The Tic T500 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates an MPS MP6500 driver, and male headers and terminal blocks are included but not soldered. It can operate from 4.5 V to 35 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (or 2.5 A max with sufficient additional cooling).
Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- TTL serial
- A simple serial data connection that uses microcontroller logic-level signals rather than computer RS-232 voltage levels. It matters because the camera can connect directly to many microcontroller pins or a USB-to-TTL serial adapter, but not safely to an old-style RS-232 port without conversion.
