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:
-
Pololu 5V Step-Up/Step-Down Voltage Regulator S7V7F5, on bottom, using 1-2mm chisel/bevel tip.
-
28AWG silicone-insulated wire for hover-deck, protruding from bottom, using 0.2-0.8mm fine/conical tip.
-
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).
-
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.
-
220Ω resistor, on bottom, using 1-2mm chisel/bevel tip.
-
LED, on top, using 1-2mm chisel/bevel tip.

Questions
How big is the Hackflight PCB?
It measures 120.5 × 73.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackflight use?
40 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hackflight KiCad files?
From the simondlevy/Hackflight repository on GitHub, at the commit this page was made from: the board is kicad/tx/tx.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackflight design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
