POWER
The DEMO9RS08KB12 may be powered from the integrated USB-BDM or from an on-board
voltage regulator and external power connector. The desired power source is selected using
the PWR_SEL option header.
For application development and debug, the board may be powered from the integrated USB
BDM. As noted above, total current consumption from this source is limited to 300 mA. A
2.0mm, center-positive, barrel connector (VIN) and on-board regulator supports stand-alone
operation and higher power requirements.
Power may also be applied to connector J1 or the board may be configured to supply power
from connector J1 to external circuitry.
POWER SELECT
Power may be applied to the board through the integrated BDM, through the 2.0mm barrel
connector and on-board regulator, or through connector J1. Power selection is achieved using
2 selection headers: the PWR_SEL option header and the VX_EN option header.
PWR_SEL
The PWR_SEL option header allows the user to select power input either from either an
external power source connected to the VIN connector or from the integrated USB-BDM.
Figure 3 below details the PWR_SEL header connections.
