New board designed based on my original GPS UTC clock

https://www.pcbway.com/project/shareproject/GPS_set_clock.html

This version has all the pins from the Nano avaliable and a small brerakout section for other projects.

This PCB board was designed to interface a NEO-7M GPS and Arduino Nano to a 1602 LCD Display in a compact form that will fit inside a Transparent Acrylic LCD Shell for 1602 LCD display.

The time and date are set by a GPS and display the UTC time on a 1602 display, can also be programed to send data via USB.

Code for the Arduino Nano can easily be changed to display local time and other data available from the GPS, like the location or grid square, a quick search on the internet will find lots of programing options and suitable code, just change the LCD and GPS pins in the code to suit the board.

The 1602 display is connected to the Arduino Nano using pins RS-D2, E-D3, D4-D4, D5-D5, D6-D6, D7-D7 and the GPS is connected using RX to D9 and TX to D8, The LCD 16 pin header socket, is fitted to the bottom of the board

I have added the option of a pin for the PPS out from the GPS, or jumper JP1 can be soldered to connect Nano pin D13

It should be possible to interface other GPS modules to this board but the interface pins and module size would have to match or be connected via wires and the GPS mounted somewhere else.

This project can be powered by a USB cable connection to the Arduino Nano or via an optional 7 to 20VDC external supply.

It would also be possible to use a 5V external supply and bypass the regulator circuit, just a few jumpers in the right place.

RV1 is used to change the contrast on the LCD.

RV2 is used to change the brightness of the display and can be less that 10kΩ, was convenient to use 2 the same, a fixed resistor about 220Ω can be used instead but it’s nice to be able to adjust the brightness of the backlight LED.

A 2004 LCD display could be used or/and a different enclosure.

It is possible to use this board for other projects, I will be using this board for a Morse code oscillator and decoder by using the GPS socket to connect a key and amplifier board to a speaker,

Thanks for looking
