The M5211DEMO is designed to be powered from the USB_BDM during application development. A
2.0 mm barrel connector and a two-position, screw-type, terminal block (BATT) has been applied to
support stand-alone operation. Additionally, the board may be powered through connector J1. The board
may also be configured to supply power through connector J1 to external circuitry. An OFF/ON switch
allows you to quickly and easily turn the board on and off.
When using the integrated USB-BDM, the board draws power from the USB bus. Excessive current drain
will violate the USB specification causing the USB bus to disconnect forcing a POR. Total current
consumption of the board and connected circuitry, therefore, must be limited to less than 500 mA.
The installed barrel connector accepts a center-positive, 2.1 mm barrel plug. The terminal block accepts
wire sizes ranging from 28 ga to 16 ga. Voltage input must be in the range between +5 V and +20 V. At
no time should input voltage exceed +20 V as damage to the board may result. The terminal block input
is connected directly to the upper voltage rail. Input protection is not applied on this voltage input.
Exercise caution when using the terminal block to input power to the board.
Voltage supplied through connector J1 is also connected directly to the board voltage rails. No protection
is applied on this input and you must exercise caution when powering the board from connector J1.

Note: This header is not installed in default configuration.
Violating the USB specification will cause the USB bus to disconnect. This
will force a hard reset on the target.
Input protection is not applied to the J1 or BATT power inputs. Excessive
input voltage or current will damage the board.
