A few pictures of the recycling of my vacuum cleaner robot:

The "power" board

This board uses an Atmega microontroller. It is in charge of all I/Os (including motor control). The board is fitted with two full H-bridges (one per motor). It communicates with the man board (a raspberry Pi 2) via a CAN network.

A small TDA 2030 audio amplifier

Note that I have slightly modified the schema given in the datasheet: I have added a 220nf capacitor and a 150K ohm (in series) on the feedback (pin 4 to pin 2).
