A300 Power and Signal Converter

Overview

The A300 is a logic-level shifter and voltage converter. It provides two level-shifting channels: the first converting 5 V to 3.3 V, and the second converting 3.3 V to 5 V. Additionally, the A300 provides a regulated 3.3 V power output.

The A300 is commonly used when connecting the pulse-per-second (PPS) output of a GPS16X-HVS to a CR800-series, CR1000, or CR3000 datalogger. In 2014, Garmin changed the PPS output of the GPS16X-HVS from 5 V to 3 V. Units with a serial number 1A4189318 or greater have a PPS output of 0 to 3 V. For those units, an A300 is needed to connect the PPS output to a CR800-series, CR1000, or CR3000 datalogger. Those dataloggers require the PPS line to have a voltage of 3.8 V or greater.

Compatibility

The A300 is used when connecting the pulse-per-second (PPS) output of a GPS16X-HVS or GPS16X-HVS-PW to a CR800-series, CR1000, or CR3000 datalogger. It is not needed with a CR6 datalogger.
