About the Gps development boards PCB

Gps development boards is an open source PCB design by leonardoward, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 107 × 88 mm, with 29 components from 13 distinct parts.

Other key parts include the ATGM332D-5N31 and M20050-1. By type, the board carries 17 connectors, 4 capacitors, 4 resistors, 2 ICs, 1 diode and 1 inductor.

It belongs with the rf & radio and dev boards & breakouts designs in this gallery.

From the project

Development Board designed with KiCad for the ANTENOVA M20050-1 and the ATGM332D-5N31

A KiCad breakout board for evaluating two GPS modules side by side — the ANTENOVA M20050-1 and the ATGM332D-5N31 — plus two footprints for 20 mm coin‑cell holders to keep the module's backup RAM / almanac powered for a warm start.

This is one of the breakout boards made for the EJA "Intelligent Popup Buoy" project (2021 Hackaday Dream Team). Each candidate part for the EJA M board was first tried on a small dedicated PCB. Both GPS modules speak plain NMEA over UART and are wired to identical header pinouts here, so the same ESP32 firmware runs against either one.…
