NMEA0183Adapter-7.1
About the NMEA0183Adapter-7.1 PCB
NMEA0183Adapter-7.1 is an open source PCB design by peterantypas, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 52 × 42 mm, with 39 components from 34 distinct parts.
Other key parts include the AP3211KTR-G1, L76-M33, ADuM121N, DMN63D8LDW-7 and SE8533X2-HF. By type, the board carries 11 capacitors, 8 resistors, 6 ICs, 4 LEDs, 3 connectors and 2 transistors.
From the project
MAIANA™ is the first Open Source AIS transponder. It proudly raises an extra long middle finger to the marine electronics industry, government overregulation and everything else that gets in the way of innovation in this space.
This directory contains Eagle CAD files as well as schematic PDFs and Gerber exports for board fabrication.
The board stackup is good enough for either OSH Park 4-layer, or JLCPCB 4-layer with controlled impedance (JLC2313).
Revision 11.5.2 does away with the (hard to source) regulator from ST and replaces it with a Zener + NPN combination that delivers about 8.5V to the PA under load.
