Description
Logic Connections
There are two processing units in the drone launcher: Teensy 4.1 and Odroid C2. These two communicate over serial using a micro USB cabel. The Odroid is also connected to a Rajant radio using an ethernet cabel. The Teensy is placed on a PCB which connects it to all the peripherals.
List over PCB connections:
- Limit Switches (labeled BTNS FxRx)
- Led Dtrip Drone Indicator (labeled LED DRONE)
- Arming Switch (labeled ARM SW)
- Menu Buttons (labeled MENU BTNS)
- Led Strip Battery Indicator (labeled LED BAT)
- PWM Servo Signals (labeled SERVO Fx)
- GPS connector (labeled GPS)
- LCD connector (labeled LCD)
- IMU connector (labeled IMU)
Please refere to the pcb schematic to figure out the pinouts of the different connectors.
Power Connections
A 6s LiPo battery is used to power the system. This power goes though a 15 A fuse and a Relay. The Relay coil is connected to a emergency stop button and a key switch. If any of these are not turned no the system will not have any power. After going though the relay the power is distributed to the different devices.
Power Devices:
-
Teensy PCB, connect battery to XT60 plug
-
Odorid, 5V@2A needed, connect micro usb plug from switching regulator
-
Rajant Radio, PoE 8-60V?, connect ethernet cabel to battery voltage
-
Servos, 6V, use step down regulators to provide power

Questions
How big is the Drone Launcher PCB?
It measures 117.9 × 75.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Drone Launcher use?
36 parts, built around the TSR 1-2450 and TEENSY 4.1. 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 Drone Launcher KiCad files?
From the TorBorve/Drone-Launcher repository on GitHub, at the commit this page was made from: the board is electronics/drone_launcher.kicad_pcb and its schematic electronics/drone_launcher.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Drone Launcher design in my own project?
Its repository states no licence, so its author keeps all rights: ask TorBorve before reusing the design.
