Build GNS530 for simulation MSFS2020 and MobiFlight

GNS530 - Simulation GPS - for Cessna 172 - DIY

Build your own GPS GNS530 for simulation cockpit.
Format for 6.25" stack
Electronics are design with EasyEDA.
3D parts are design with SolidWorks.
Parts printed with ANET A8 and CURA 15.04.6
PCB are sold by JLCPCB, you can use directly Gerber files --> JLCPCB
Only electronics, you can choose the microcontroller of your choice, the base design have addtionnal card for Mega2560R3. For mine i use Mega2560R3 and Mobiflight on MSFS2020--> MOBIFLIGHT
For others controllers you need to design the support for the card, or add wires to link them.

The Screen use for this project --> Aliexpress

3D Printing

Materials

- HEAD : 0.2mm and 0.6mm
- PLA BLACK and PLA WHITE

CURA configuration

With CURA you need plugin PauseAtZ, i modified the plugin to add 2 pauses (printing buttons by example) download and install it--> Here

SUPPORT for controller

Support for Mega2560 pro mini
