3.1 Recommended operating conditions
Table 3.
Board operating conditions
Typical operation is based on a 5 V
/
2 A power supply via USB
.
Each USB port allows a max current of 2 A
.
If you need
additional power
,
you can connect power to both USB ports
.
For more details

logic thresholds
Each I
/
O pin supports a max current of 16 mA
.
However
,
default drive strengths may be lower and vary between pins
.

3.3 Power consumption
The power consumed by the board varies based on a variety of system behaviors
,
including the extent to which the Edge
TPU is being used
.
Typical scenarios that we
'
ve tested show average power peaks around 3 W
.
Beware that
,
depending on the type of ML model you
'
re using
,
the Edge TPU can cause signi
fi
cant spikes in current draw
.
For more details about the Edge TPU power consumption
,
see the Coral Accelerator Module datasheet
