STM32F4DISCOVERY as future promini replacement candidate

[msev]

Although dongs made an excellent and very affordable Naze32 board (with all the sensors already on it) a lot of guys have seperate IMUs with different sensor combos at home and would probably like to have their stuff in use also in 32-bits. Here's where STM32F4DISCOVERY could come into play. Regarding price, just for reference Farnell.de has it for 15.44 euro , Newark has it for 19,04$ so its pretty affordable IMHO.

The cost and performance is right, only the size bothers a bit, but I think we can live with it? Or are you guys looking at every little bit of excess weight to hunt down?
But I'm not an expert so maybe there are some other downfalls to this board...Here is where you guys pinch into the discussion.

Here is the datasheet if you want to read a bit more: http://www.st.com/internet/com/TECHNICA ... 039084.pdf

PS: Dongs I know its too big

Well, the pro mini is not going to be replaced. Not so soon anyway.
Only the code ported to new architectures while maintaining back compatibility. Some features may not be supported by the pro mini (just as today some features require a mega).

That board is huge 97*66mm, and it does not even have mounting holes! Weight is usually not that much of a problem but mounting it (+ sensors board + GPS + optional OSD) on a medium size quad is going to be a mess.

I ordered some of the STM32xx microcontroller

F4 and F100RB

Just for info guys, this dude has just ported OpenPilot to STM32F4 ( Discovery board ), and MPU6050 PiOS is done.

This is interesting, thank you for sharing.

there is already an implementation of MultiWii

much better usage of space

It seems a few F3 boards are available in europe at farnell and RS UK

does this mean you can't order them to japan?

[timecop]

I got a friend in UK to pick me up a couple.
Also, I've written the ADC stuff we talked in email.
Just gotta test it and commit.

Hope I'll be able to get ahold of one of those F3DISCOVERY's, I think I should rename this thread.

Yes i know that, its great

How about a micro-quad (ARF - Brushed) based on a STM32?! Looks like the thread title has been validated. http://www.goodluckbuy.com/fly-mini-mic ... 5883l.html

Edit: Just to qualify the above - actually that model isn't the F4 with FPU, but a F1 without FPU... so perhaps not that good evidence... still, nice seeing 32bit make it onto "toys" like these.

Hi guys!

I shared port of BaseFlight-20131126 (with MultiWii 2.3 features) for STM32F4-DISCOVERY board + GY-86 sensors board (mpu6050 + hmc5883 + ms5611).
Project was created for CooCox CoIDE 1.7.5 (with toolchain arm-none-eabi-gcc 4_7-2013q3).
