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.

I use the SparkFun's breakout board for MAX7456 + an Arduino Pro Mini. I'm not 100% sure but I think you only have to configure the SPI ports in Spi.h:
...
#define SCK_PIN 13
#define MISO_PIN 12
#define MOSI_PIN 11
#define SS_PIN 10
...
Has anyone integrated SparkFun's breakout board for MAX7456 OSD in the APM2 using the ATMEGA2650 SPI?ISP port? If so can you direct me to some details or help.
Remzibi has other focus which is support it's own set of sensors. But it's possible, of course... mainly because is almost the same hardware.
Though Remzibi is a lot mature, MinimOSD is heading to fill that gap. Isn't that simple due we have now two MAVLink version running (0.9 and 1.0) and also ArduPlane and ACM are not totally synchronized in terms of attending to all the data we want to show on screen. It`s all in constant development... we are trying to do our best to keep it going to achieve the same maturity as Remzibi.
Just a note? the announcement of MinimOSD was done some days ago here.
Cheers.

Waiting too.. can't believe Remzibi did not update firmware to support MAVtalk.
Me waiting for it too ! Would add some great functionality to the setup
Any update? Alternatively, can the same functionality run on the Remzibi OSD?
@Dror: The first version of the firmware is up and running. It's being tested.
I believe that now it's just a matter of few days.
3DRobotics guys are working hard on the first batch of APM2.0. So, we'll know it more precisely on next week.
Any news on this OSD? When will it be available?
MinimOSD.
