Developing a universal module

I realized as I was going that there is no reason to directly control the paen/lnaen pins in most cases. These could be tied to the output GPIO and we could program them via SPI on the modules themselves.

I haven't actually tested it on a real module, but assuming thatit works, here's an initial draft of the circuit diagram:

It is strange, I have not seen the last two posts before I sent my message. After this came the fifth page with two additional messages.

Where we can get CYRF6936 module? I cann't find any in sale.

Th thread got derailed in the end, but there are some sources in here:

Here's a rough layout for the board. I want to mock it up and see if it'll fit in my transmitters. I placed the cyrf module on the back, and stack the nrf module op top of the a7105 module. It will add thickness but reduce x/y. I need to do some measurements to see if I can actually fit it inside any Tx though.

I'm going to try to fit a few different module layouts on the board, especially an AWA24S CYRF module which is quite a lot smaller than the CYRF equivalent.

what is the module running horizontally on the top?

I mean this one:



I guess you are right as it has a 4x2 pin header and by process of elimination can't be anything else. I haven't seen that variant of the nrf24l01 I think though.

Edit: I see. It is the standard nrf24l01 but with the antenna port removed

Here is my breadboarded design. It'll fit in a devo7e and devo8, and will go into the module cover of the X9D if you remove the pins (In the final design I'll see if I can avoid them so it can be used without removing them. It has a CC2500, A7105, and NRF24L01+(No PA, but I believe the PA version should fit just fine). The CYRF module would attach to the back (I'm going to try using the AWA24S instead of the Devo module due to it being smaller, and roughly the same price shipped)






Note that this is still untested as I don't have the ATTiny chips I plan to use with it yet. I'll finish designing the board with a similar layout to this (I want to try to squeeze 1/4" off the board to get it under 2", though I'm not sure that is possible), and get a few printed. It looks like BatchPCB closed up shop, which is too bad because I had really good luck with them in the past. Has anyone used OSHPark? They look like they're likely to have the fastest shipping speed. Not as cheap as Seeed and the like, but it looks like you get a really high quality board.

If you are trying to squeeze in a tight space, beware the remainders of breakaway tabs randomly placed along your outline. You can clean that up of course, but it's fiberglass

I never had that with my BatchPCB boards. I'll just have to see how it goes I guess.

Edit: I had problems uploading my images. they are fixed now.

Board ordered from OSH Park. I'm using a smt mounting technique for the A7105 and CC2500 modules. I'm not sure the pads are right, and I'm not 100% sure of the clearance, but at $8.50 shipped, it is easier to ship it off and see if it works.

I should have my ATTiny chips mid-week, so I'll throw together some software to control them in the mean time.
