Minim OSD v1.1

Minim OSD v1.1
Minim OSD v1.1

This is a mini Arduino based on-screen display board. It's tailored for use with ArduPilot Mega and the MAVlink protocol, and designed to be as small 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.


• ATmega328P with Arduino bootloader
• MAX7456 monochrome on-screen display
• FTDI cable compatible pinout
• Standard 6-pin ISP header
• Two independent power sections with an LED indicator on each
• Solder jumpers for combining the power sections
• +5V 500mA regulator for up to +12V supply input (5-12v range)
• Solder jumper for PAL video option
• Exposed test points for HSYNC and LOS

Voltage: 5-12v
Dimensions: 50 x 18 x 10mm
Weight 4g

Hello, i got this OSD working with the preinstalled firmware 2.1 but when i update to a version higher than 2.1 (i tried 2.1.5, 2.2, 2.3 and 2.4), i dont get flightdata anymore. The video OSD panels etc. still work but i dont get real data from my HK-Pilot Mega 2.7. When i downgrade to v.2.1 it works perfect again. Some ideas? Furthermore i don get the combination HK-Pilot Mega 2.7 together with MinimOSD v.1.1 (FW 2.1) and HKPilot Transceiver Telemetry Radio Set V2 working. It works when i only connect one of the components MinimOSD or HKPilotTelemetry but when i connect both to the HK-Pilot Mega 2.7 with the Y-cable both doesnt work. Hope that anybody could help? Thx

This is an awesome OSD for the money. I recommend flashing with the kvOSD firmware for a really powerful, informative OSD.

Can a 4 pin connector be connected to the serial port 1 on the multiwii pro since the gps is on serial port 2 and this work through serial port 1? Can serial ports just be soldered on with pin connectors like here?: ***********ebay****/itm/370879588366

Dock have to do anything to the firmware to make this compatible with a naze32?

You don't have to but I recommend flashing this with kvOSD firmware.

Will this communicate directly with a MultiWii? I want to access the Multiwii sensors on screen by connecting to my OSD port on the Multiwii Pro (which need to have pins added).

It could, yes, google multiwii minimosd and you'll find a page with explanations and required hardware.

Works at 5V/PAL (soldered the jumpers) without any problems. Very nice product! Paired with HK MegaPirate AIOP board v2.0 plus HK UBLOX plus HK Bluetooth. Nice combo, Hobbyking!

excellent product, got it working with multiwii easier enough after flshing rush-osd and setting it up via rush gui. would be nice if you had jumpeers for your external monitor leads rather than having to solder onto the main chips legs but that it a problem with the initial design not hobbykings copy of that. i run mine off 5v with the soldered pads.

No heating problems if used with a 2S 7.4 pack. A bit hot, but within acceptable limits.

Good job HK.
