5 Power Supply
Two power supply sources are available to start the Development Kit Q26:
These power supplies are protected by a transient voltage suppressor.
Each of these power supplies is used for both the Wireless CPU and the peripherals
on the Development Kit Q26.
It is possible to disconnect the power supply for the Wireless CPU ("VBATT",
measurable via the TP153) and for the peripherals ("VBAT", measurable via the
TP157).
Current measurement is possible between the VBATT and VBAT via J103 (refer to
section 20).
5.1
"VBAT" indicator is a green LED. It indicates the external power supply presence. In
other words, peripherals and Wireless CPU are respectively powered via VBAT and
VBATT.
Hence, the Development Kit Q26 is operational.
