Crius All In One Pro is a grown-up Crius SE

Need a new MultiWii flight controller, but want more serial ports and extendability? The Crius All In One Pro (or AIOP) is there to fill the void. Full technical specs of this interesting FC coming up after the break.

Our review of the Crius SE Flight Controller is online for barely a month, and already Crius have released the successor, the Crius All In One Pro.

This board features all the good stuff of the Crius SE, but adds multiple serial interfaces as well as a dedicated I2C interface. While you needed to buy a I2C interface board to get GPS working with the Crius SE, 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. In our opinion, that’s a huge improvement and worth more than having a 32-bit microcontroller that still has to emulate stuff like on the Rabbit. It even has a MicroUSB port right on the board, no need to attach an extra FTDI USB interface.

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

Best of all, the All In One Pro is still fully compatible with MultiWii as well as MegaPirate flight firmware.

The price is a bit over $60 at

This is quite an exciting board, if you are interested in GPS functionality this is one of the most cost effective ways to get started. Just add a 10Hz GPS module and you’re set.
