Looking for detail info of the motor driver board of an Robotino2

[Hoverpal]

Hello !

I have a problem with a Robotino2 motor driver board.

By accident, the board lost one of the SMD condensators on the PCB during a crash. I cannot find any specs of this SMD capacitor, it is marked C_81 on the PCB..

If somebody of the forum has an Robotino2 with the V2.1 board, could you please take a look at your board and tell me what it reads / what color it has of even better what value it has (if one of you has a schematic) ?

Looking from the back of the Robotino in the direction the cam faces, it is a tiny capacitor sitting on the motor board directly in the neighborhood of the square IC..

Thanks for your help !

Could you please provide a photo of the board and mark the position where the capacitor is missing?

I found C1_81 in the schematic of the V2.1 board. It is 100nF and for smoothing the input to IC11 (VN340). If this what you are talking about just ignore the missing capacitor. I can not imagine that you see any difference to the IO connectors digital outputs 0,1,2,3 with or without this capacitor.
