Document default is TSIP for GPS
The following is a catalog of active components. Designators italicized still need positive identification; bold have been positively identified. Markings listed where known to help in identification. List additional markings when they differ.
'''U1''' - GPS - [https://www.trimble.com/embeddedsystems/copernicus2.aspx Trimble 63530-50] - 12-channel GPS, 2x serial ports, 2.7-3.3VDC, SBAS, flash almanac/ephemeris/location storage. (The -50 variant is probably a custom variant, and exact capabilities are unknown.) This chip defaults to TSIP on the 38400 baud port, which is a binary protocol.
''U2 - (Marked G4/905)''
