Hi guys! I'm giving you a preview of an upcoming product from the DIY Drones store, the MinimOSD, a minimal 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 header.
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.
Spec lists are the best, so here's one!
- 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
- Solder jumper for PAL video option
- Exposed test points for HSYNC and LOS
- Dimensions: 0.7"W x 1.7"L (2.4" w/ pins as shown) x 0.3"H
The production version won't be green, and we're not too fond of blue anymore, so expect something different on future products ;)
(And yes, I know I missed a decoupling cap on the board in the photo. Sorry Chris!)
Expected release date is within 2-3 weeks, price is TBD. Watch this space! UPDATE: Price will be $89.99 USD.

Neat design, good price (Remizbi price is low because he gets free engineering samples to build his OSD!)
Q: Why is there an NTSC/PAL solder pad? the max chip can detect and tell the firmware what signal is currently getting in from the camera, and switch automatically. And default can be a startup option. Having to un-solder and re-solder when changing cameras would be impractical and many ground stations / video goggles etc automatically switch.
Also, is there any hardware support for audio? for example adding vario tones? If the circuit is there, this is just one digital and a spare timer..
thanks im waiting on xbee pro also was hoping to ship all at same time
If i were you i would order two or three, so that if one is lost, you will be sure to get one. :=)
More seriously i didn't saw it on the store for preordering. So you'll have to check that each day to be sure to get the first one...
Being a DiyDrones client is a very hard task, when such nice products are released...
can we pre order yet to be shure we get one?
Great ! For sure i will offer that to my frame.
Niiice! Want one.
@tangtl: I didn't know that. Thanks.
Is the current code extracting that info? If so, can be seen on the Mission Planner?
@I.S. : I think 1 analog input is enough for main controller receiver RSSI , XBee RSSI can be extracted from MAVlink, but the OSD should 2 RSSI displays .
And how about this one( Arduino OSD):

Really cheap. Heck, Remzibi is not much more and that includes GPS and Prolific cable. And there is already lots of work done to integrate it into APM. But, I am not familiar with APM or MavLink so I don't know what value that adds.
@Marc: That's the point
