Parts List
From Quadcopter
Here is a list of parts we used for the project.
means we have bought,borrowed or stolen the part.

Frame
- 12x12x800mm Aluminium square tubing, 1mm thick walls.
- 4 x 13x120mm flat bar, 2.5mm thick.
- 4mm bolts and lock nuts.
- 4 x Hacker 20-20 motors or equivalent, the hacker clones are much cheaper.
- 4 x Ground contact switches. The last word on whether we have landed or not.
Electronics
The electronics stack is divided into 6 components.
6 DOF IMU
- 2 x IDG-300, Integrated Dual-Axis Gyro.
- MicroMag3, 3-Axis Magnetic Sensor Module. Datasheet
- MMA7260Q, ±1.5g - 6g Three Axis Low-g Micromachined Accelerometer. Datasheet
- LV-MaxSonar -EZ4, Sonar Range Finder.
- MP3H6115A, Integrated Pressure Sensor.
- 2x LTC1867L, 16-Bit, 8-Channel 175ksps ADCs.
- ARM7 16-bit/32-bit ARM7TDMI core, Microcontroller.
Power board
- Atmel ATmega8, Microcontroller. Datasheet
- ACS756, Hall Effect Current Sensor. 100A
- Voltage divider for battery voltage measurement.
-
LTC1867L, 16-Bit, 8-Channel 175ksps ADCs.we are just going to use the 10bit A/D on the ATMega8. - R-78B3.3-1.0, 3.3v DC/DC-Converter 1A Pin-out compatible with LM78XX Linears. Datasheet
- R-78B5.0-1.0, 5v DC/DC-Converter 1A Pin-out compatible with LM78XX Linears. Datasheet
High level controller
- FOX Board LX 8+32 [1]
GPS
To be decided.
Radio

Electronic Speed Control
-
4x Atmel ATmega8, Microcontrollers. Datasheet -
Hobby brushless speed controller.
We are probably going to use ready made i2c compatible speed controllers. Two types we are looking into are
- Bl-Ctrl v1.2 from [mikrokopter.de]
- YGE 30 i from [yge.de]
The advantage of the Bl-Ctrl is that it's cheap, while the YGE 30 i is nearly double the price. On the other hand the YGE 30 i can supply up to 30A continuous current, but the Bl-Ctrl can only do 10A. So it's going to be a trade off between price vs power.
