SparkFun Photo Interrupter Breakout Board - GP1A57HRJ00F Infrared Networking - Wireless Products It’s not what project you

It’s not what project you have in mind that may use a rocket launch switch… The question is what project will you come up with once you have one in hand

The rated open circuit voltage is 350mV (900nm

It’s the unit we like to use as RTC backup and SRAM backup for GPS units

the FT232RL will enumerate as a virtual COM port

SparkFun Photo Interrupter Breakout Board - GP1A57HRJ00F Infrared Networking - Wireless Products It’s not what project youA simple breakout PCB for the GP1A57HR photo interrupter. This PCB has three connections for PWR, GND, and Signal. When the gate is clear, SIG will be high (>4. 9V). When the gate is blocked by a finger, writing utensil, food pellet, or anything else SIG will go low (<0. 4V). Assembled picture is for reference only, board comes bare; photo interrupter and the 220? (330?, works as well) current limiting resistor are listed below. Documents: Schematic
