Four receiver diversity board for 5.8Ghz video. Features onboard regulator, buzzer, oled and more. Should fit in a compact form factor.
I need to get the software working properly. I've tried to leave the source available where possible, though I haven't documented much of this as its a personal project.
Some enclosure concepts have been drawn up.
The board has been made, and a basic level of validation done to show that everything works hardware wise.
The schematics and gerbers are all in this repo if anyone wants to borrow ideas for similar designs. There are other boards out there like the RX5800-Pro project and similar, but we use the TX5813 modules on this board due to native SPI support (no need to mod the 5800 internal resistors).
The board is a simple 2-layer, 1oz design that fits inside a 80x80mm footprint. It should cost less than $40 to produce if you buy parts from Aliexpress/Banggood/Chinese sellers.
