README
README.mdHardware and software for an opencpn-based chartplotter The kardware has been designed with kicad 4.0.x The chartplotter is built around a A20-based single-board computer from Olimex (https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2/) and a 15" TFT full HD display also from Olimex (https://www.olimex.com/Products/OLinuXino/LCD/LCD-OLinuXino-15.6FHD)
The hardware consist of 4 boards
- a breakout board for the Lime2, also providing power supplies, an audio amplifier, RS422 and CAN interfaces, and a I2C connection to a PIC18 for power management and TOD clock.
- a board holding buttons
- a board holding a GPS module
- a board for connections to other electronic equipements (VHF, sensors, ...) via a single flat cable.

Questions
How big is the Marine gps PCB?
It measures 160 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Marine gps use?
115 parts, built around the PIC18F25K22-I/SS, MAX3488EPA+, MCP2562-H/P and TDA8541T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Marine gps KiCad files?
From the mbouyer/marine_chartplotter repository on GitHub, at the commit this page was made from: the board is hardware/marine_gps.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Marine gps design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
