Remzibi OSD
This page is related to the alternative hardware I made for the Poor Man’s OSD also known as Remzibi OSD.

Here is the result – revision A of my hardware:
The hardware was designed after the original schematic from Remzibi with some minor modifications. Mainly some more pins for ADC inputs, the bottom side is almost flat to add a heat sink and the ISP connector has been changed to STK500 style.
I added diodes on all battery inputs to protect the cicuit from wrong polarity. Also a LM2940CS-5 is used to generated the 5V supply voltage due to the lower voltage drop compared to the 78M05 and therefore lower heat dissipation.
The following two images showing the pin out of each PCB side.
PCB size remains the same like the original one and is 46mmx25mmx7mm with a weight of 9g.
You can download all files of my hardware design here:
Included are the schematic, layout, Gerber, BOM, License and original Remzibi files.
Of course my hardware is full compatible to the original Remzibi firmware and to Pauls aka happykillmore configuration tool:

The actual hardware and all further versions are releases under the TAPR Open Hardware License.
