About the BPV4 Collar 2nd board

BPV4 Collar 2nd board is an open source PCB design by rees3901, published on GitHub. It is a 2-layer board measuring 45 × 25 mm, with 26 components from 18 distinct parts.

Other key parts include the SKY65723-11 and GM02SP. By type, the board carries 12 resistors, 5 connectors, 5 capacitors, 2 ICs, 1 transformer and 1 diode.

It belongs with the rf & radio designs in this gallery.

From the project

version 4 of my on-going cat tracker project. this differs in structure in that both the TX collar and Rx homehub will be in the same repo to ensure intercompatability

KiCad projects and their supporting component models are grouped by product.

For GM02SP, GNSS/LTE antenna, and modem power decisions, start with the Walter/GM02SP source guide. Its Walter board specifications must be checked against the bare GM02SP and the production collar schematic before being used as PCB requirements.
