Overview
Flightime is an open-source printed circuit board by RishitJain-dev, from the RishitJain-dev/Flightime repository on GitHub. It is a 2-layer board of 61.8 × 38.8 mm with 30 parts on 35 nets, routed with 285 tracks and 43 vias.
It is built around the AO3400A and 220UF 10V 5*7. Its parts include 8 resistors, 6 connectors, 4 diodes, 4 transistors and 2 capacitors. It belongs with the robots and motor control boards and the ESP32 boards of this library.

README
README.mdFlightime - Quadcopter
Flightime is a custom designed drone with a PLA Aero frame, 4 8520 brushed motors, and a PCB flight controller with a OV2640 camera mounted on the XIAO ESP32 S3 SENSE
Weighs: 132.6g
I designed this as an example project for Lift Off, where you design a drone, and get the components to build it and if its a great project, then even a drone controller!
Features
- OV2640 FPV Camera
- Bluetooth and WiFi capabilities
- < 150g
- Power Switch
- 8520 Brushed motors
- $200 total price (including tools!)
PCB
The PCB was made in KiCAD! It has:
- GY-521 gyroscope
- XIAO ESP32 S3 sense
- Various resistors
- Various SMD & TH capacitors
- SMD MOFSETs
CAD
The CAD was designed exclusively in Onshape. The 2 parts fit together with 4 M3 screws and nuts, it doesn't require any heatset inserts, you screw directly into the PLA.
There are cut-outs in each piece so that wires can fit through. This is a pusher drone, the motors are press fit and the propellers face towards the ground.
Assembly
Use the schematic diagram on Kicanvas to solder one side of the wires to the board before assembly. Then place the board, mount it using the screws and nuts and take the wires to the motors and solder the other side there.
Firmware
We move by slowing down certain motors and speeding up others, this causes it to lean and tilt towards the direction its meant to be going, and begins to accelerate. In the final firmware, it will be controlled through bluetooth on a computer or phone.
Renders
Here are some renders I made in Onshape!

Questions
How big is the Flightime PCB?
It measures 61.8 × 38.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flightime use?
30 parts, built around the AO3400A and 220UF 10V 5*7. 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 Flightime KiCad files?
From the RishitJain-dev/Flightime repository on GitHub, at the commit this page was made from: the board is PCB/Flightime.kicad_pcb and its schematic PCB/Flightime.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flightime design in my own project?
Its repository states no licence, so its author keeps all rights: ask RishitJain-dev before reusing the design.
