Pytrack + GPy. Where to connect sensors?

  • Hi everyone,

    This might be a very basic question. How should i connect my two ultrasonic sensors to the Pytrack/GPy? Should i use the external IO headers of Pytrack or connect directly to the pins of GPy?

    Thank you

  • @fedonman Depends on the sensors really. What bus (i2C, SPI, etc) or other port you need. Other factors are the power supply required and any other such factors. My practice is to extend the bus/es from the sockets Expansion/Pytrack board to a protoboard, so I am able to connect more than one device, power supply, level shifters, pull up/down resistors, capacitors etc if required. Makes it easier to work on and follows on with making a custom PCB later on..
