Hi there,
My new devo 10 from TM actually arrived today. I have no plan for 3 or 4 in 1 yet. I have ordered a couple of cheap CC2500 modules, but they are still somewhere on the slow boat. I have standalone A7105, NRF24L01 modules in my 7e. The CC2500 would complete the set in the new devo 10 so that it would be XK110 ready and be able to talk to my WNCPX and X303V fleet. I still like my 7e, there is no urgency to fully equip my new devo 10 right away. I'll wait.
My JJRC H11D also arrived yesterday. It was not too impressive. Probably I'll spend some time to capture the camera control for it this weekend. I have posted the CC2500 RadiaLink TX capture, I haven't heard anybody working on it yet. To look at it myself, I guess the H11D camera extension may be a better start. Initialization and binding would be the most complicated part. I can capture the Lidi L6F too, but I wonder if anybody would be interested in looking at an unknown RF chip. At one time GB sold the L6F TX at around $10. We may harvest the unknown RF module from a fresh TX.
Have fun.

I'm trying to get away without MCU, with couple of logic chips
Also, I would not rely on Amazon too much - when they realize the module does not have FCC certification they can stop it. I would ask Banggood to provide clearer identification and revised product with fixed bugs. I asked the producer of the modules - he said the new ones should be available in 2-3 weeks from the end of April, that is now. I'd give it couple more weeks to tune up pipeline.
I will ask him about availability and issues again.

I feel the situation around these two modules is a bit messy 
First of all, we were told several times that the issue in 3-in-1 module had been fixed. But we haven't seen that module yet. There are already two or three batch of 3-in-1 sold so far. But they are all the same module that has the same PA/LNA control problem.
As for 4-in-1 module, we have seen at least two or three different versions (or just different adapters with the same core module?). One of them is apparently for non-deviation - i.e. Universal module. Another one looks like a promising almost-drop-in mod for devo 10. But we haven't seen its formal release, let alone the review/test.

Folks might be interested in this.
Here is victzh's 4:1 adapter with 4MB flash along with the 4:1 board installed plugged into my DevoF7. You may see a small wire soldered on the board. This is to make it easier to test the AT9 using a single board, and is not necessary for functionality with either the AT9 or devo radios...except for a minor issue with the LDO (which is my own fault) I have found no defects in the board.

It isn't 100% operational yet,because I haven't finished all the coding, but it seems to work as expected.
The board is entirely plug and play (no need for any soldering to the Tx) on everything but a Devo7e.. On a Devo12, and F* (and I guess 7e though less useful) the board can replace the onboard FLASH with a much larger 4MB variant. This should allow the 12S to not need a separate filesystem for the media directory, and would allow installing all modules on the F7/F4. On all radios, it would allow direct access via USB without dealing with the 'devo.fs' filesystem.
Does anyone have a contact for whoever is sourcing boards to bangood/taobo? I think this is probably an ideal board to be 'the' board for Deviation radios. It should be inexpensive to manufacture/purchase (though the cost of the 4:1 remains). If we can't find someone to produce them fully assembled, I may be willing to sell a batch of them partially assembled (everything but adding in the 4:1 board, which isn't too hard), but it is still a lot cheaper to have them shipped directly from China to the users (since China shipping is much cheaper than anything the USPS can do). As I've said previously, I am not willing to be involved in selling the RF portion of the boards. Also, be aware, this is victzh's project, and any distribution of the board is entirely up to him.
