Description
Project Overview
Designed a versatile Micro Computer to be used in a Multitude of Projects. Some of the projects will be used for
- To control a Drone, a Robot, an RC Plane with Vtol, And a Switch for outside lighting. To make a Weather Station, To be Used to control a 3d Printed Robotic Arm, And of course for my High Power Rocket. I aim to make the design as flexible as possible so I won't have to redesign a new Controler for each Project.
Principal Parts of The Computer:
Power:
Power in is via a 12v lipo Battery connected to Battery IN
Convert 12v to 5 volt. The Teensy convert the 5v to 3 volts
Battery Voltage Test: Test the Voltage of Battery
Screw Terminal
Main ARM: Power ON Battery to PCM
PyroArm: Permit 12volt power to Pyros
BattOut: 12v OUT to be used for outside Devices
Battin : Main Power Input from Battery
5vOut: 5 Volt OUT to be used for outside Devices.
3.3vOut: 3 Volt OUT to be used for outside Devices
Servos:
Servos Control – control Direction, and or Actuators to open or close something else.
IN1, IN2, IN3, ESC: Use to control the Speed control Of an External device " Like a Drone"
Buzzer:
Alert to Status of Device or Firmware Execution Steps
Sensors:
Different sensors to Get Positioning, Speed, orientation, and Location.
We are using : AltIMU-10 v6 Gyro, Accelerometer, Compass, and Altimeter (LSM6DSO, LIS3MDL, and LPS22DF Carrier)
Pyros:
A quick burst of voltage 12v 2A is used to control the firing of the Pyros.
Pyro test:
Continuity testing to determine the Pyros state.
Telemetry:
Send Data, and receive Data from external sources via Lora Radio at 915 MHZ
Expansion Connector
Expansion Port: Permit adding Companion Board to add functionality.
Teensy 4.1 has Native Pin connectors for the following.
USB: USB Host Connector. Use to add a USB device.
Ethernet: to connect an Ethernet Adapter for future use
