Figure 77 shows the robot and a Raspberry Pi 2 mounted on three 25 mm long circuit board spacers. The holes for mounting are already present in the robot
board. The connection between the Raspberry Pi and the robot board was made using jumpwire connectors. The cables of the jumpers were placed under the
Raspberry Pi to get a clean wiring.

It's possible that your SBC reacts very sensitively to voltage fluctuations and safe operation is not possible via the battery, which also supplies the leg
servos.
In this case we recommend to supply the SBC via a small separate power bank. In practice, a battery capacity with a Powerbank of 2000 - 3000 mAh
is sufficient to supply the SBC until the Hexapod battery is empty. Sometimes it is also sufficient to support the power supply directly at the SBC with
a large capacitor of 2200 μF (or more).
The reason for the unstable operation might come from a battery that is too small with high internal resistance, or from servos with very high current
consumption or large current peaks.
