@ WW - On the E100, is low-power really even a thing? With the E28 or a custom design using a MM2 I can certainly see why you would want low-power mode for battery operation, but the E100 with it's thirsty LCD screen makes the 10mA or so of the 1455 chip negligable I would have thought....

@ Rob - Yes, a DIL socketed IC would be the best way forward with that. There MIGHT be room for that as an idea - I will look into it, then if you want the 1455 interface, you just plug in the 1455 DIL chip. If not, remove it.

I realise that to some extent I am opening myself up to design-by-committee again here with this thread, but so far I am happy with suggestions.

That is not a cue for members to start suggesting flux capacitors and time circuits.......

Do any of the members here have any major problems with that concept?


ESP-8266 users will be compromised.

On mine I use the CP-2102 header for a plug to connect the ESP-01 as I mentioned here....




I could live without that particular connector, but as long as I still had access to Tx & Rx before the 1455, as on Con6.

All my MM's including the E100's are connected by Wifi & I'd be totally lost without that functionality.





Having to take a laptop & USB to all of them for code changes would be a huge PITA.

at should still be available via some means.

Think this applies to all devices using the 1455; Direct Tx & Rx Needs to still be available.

Cheers

Phil.

OK folks, thanks.

And Phil - you make a very good point, and hammered home well with the photos.

I think what I will do, is leave the CP2102 header and CON6 there, but perhaps change the SOIC 1455 to a DIL version, so that if you want the USB serial connection and/or the ASCII ICSP feature, you plonk the DIL chip into a socket on the E100 board.

I think that would then cater to everyone. Those that DON'T want it cos they currently have arrangements such as Phil, but also those that DO want that extra feature. This also means just one version of the PCB.

So, that is how I am going to proceed.

- CP2102 footprint will stay.
- CON6 will stay.
- 1455 will change from SOIC to DIL and socket
- Silkscreen changes to LED's as suggested by WW
- Add uSD card socket as suggested by WW.

It was worthwhile posting this thread.

OK, DIL 1455 mod done. I just have to do the other suggestions.





Install the DIL 1455 in the socket if you want the USB console and/or ICSP programming ability, don't install the chip if you don't want that ability and would rather use the CP2102 or CON6. I think that best deals with every situation, yes?(rhetorical!)

So Con6 etc will all still work with the 1455 plugged in?

I'd see myself using Wifi on almost exclusive basis,
but would have the 1455 sitting in wait for ease of upgrade for firmware whenever it comes around.

No.

If you want the 1455 interface, you can't use the CP2102 footprint or CON6.

UPDATE:

OK, here we are with the new design.





- Optional socketed 1455 USB/ICSP interface chip with on-board ICSP for IT
- Silkscreen changes as per WW request(around LED's)
- uSD card socket added(SD #2), upper-left corner.
- CON10 removed.
- PIN_17 added to PIN_51 header as a spare I/O pin.

I will probably tweak a few more things, but this is essentially the new version of the board I plan to get made.

@G this looks great and should meet most people's needs. When they are done I think I will swap my current E100 for one of these and re purpose the current one. This will make things much neater

@Phil - is there a place where you describe in detail how you have gone about having all your MM accessible by using ESP-8266 modules? I have a number of MM doing data monitor and capture and keep thinking they are finished only to find a week later I need to make a s/w change. I am getting sick of removing them and opening the up.

I am using HC-12s to move the data around and am happy the way they are working. I was thinking of using another HC-12 on each unit to enable console access remotely but when I tested it out transfer of the s/w was quite slow for the more distant units. Your wifi connection looks more elegant and robust. I have no experience using the ESP8266 and don't want to bite off a big chew. I have raised this before and not yet come to terms with it.

@Grogster

Really nice layout.

What PCD Layout/Routing s/w are you using?

I don't quite get this, as I understand others are using either HC-05's or ESP-01's on E28's.

Isn't the circuit similar in most respects?

I know the Wireless device would probably be removed for the 1455 to work.

Rob mentions something about it in this thread, but not sure if it's relevant.
