APM MinimOSD Rev. 1.1 Kit
MinimOSD, an Arduino-based on-screen display board.
It's tailored for use with ArduPilot Mega and the MAVlink protocol, and designed to be as compact as possible. It's main components are an ATmega328P 8 bit microcontroller with an Arduino bootloader, and a MAX7456 monochrome on-screen display. Programming is done through an FTDI-compatible 6-pin cable.
It 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 up to +12V input. Solder jumpers are available to combine the two power and ground sections if desired.
Starting on 4/30/2012, all boards are version 1.1, which reflects a change in the voltage regulator to deal with excessive heating issues.
