Great work,I would love to start development on the STM32F4. I had a seminar a few weeks ago about this STM32f4 and got the discoveryboard with it. I was impressed by the presentations about the performance and had the same idea that you…"
The problem with the max7456 based OSDs is the powerdisipation of this chip. But on rembizi OSD is also a linear voltage regulator which is heating up the board even more. What I did is making a small rembizi compatible board without the…"
"Farooq, there is not much to port, it is based on the apm+oilpan I did a the port for the sd746. I have to do the airspeed sensor and extra servo outputs and the three open drain outputs. But I start first with testing on the basic functions. Maybe…"
"Mike, I will not going to produce these board in high quantities maybe I will make a few boards if there is interest or sell some bare pcbs so people can assemble them self, but due to the fine pitch and qfn packages it is not an easy job to do. I…"
"Andre, due to my job it's easy to get all the necessary components, especially I'm in close contact and do direct business with Atmel. But you can buy all the components from Farnell, Digikey and for the gyro you can buy them from a German…"
"farooq, that is exactly what i had in mint. I have a Octo with mikrokopter electronics that I want to replace with this autopilot in the future. So having two extra servo outputs is always useful...but first is the axn floater that will get this…"
"Patrick, thanks for the compliment, indeed there is no USB converter on my boards, i did this on purpose. Now i can use this uart for ohter things like for instance osd. And THE other big reasion is that i didn't want to have stuff on my boards that…"
Hi guys, Here I want to show you my new autopilot hardware which I worked on the past weeks.The layout and the connections of the boards are chosen for my own convenience.So airspeed sensor, receiver input, GPS, LEDs and I2C connections are at the…
Hi Guys, I have been busy with testing the SD746, or lets say get it to output some data so the AMP can work with it.The SD746 combines a 3D accelerometer with a 3D gyroscope and signal conditioning circuitry in a tiny QFN package. It provides…
@Johann, range is highly depending on antenna system and regulations you want to meet, but more than 5Km LOS must be possible.
@abey, that's why I like this statement of the Radiocarft datasheet :"The use of RF…"
Here is a preview of my long range wireless modem.It's based on a Radiocrafts 868Mhz module (RC1180HP) with 450mW RF output power and good receiver sensitivity.I'm going to use this for modem telemetry and antenna tracking, one in groundstation and…
