7.11 Jumpers J55 and J56 – Input Power Path
Jumpers J55 and J56 connect the Evaluation Carrier battery charging subsystem to the rest of the Evaluation Carrier.
Refer to Figure 2 Input Power Path Block Diagram for an illustration. There are two different ways to power the ULP-
COM Evaluation Carrier:
»
Bench Power Connector J29 (with jumpers J55 and J56 open).
»
Battery Charger / Battery Power Path - J28, J23, J24, J25 (with jumpers J55 and J56 closed; connector J29
open and not used).
Caution!
These paths are mutually exclusive – you must use one or the other.
Caution!
The Bench Supply connection, through J29, is convenient and easy to use. The two J29 power feeds may be
wired together and can be sourced from a single 5V supply. If using the Bench Supply power path, jumpers J55 and
J56 must be open.
