ELECTRICAL SPECIFICATIONS
The input power to the SBC is provided by a power supply (battery or wall adapter) or an USB
source, for battery charging purposes. All input power sources enter the PM670, which are then
distributed via LDOs and switching power supplies. Since these input sources are susceptible to
external factors, the following table shows the absolute maximum ratings in which the PM670
can be exposed to without experiencing functional failure.
4.1
Absolute Maximum Ratings
The Open-Q™ 605 SBC can be powered by either a single cell Li-on battery, 5V-15V DC Power
via the DC Jack, or through the Expansion connector J3600. Either of these sources enter the
PM670 power management chip.

Recommended Operating Conditions
According to component datasheet values, the operating conditions outline the parameters in
which a user can control the behaviour of the SBC. If used within the following conditions, the
SBC will meet performance specifications (provided the absolute maximum ratings have never
been exceeded).
