) example too, which
the F3 lacks; I'm in the process of building one. Shouldn't be too
hard, starting from the HID Joystick example that ST provides.
I bought it to control a digital radio chip in a hand-held direction
finding sniffer (for which the IMU will know the direction) but I
might wind up adding an RF stage, VFO, mixer and downconvert to 50KHz
to do the rest as an SDR in the F3... maybe.

Interesting. It looks to me like the F3 has this nice fancy sensor and
the F4 just has an accelerometer, or am I looking at the wrong doc about
the F4? I had thought of getting an F4 board since it's a more powerful
CPU than the F3 while the board costs about the same, but the sensor
makes the F3 much more interesting.
From http://www.mouser.com/new/stmicroelectronics/stm-f3discovery/ :
L3GD20, ST MEMs motion sensor, 3-axis digital output gyroscope
LSM303DLHC, ST MEMs system-in-package featuring a 3D digital linear
acceleration sensor and a 3D digital magnetic sensor
Similarly from
http://www.mouser.com/new/stmicroelectronics/stm32f4discovery/ :
External application power supply: 3V and 5V LIS302DL, ST MEMS motion
sensor, 3-axis digital output accelerometer MP45DT02, ST MEMS audio
sensor, omnidirectional digital microphone CS43L22, audio DAC with
integrated class D speaker driver
It looks like the F3 board has the gyroscope and mag sensor, but the F4
has nicer audio stuff.

Good find ! I've ordered an STM32F3DISCOVERY from Mouser for the princel;y sum of �7.54 exc. It has exactly the facilities I was after.
Many thanks,
Boo

The discovery boards are great for the cost, come with built-in STLinkII
USB:SWD hardware. This is
a) directly supported by openocd and
b) can be used later as a general purpose programmer/debugger for your
own hardware
I have several different ones (F2, F3, F4, F1L), a couple just waiting
for a suitable project.

I gotta check this thing out, for it's potential as a fun engineers toy
if nothing else.

The Discovery board seems to have an accelerator but no gyro.

F3 announces
" It is based on an STM32F303VCT6 and includes an ST-LINK/V2 embedded debug
tool interface, Gyroscope ST MEMS, E-compass with accelerometer ST MEMS,
LEDs, pushbuttons and a USB mini-B connector."

I recently bought a $250 dev board for the STM32F4, because I didn't see
that one on ST's site.
Sigh.
I may get one for me, though.
