I have a raspberry pi stack (containing 4 raspberry pis). I have a single GPS with serial and I2C output. I want the supply the GPS information to all the 4 raspberry pis simultaneously. Is it possible to short the RX of all 4 raspberry pis and attach the TX of GPS module to them? Is there any other way I can supply GPS information form a single GPS to multiple raspberry pi's simultaneously?
EDIT: I have shorted out the RX pins of Raspberry Pi zero W (GIOP15/ PIN10) and connected them to the TX of the GPS. The Pi's also have a common ground
