T51 Microcontroller Board
Add USB connectivity to your T51 for just $10 more with the USBCONV.
The Industrologic T51 is an incredibly versatile small microcontroller board. It contains everything needed to be a simple industrial controller, yet is simple and inexpensive enough to be a quick development and educational tool as well. Its RS-232 interface and on-board power supply means no additional circuitry to deal with, and its screw terminal connections for all of the signals and power means super easy to wire I/O.
Included with each T51 is development software including Extended or Enhanced Tiny Machine Basic pre-installed in the microcontroller, a wall block power supply, and a serial port cable to connect to your PC. (Things you must purchase separately with everyone else's single board computer.)
