IMO: even if you are moderately knowledgeable with 8-bit Arduino, you should still move into the STM32 world with the Maple Mini. First it is affordable. Second, it is affordable and if you smoke the first one, you were smart to buy a second one. There will be times when you cannot decide if you have a hardware problem or a software problem, that second board is a tie-breaker.
Aye, that's the idea. It's gonna be more useful to me to have a spare board than a TI LanunchPad / ST Nucleo taking dust in a drawer. Also a cheap logic analyzer.
There is great knowledge in the writings of this board, in this regard, Google is your friend. If you need to find something and the forum search fails you, try using the Google search by site feature. For example, key phrases followed by "site:stm32duino.com"
Thanks, I've been reading around stm32duino / Mbed / LaunchPad Energia/ *RTOS as I'm getting into STM32 and there's a lot of sparse info.
The fact that we can get into that by an Arduino-Wiring path is splendid.
Use a decent 3.3V power supply which is well-filtered. I would shy away from AC wall plugs that are 5V used for charging cellphones, etc. [CUT]
That's good advice thanks, I actually have some of those wall 3-12v adapters and the breadboard adapter, and a modified PC-PSU for charging my lipos.
I was looking at something like this: http://www.ebay.it/itm/ALIMENTATORE-STA ... 1c490a15a4
: would this do the job?
Wait, maybe can I use may PC-PSU with something like http://www.aliexpress.com/item/New-DC-D ... 85464.html
to stabilize the output?
These days, DC-DC buck and boost units are around $1 - $2 each and are ideal for battery powered projects. If I am designing for 3.3V battery project, I generally use a 3.2V LiFePO4 cell (search as the topic has been discussed here.) 2-AA alkaline batteries are going to under-power your project, 3-AA will be the minimum to properly drive a 3.3V DC-DC unit, but 4-cell alkaline (~6V) is IMO a better choice to feed the DC-DC buck unit. The buck units are around 92% efficient, so it is far better to use them to manage the power than a linear regular or a string of 4001 silicon diodes!
For running my Arduinos on lipos (I put them on RC airplanes, I don't have any LiFe, yet they seem better fitted for the job) I use some http://www.aliexpress.com/item/Mini-DC- ... eb201560_9
Well actually an Arduino Mini Pro or a Attiny85 goes directly to the RX 5v as they are inexpensive and weight / power is king.
Welcome and I hope you have a good time when your Maple Mini's arrive.
Thanks for the warm welcome and for the links!

, the BluePill is like 10 days away: I have some time to read through the doc.
