Multiwiicopter MultiWii Copter MWC Controller Board + FTDI Basic Breakout

Multiwiicopter MultiWii Copter MWC Controller Board


The MultiWiiCopter is another multicopter based on a Wii Motion Plus extension and an Arduino pro mini board. This multiwii MWC board adopts ATmega328P chip with LLC and 3V3 voltage-stabilizing circuit. With some interfaces which is convenient for connection and DIY,such as HVI2C (connect to Wii Nunchuk sensor), LVI2C(connect to other digital sensor), GPS, LCD, data transmission, Bluetooth TTL interface.
This MWC board can now handle several different configuration: tricopter, quadricopter, Y4, Y6, hexacopter, octocopter.

Features:
- Fixed hole distance: 45mm(compatible with kkmulticopter frame)
- Hardware support: compatible with standard servo and most standard ESCs(like XXD Hobbywing ESCs)
- Remote Controller: compatible with any receiver(4 channels mini, even those with a single PPM sum signal)
- MWC Size: 5cmx5cm

Sensors Configuration:
Low Level: WII MP + IDG600 or IDG650,ITG3205
Medium Level: 1.WII MP + BMA180, BMP085
                      2.L3G4200D,BMA020 BMP085
High Level: ITG3200,BMA180,BMP085,HMC5883L or 9DOF IMU

FTDI Basic Breakout - 5V USB FT232RL

This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND, green is DTR. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.

There are pros and cons to the FTDI Cable vs the FTDI Basic. This board has TX and RX LEDs that allow you to actually see serial traffic on the LEDs to verify if the board is working, but this board requires a miniB cable. The FTDI Cable is well protected against the elements, but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.

This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro boards and LilyPads use this type of connector.

One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). This board ship default to 5V, but you can cut the default trace and add a solder jumper if you need to switch to 3.3V.
