Zitron sorry for the late response.. You can send/sell the pcbs that you reserved for me to other guys...
I'll probably make my own diy single layer boards and use an arduino nano..I'll make the connections per flytrons schematic so that I won't need to tinker too much with the code..I'll make the nano removable so that I could remove it from the board when uploading new sketches (since 5V would kill the rfm22b)..

I would take yours if there would be a possibility to easily port openlrs code...but its a bit too complicated for me..
Hope you continue with your nice project and post code...Hope then when you write your code for lrs you'll still have some pcbs to sell :D.

Hi Zitron,

I'm still interested, I'll PM you over on FPVUK.

Regds,

Nigel.

I can solder SMD and get all the components needed; I have lots of open source arduino projects done but... I don't write arduino code... if you do not mind sending me the actual code, as well as any updates, I think I'll have no problems. If you do not mind that your project is shared, I think it might bring some progress in the project through some friends. But as I said before ... I do not write code...
Zitron What do you think? It is worth I join the project? 


You/anyone can use my design files and code for whatever purpose. Just make sure you know what you are getting into, it's not a fully featured product, and will likely to have many problems.

I think that is probably the best thing for you to do. Trying to port someone else's code will be very time consuming, especially if you have limited experience! Also bear in mind that by the time you bought your nano, all the components and boards I think you might as well buy direct from Flytron! It would be really nice if they released a DIY OLRS kit.

Here are some pictures of the new Rev 2 board. It's 50x43mm compared to 50x50 Rev 1.

If you are building one I suggest soldering the SMD components first, and use a bigger cap in C7 (I said 100uF in BOM, probably should be 470uF) especially if you use a lot of servos.

Looks great Zitron, a piece of art!

Using those cheap chinese nano clones, i think i can get bellow the price of one Melih's receiver and I also save for a ftdi, since they have an onboard ftdi (I would remove the nano from the headers when uploading)..

I'd be interested in buying a booster pcb from you (same layout as Melih for the same chip), maybe if you could design it in a way that the resistors, caps, diodes,  etc would be of a bigger size, for easier diy work...Do you manufacture these pcbs by yourself?
