"Hello Patrick,
I have BBCore + My own Baseboard (built for 9€) + sensors (sonar+pressure+imu+optical flow) + 2.4GhzModule (with RSSI) for only 120€. I will share some pictures later.

BBCore should be used with customized Baseboard.

Thanks."

"Hi,
I think BBCore is best than BBBlue, BBCore is samall and it can be optimized. (http://beaglecore.com/)
Adding sensors (like IMU) to the main board is not good, we should have hardward layer (Sensors, RF, ...)

The good thing is the OSD335x which…"

"i used my own program based on open source solutions.
I connected PRU 30 pin (i used only 8 pins)  to an isolator ( i tried different isolators).
the same issue like :

"Hi,
the big issue with BBB the power management. i have lost more than 3 boards when i tried to use PRU/PWM.
I'm using PI A+ instead!
Thanks."

"6 seconds seems good, i build a mini kernel image (Yocto) it takes 4 seconds with ssh server."

"Thanks for sharing PWM info. i'm using ehpwm driver i wil share it later.
What is the performance of Spi (SpiDev)?
Why the choice of Debian Wheezy, how time takes to boot?"

"thanks. it seems that you use PCA9685 PWM controller instead BBB intrenal one?"

"Hi,
which spi/pwm drivers are used (samples or source code).
i'm creating one like Arduino... (in progress)

thanks."

"The RCTimer ESC are the best

"Hello,
impressionnant!  did you use the audio link to send data?"

"The IDE work only on windows!i use eclipse with arduino plug-in, you can use it on windows/linux. 
Eclipse is a powerful tool, i used it with java, c++, android, ..."

"I used MPU-6050 with Gumstix (I2C at 400khz), i had  latency to get all data in 1ms,  i tried to make my breakout but the soldering is difficult.
Why Diy Drones not purpose a breakout for these sensor?"

"It's a great sensor, i'm looking for SPI Version.
Thanks."
