AeroQuad Mini Shield v1.0 soldering procedures

Here’s the complete set of components for the AeroQuad Mini Shield v1.0 for Arduino Pro Mini 5V. Included in the picture is the AeroQuad Mini Shield v1.0 board, the breakout pins (98 total needed), the SparkFun 6DOF breakout board (with ADXL345 accelerometer and ITG-3200 gyro), logic level converter board, SparkFun FTDI Adapter, Arduino Pro Mini 5V, two resistors (R3 = 7.5k and R4 = 15k), two blue capacitors, two diodes, and a 3302 3.3V, 250mA, TO-92 package low voltage dropout regulator.

A note on electrostatic discharge (ESD)

It is important to take some care when working with the electronics (sensors and the Arduino) in order to prevent them from being damaged by ESD. Here are some recommendations:
  • Ground yourself before touching the electronics. This can be done by touching a metal appliance which is plugged into an electrical socket.
  • Work in an environment where there is less chance of ESD developing, such as on a concrete floor of a garage. Avoid carpets and plastic tables
  • When not in use, store the electronics in an ESD protective plastic bag.

Breakout pins to the sensors boards and Arduino

Don't forget the two holes in the middle of the Arduino Pro Mini (A4/A5) like we did in these photos! These pins are essential for the functionality of the sensors!

Break the breakout pins into sections that correspond to the number of holes in the sensors and Arduino Pro Mini 5V.

Insert the short ends of the breakout pins through the bottom of the sensor breakout boards/Arduino Pro Mini and solder them on the top. On the end of the Arduino Pro Mini, insert the short end of the pins from the top, allowing connection to the FTDI breakout board and solder from the bottom.

Resistors, Capacitors, Odds-and-ends to Shield

The two resistors that come with the shield are a 7.5k and 15k ohm. Place them into their respective spots, solder them from the bottom, and trim off the extra wires. The two black diodes have lighter ends than the rest of their respective color, make sure those match up with the indications on the mini-shield. The transistor's pins may not be in a triangular shape like the pin-holes on the shield. Bend the center pin on the transistor forward slightly to line up with the shield hole. (Be careful not to bend it too much, or too many times, as it will weaken the strength of the pin and may break)

Attach Sensors to Shield

Insert the sensor board, logic level converter board, and the Arduino Pro Mini into the shield from the top and solder them from the bottom. Again, ensure that you didn't forget the two pins in the middle of the Arduino!
