will it do anything?
I bought a roomba on Ebay that supposedly had had the motherboard removed. I got it, put in my good battery, and it works great.
The seller had sold another identical-looking, supposedly working, one the same day. Wondering if they had accidentally gotten switched, I contacted the other buyer. She said theirs ran about two minutes, "made some noise", and quit. Am I correct that without a motherboard it wouldn't have even done that much? |

| The term motherboard is ambigius here. If your Roomba did not have the Printed Circuit Board then the complete system would not work at all. No LEDs would work, no buttons would work, nothing. This is due to the fact that everything electrically is connected to the motherboard (PCB). The motherboard has the MCU (Microprocesser Unit) and program that tells the Roomba what to do and when to do it. |
