Key Component in QuadCopter Project

I'm attempting to build a quadcopter from scratch, including the flight controller. I will be using code developed by someone else & enhancing it to meet my needs. I originally thought using an Arduino UNO would be the right hardware, but it turns out to be too slow. I discovered this board while watching some videos & it was easy to see it would be a better choice: 32 bit & a 72 mhz clock speed. There are enough 5 volt tolerant pins to use this board with a 3 cell LiPo battery & the appropriate voltage regulator. Sometimes referred to as the 'Blue Pill', there is significant discussion about it on the Internet. There is a development Add-In for the Arduino IDE, so you can work in a familiar environment. There is also another Open Source IDE, which will allow you to work @ a lower level, which, of course can provide a faster solution. Bottom Line....I hope to use this board for other projects.

It's such an awesome product in a small useful package. I am using a Mac, and I flashed it using an FTDI Serial to USB adaptor in conjunction with the Arduino IDE. If you follow the guides online, it works great, and a lot of the Arduino libraries work out of the box.

STM32 MUCs are great. Cortex M3 is much more powerful than any flavor of Arduino. Easily programmed with ST-Link. Very happy with the purchase.

Board worked for a short moment then shorted out on me. I am giving a positive review because seller had reached out to me to correct the issue. I have already purchased a second board that works flawlessly.
