3Connector Applications
3.1. Tape-B USB Connector
Both Type-B USB connectors can supply power for the EVB. The power supply current of EVB cannot be
lower than 2A.
EG25 USB AT Port is mainly used for the account configuration of RTK.
Enhanced COM Port is mainly used to configure LC29D module and firmware upgrade.
Standard COM Port is mainly used for LC29D module NMEA output.
EG25 USB Connector USB TO UART Connector
