The Pmod OC1 is an open collector BJT module using MMBT3904 transistors. Users can then drive high current devices (up to 200 mA) by providing logic signals from the host board.

Features:

• Four 100mA (200mA max) MMBT3904 transistors
• Four output clamp diodes
• 40V voltage threshold
• Small PCB size for flexible designs 1.0“ × 0.8” (2.54 cm × 2.0 cm)
• 6-pin Pmod connector with GPIO interface
• Follows Digilent Pmod Interface Specification Type 1
