It’s an excellent idea as it will continue to provide the OSD overlay even if the video is lost. This board features two independent power and ground sections to isolate the OSD’s analog stage: a +5V section for the ATmega and the OSD’s digital stage, powered through the FTDI cable or other +5V source and a regulated +5V section for the OSD’s analog stage, powered through the video in/out header and capable of handling Minim OSD V1. The MinimOSD is usually mounted in the plane or quad, but rcgroups user ‘007trains’ had the idea to mount in on ground side ( see his post here). If one of these links give good results let me know and I’ll remove the other ones. It's main components are an ATmega328P 8 bit microcontroller with an Arduino bootloader, and a MAX7456 monochrome on-screen display. Mini OSD v1.1 - compatible with Arduino available in the category: OLD PRODUCTS. It's tailored for use with ArduPilot Mega and the MAVlink protocol, and designed to be as small as possible. Unfortunately I didn’t try it yet, but here are the posts where he provides the modified firmware and explanations.Īnother similar modification made by burtgree : Minim OSD v1.1 (36844) This is a mini Arduino based on-screen display board. You’ll have to share the same serial port between ULRS and minimOSD, and it has to work at 19200 bauds.Ī minimOSD version recompiled to work at 19200 bauds was made by rcgroups user mcfly. I don't have a great understanding of MWOSD, but it's not a flexible as BF OSD is. The desire would be to have the ease of OSD element/display configuration and the BF OSD elements available on MWOSD. You can use one serial port for ULRS, and the other one for minimOSD, and use appropriate baudrate for each : I thought that the Atmel proc would be a bottleneck, but didn't think of the slow UART speed to the external OSD. Product page on Hobbyking for version 1.1.One picture is worth a thousand words, here’s an example from the MinimOSD wiki :įor more information about MiniOSD please check the following links : MinimOSD is a an open-source OSD (on screen display) for FPV, which is able to directly decode mavlink data and display it as an overlay over the real-time flight video.
