Specifications: Weight: 3.3g Dimensions: 34 x 17 x 4mm Working Voltage: 7.2~12v
However, if your cam and Tx are on a different power source (if you've a dedicated battery for tx and cam for example), you MUST connect the video battery's ground to the battery1 connector's ground.
Great! I power my FPV stuff off of my flight battery, and the cam has an internal battery. I usually connect video and ground straight to the VTX, so it should not be an issue. Is there a way to change the position of the information on your screen? Thanks -RC2211
The most simple answer should be "NO" as there's nothing provided by HK to do so.
However, like all HK's products, this item run an ATMEL Mega 8 (or something close). That means it's highly probable that there's a hack somewhere on the web (try rcgroups forum, hack e-osd or something).
Great OSD !
Sometimes difficult to understand the "how to", so the french legend of the tutorial (AKA Porco777) made a great tutorial on how to connect it, for french user, there is the video.

Doh, it has 2 sensing connections . Thought one was just to power the unit. My bad :)
Just got mine. Works fine. It is worth the price. Pretty simple to monitor FPV pack battery or motor battery (if under 3S). There are some interesting projects to do RSSI monitor (check rcgroups). You have to to make a Y connection between camera wire and tx wire to the OSD (video input) i.e camera signal and tx signal going into video input on the OSD. Gnd can come directly from pack.
