"I already have a Sparkfun FTDI to serial converter  the ones I have has a TTL level module and one with an USB/FTDI chip not sure if you bought 2 if you can configure the 2 TTL serial modules to talk to each other or not"

"Just ordered one of these, Aren't you getting the usb-ftdi interference mentioned above? I was thinking of un soldering the usb converter and simply attaching a ftdi cable, would this work?"

"Depends on what you need I suppose I just like tinkering. I will give the 3DR radios a go in a boat see what happens in anger The Xbee based definitely worked at my skill level probably at a range of 300 meters"

"Good work Nick, Thanks for sharing.  So do you think it is not worth doing this for full fledged RC control with xbee/similar radio module?"

"After further experimentation  I confess the latency is awful unless you use it as a simplex connection Cheap though could use a 433Mhz and a 900Mhz together one for control and one for Telemetry In the end the Xbee works well with a 5:1…"

"Thanks for the tip I have not tried them long range will need to hack/wire into the PC end with the FTDI and eliminate it so I can use another ARduino for the  TX anyway. My first model with these modules is a boat in any case so not so…"

"Those HK radios are basically 3DR radios with an annoying mini-plug and a 433MHz ground module with integrated USB - which 3DR has abandoned for a reason - the FTDI chip creates RFI around the 433MHz band, leading to range problems."

"The plane above is using 2.4Ghz Xbee  These HK devices are not Xbee the 433Mhz and 900Mhz modules both seem interchangeable the air rate is variable depending on the conditions. The fact of the matter is it does work in practice I have used…"

"This is what I discovered Some things I have learned about Xbee from hands on experimentation. 1) Keep the packet size to < 100 bytes in either direction 2) Allow for 50% dead air on 20mS at 38,400 my TX packet is sent in…"

"Xbee based RC attempts were made years ago, the creator of OpenLRS was the last who convinced himself they are not a solution due to latency and buffering these devices does. Telemetry yes, RC no, or anything where you need better than 0.1 second…"

"I do too use it a lot at work. You can use VS 2010 C# on the Netduino/FEZ Panda with Micro CLR but its not real-time I tried to use Netduino a while back so now I use Arduino  for my projects. I will have the TX running on Arduino soon…"

Small FPV Setup 2.4Ghz

Posted on February 24, 2013 at 4:30am 3 Comments

200 mW TX on a 120mAh Lipo runs about 30 mins. Total weight with Lipoly 6.2 Grams, only 3.6 Grams with a 5V regulator so it runs of the main battery. The image is not great on a single Lipo cell. I will try it connected to a spare port on the RX see what the signal is like.…
