Wireless transmitter & receiver modules Symbol and Footprint repo for KiCad for 433mhz (also includes eval boards for development use)

KiCad-LPD_Wireless_Modules

Wireless transmitter & receiver modules Symbol and Footprint repo for KiCad (also includes eval boards for development use)

Development status: Alpha (Expect sloppy commits, force pushes and big changes in the library. Library is highly WIP and expected to break every few commits. Any feedback is welcome.)

What is this repo for?

This repository contains symbols and footprints for various cheap LPD (low power device) radio modules for transmitting and receiving of signals on the 433/868/915 MHz frequency. These modules are meant for use in other systems via soldering onboard, hence the need for a library that provides definitions of these modules for use in programs like KiCad. By making the footprints and symbols available, it makes it easier for others to develop and prototype boards using these modules.

How to use

1. Clone this repository or download and unpack the zip file either from master or releases.
2. Add the symbol and footprint library from KiCad -> Preferences -> Manage Symbol libraries... and KiCad -> Preferences -> Manage Footprint libraries...
3. Check if new LPD_Wireless_Modules category appears.

kicad-lpd_wireless_modules's Issues

Make proper Courtyards

https://klc.kicad.org/footprint/f5/f5.3/

A fully enclosed Component courtyard must be drawn on the F.CrtYd layer, with the following parameters:

• Courtyard uses 0.05mm line width
• All courtyard line elements are placed on a 0.01mm grid
• If the component requires a courtyard on the back of the PCB, a corresponding courtyard must be provided on the B.CrtYd layer.
• Where the courtyard depends on the dimensions of the physical part body, clearance is calculated from the nominal part dimensions.

Courtyard clearance should adhere to the following requirements:

• Unless otherwise specified, clearance is 0.25mm
• Components smaller than 0603 should have a clearance of 0.15mm
• Connectors should have a clearance of 0.5mm, in addition to the clearance required for mating of connector
• Canned capacitors should have a clearance of 0.5mm
• Crystals should have a clearance of 0.5mm
• BGA devices should have a clearance of 1.0mm

Decide if footprints should strictly follow KLC or not
