Secure M2 nylon machine screws

Before soldering on any of the components, you'll need to decide how you're going to mount the PCB to your airframe. I've also used VHB tape, which doesn't require screws, but for a cleaner build the PCB provides four mounting holes in the popular 26x26mm diamond configuration, for use with M2 nylon machine screws. You secure these screws temporarily with nuts before using a rubber grommit for vibration dampening.

BOM, in order of soldering

Note: I recommend using Scotch tape to mask the pins you're not currently soldering, and doing a continuity check for bridges/shorts after each step:

1. Pololu 5V Step-Up/Step-Down Voltage Regulator S7V7F5, on bottom, using 1-2mm chisel/bevel tip.

2. 28AWG silicone-insulated wire for hover-deck, protruding from bottom, using 0.2-0.8mm fine/conical tip.

3. SHUTTLE BOARD 3.0 BMI088, on top, using 0.2-0.8mm fine/conical tip. To avoid soldering a bridge (short circuit), you should solder only the six indicated pins (3V3, GND, SCL0, GD, SDA0, 3V3).

4. 28AWG silicone-insulated wires to 4-in-1 ESC, protruding from bottom, using 0.2-0.8mm fine/conical tip. Most 4-in-1 ESCs come with this connector, or you can build one yourself using a kit like this.

5. 220Ω resistor, on bottom, using 1-2mm chisel/bevel tip.

6. LED, on top, using 1-2mm chisel/bevel tip.
