I have three separate devices that all need access to a data serial port on the pi. My devices are an accelerometer, a GPS unit, and a GMS cell service chip. I've found tutorials on how to attach these to the pi and manipulate each individually, but my experiment really needs all three attached at once, and it is my understanding that the pi only has one serial data input.
Is there a solution to attach all three devices to my pi? I'm using a raspberry pi 2.
