Power Supply
Power is supplied to the module through a 2mm barrel connector at location PWR or through
connector J1. Power may also be sourced off-module through connector J1. The PWR_SEL
jumper determines the source of input power.
PWR
The PWR barrel connector accepts 2.0 – 2.1 mm barrel plug and allows the module to be
powered from a transformer plugged into a standard wall outlet. Input voltage should be limited
to b4VDC and +12VDC. Input voltage of +9VDC @ 200 mA is typical.
Connector J1
Power may be supplied to the module through the pins J1-1 and J1-2. Use of this option
requires a regulated voltage input limited to +3.3VDC (+/- 5%). This input is connected directly
to the module power and ground planes. Care should be exercised not to over-drive this input.
This connection may also be used to power external modules attached to connector J1. The
PWR_SEL option header determines how power is routed to the module.
