Stepper Motor Control

4-wire, 2-phase stepper motors can be controlled via digital outputs SQR1,2,3,4 . Since these outputs can only drive currents up to 20mA reliably, users must use push-pull drivers such as the L293B

Micro stepper motors shown below consume low amounts of

Wireless Nodes : Battery powered intelligent subunits

Wireless Subunits are battery powered devices with unique communication addresses. They are capable of relaying sensor data, and also include various I/O capabilities.

The 2.4GHz transceiver, and small form factor make it an ideal replacement for interfacing various sensors to

Linear Optical Sensing Array

The SEELablet can be interfaced with a 3648 pixel linear Optical array (TCD1304) from Toshiba. Its large pixel size , and configurable integration times up to 1 second enable data acquisition under very low light conditions
