Flexible peripheral modules for all your designs
Pmod devices are Digilent’s line of small I/O interface boards that offer an ideal way to extend the capabilities of programmable logic and embedded control boards. They allow sensitive signal conditioning circuits and high-power drive circuits to be placed where they are most effective - near sensors and actuators.
Pmod modules communicate with system boards using 6, 8, or 12-pin connectors that can carry multiple digital control signals, including SPI and other serial protocols. Pmod modules allow for more effective designs by routing analog signals and power supplies only where they are needed, and away from digital controller boards.
Overview Pmod Tof
The Pmod ToF (Time of Flight) is a sensor that enables optical distance sensing at low power. The on-chip digital signal processor on the ISL29501 calculates the time it takes for light emitted by the ToF to travel to the target and back, which is proportional to the distance to the target. The Pmod ToF can measure distances of up to five meters.
It operates using the principle of Square Wave Modulated Indirect Time of Flight (SWM-ITOF) in the frequency domain and obtains distance measurements from the phase shift. The sensing is done by an external emitter (LED) and detector (Photodiode).
