My own Flight Controller

My own Flight Controller

So I been trying to build as small  quadcopters as possible for a while now.
So I tought that the next step would be to design my own FC med integrated brushed motor drivers for a hex quad.

Been using the micro multiwii for some time, but after I started using the Naze32 for my 250 quad I was really looking for a better version of the micro multiwii, with no luck.
So after some time and searching I did my own version that is HW compatible with Naze32

I just finished the cad, and will be ordering a few boards tomorrow, will be fun.

I named it Raze32

It has the same HW as the Naze32 without the PWM7 and PWM8.
But I have added 6x 7,5Amp motor drivers for DC motors. the board can be assembled with or without the DC motor driver. So I can make a real hex micro, and still use the board for my bigger quads

Other then that there is a SBUS inverter that is connected to CH4 on the board.
2 open drain 300mA ports, so I can control leds direct.

the board is only 20x38mm and 0,8mm thick.
The motor driver takes 9mm of the lower part of the board, so it could be 20x29mm without the motor drivers.

the board has 3 voltage regulators, one extra for the external radio RX.
The MCU and MPU-6050 will be tested with 3v and 2.8v regulators, to see if it works Okay with lower voltage.
So there should be no problem with low voltage drop on from the battery if I use 1S.
It is designed to take 10v, so I can test 2S on the micro copter projects

The side pads is designed for standard 2.54mm pin headers.

Really looking forward to test them out
