Multiwii and Megapirate AIO Flight Controller w/FTDI (ATmega 2560)

This board features a multiple serial interface as well as a dedicated I2C interface. You can now plug in a GPS directly, and you still have extra ports for other external devices. In addition to that, the new ATmega 2560 has more IO pins so it can both read the PWM signal from your receiver and it has enough PWM outputs to control the ESCs directly without the need to do the PWM signal in software. 

This controller even has a MicroUSB port right on the board, no need to attach an extra FTDI USB interface.

The motion sensing side features a new generation MEMS Gyro, a MPU6050 by InvenSense, which has the MEMS Gyro / Accelerometer sensor on a single chip. There’s also a 3-axis magnetometer and a barometer sensor with a resolution of 0.01 millibar – approximately a 10 cm height difference.

Interested in GPS functionality? Well this is one of the most cost effective ways to get started - simply add a 10Hz GPS module (coming soon) and you’re good to go!
