General Purpose Controller

There is often a need for a general purpose controller, easy to hack and adapt for simple control tasks.

For example, watering plants and monitoring soil moisture for only a few summer months. Or a rig to assist with wire handling, such as cutting a large quantity of wire using a pulley with an optical sensor to count wire length.

The General Purpose board was created to have:
  • 1.4" color TFT backlight graphics display
  • PWM servo outputs (2)
  • higher voltage motor outputs (2)
  • touch sensor (button) inputs (3)
  • switch input connections (3)
  • RS-485 to allow for networked control
  • easily distributed 12VAC power
  • prototyping area for additional components
  • support for Teensy's real time clock

This may become a product in the future, since it meets a 'turn-key' need. For now, it's a physical experiment to explore different uses and a base to explore further development to meet wider needs.

Under the 1.4" display, are the power supply and mosfets for motor control.

The Teensy 3.2 board supports a real time clock. A coin cell socket is mounted on the back of the board to keep time during power off.
