Title: Interest in 1284P boards?
Post by: CrossRoads on Aug 10, 2013, 08:29 am
I've had enough inquires that I've finally put together a Mouser/Dipmicro price for 25 of my 1284/FTDI kits.
These would be unassembled kits with the board and all components less the onboard USB/Serial adapter (Mikroe-483) or a 7.5V/9V/12V wallwart.
Pretty much as pictured here, with male pins for the top left 2x3 header (I2C/A4-A5 select), generally smaller Rs & Cs, 4 different color 3mm LEDs (Power, L, Rx, Tx) and 4 female jumpers (shorter than pictured), for the power select, reset enable, and I2C connections to A4/A5 if desired.

Board + components + flat rate mailing to US addresses: $27. International, I have to get a quote from the USPS, probably another $5 more. They've been fiddling with prices recently, might be a little less.

Mikroe-483 with 15-pin socket could be added for $11
7.5V or 9V or 12V wallwart could be added for $4
Spare Atmega1284P-PUs, $5.75 each.
Assembly of the board could be added for, I don't know, have to see long it takes me to assemble one.

If interested, PM me, or ask questions here. Payment will be via paypal.
Schematic, link to mighty1284 core files, and updated pins_arduino.h for Bobuino board type are here.

Well I've already bought 2 of your blank PCB for this board and have one populated and working well. However to encourage the use of this great board I would like to buy one kit version. Let me know when they are available to ship and what your paypal ID is.

Thanks

Thanks Lefty. Paypal will be to cardinalflyer @ comcast dot net.
Let's see what interest is like, or if this whole idea falls apart and I go back to just offering bare boards.

When I was looking for a more stable 1284P prototyping platform, there were only two that sparked my interest:

1. The Atmel MEGA-1284P Xplained  http://store.atmel.com/PartDetail.aspx?q=p:10500272#tc:description
2. and your board.

Didn't go with the XPLD because of the fluff.

I really like your setup, but I use JTAG for debugging and programming.

There are a few more options out there but all in all, for the 1284, choices are pretty limited.

I ended up making my own (I was tired of wires and thru hole components going everywhere).  Have all the parts, the PCBs will arrive in 3 days.  Here is a rendered pic if curious. I don't have a cool name (or any) for it.

If you make a through hole version in the future with JTAG broken out, I will definitely be interested in purchasing one or two.  I like the idea of being able to swap out the chip if needed.

OK, CR, count me in for two.

interesting layout drobe011. You're a little more hard core on tools than most with the JTAG investment.

Runaway Pancake, just interest & qty is good for now. That's at least 4.

@CrossRoads add me in for two as well.

Title: Re: Interest in 1284P boards?
Post by: CrossRoads on Aug 11, 2013, 01:13 am
Okay, that's 6. 4 or 5 more and I'll place the order and take a chance on the balance.

So should I place an order at this time?

I'm in for one board and one Mikroe-483.

9 + 1 controller. I have a fencing meeting in an hour, if the wife doesn't make me too busy I'll order parts when I get back.

I suggest moving this thread to Products & Services and waiting a few more days.  I suspect you'll pick up a few more.
Title: Re: Interest in 1284P boards?
Post by: CrossRoads on Aug 12, 2013, 03:35 am
I will be ordering some extra 1284's also for those that want a 2nd or 3rd microcontroller, $5.75 each.
Added to the list of costs in the original post.

note to all:

I built out one of these a week ago, the board is very good quality.  I'm using mine with a lab supply and did not build out the power supply.  Build time about 60 minutes if you pull all the parts ahead of time and have a proper heat, small tip soldering iron.

I'm using Sparkfun's FTDI module, auto-reset works correctly.  A knock-off Hong Kong version also worked, but the Sparkfun is dual-voltage via jumper clip, nicer.


You will not be disappointed.

Ok folks, please send your order requests with payment via paypal to cardinalflyer @ comcast dot net.
Be specific on what you want:
# of kits
# of extra 1284's if desired
wallwart  voltage if desired
MIKROE-483 if desired

I got home later than planned after a contentious meeting, so the ordering will happen tonight.
I still plan to order for 25 kits, but will not be ordering wallwarts & MIKROE-483s unless they are asked for.

[EDIT] I'll hold off on ordering until Wednesday night (east coast US time) to allow a little time for folks to respond, I have no particular reason to rush.

Count me in for 2 unassembled kits (no wall wart) plus 2 spare controller chips. Canada.

Thanks!


If it is not too late change this to 2 unassembled kits (no wall wart) plus 5  spare controller chips

Post by: CrossRoads on Aug 12, 2013, 09:10 pm
Can do. $27 + (5 x $5.75) = $55.75.

$27 X 2 + (5 X $5.75) + $5(Canada) + $2(1 beer for you) = $89.75 US dollars,  Correct?

Post by: CrossRoads on Aug 12, 2013, 09:52 pm
Yes, thanks for the correction. For multiple kits, its $27 for 1st and $22 for additional, I can stuff multiple kits into 1 box. So $84.75 with the beer tip 8)
Title: Re: Interest in 1284P boards?
Post by: hiduino on Aug 12, 2013, 11:16 pm
@CrossRoads can I also get just order the parts, less the PCB?  I still have two of the PCBs I ordered previously.

Title: Re: Interest in 1284P boards?
Post by: CrossRoads on Aug 13, 2013, 02:55 am
Sure. $27 - $4.50 = $22.50
1 set?

Still accepting orders - paypal to cardinalflyer @ comcast dot net
Please indicate if you want something besides the basic board & kit.

Gang,
I received parts from Mouser, realized I ordered two 5V regulators,  instead of 5 and 3.3V.
Mouser doesn't have 3.3 in pinout needed, going to order from digiikey instead.
Do you see  any benefit of  one of these over  the other?
Both are sourced from 5V, with 5V-Gnd-3.3V on the pins left to right and tab at Gnd.

http://www.digikey.com/product-detail/en/MCP1825S-3302E%2FDB/MCP1825S-3302E%2FDB-ND/1636103

Looks like my 4th LED color, blue, went out of stock before they shipped.  Rats!

TC1262...
- Uses a bit less power so it's a slightly better choice for battery power.

MCP1825...
- Seems to have a slightly lower dropout voltage.
- Has "short circuit protection".  The other one has "over current protection".  From the description, it sounds like "short circuit protection" is more robust than "over current protection". 


Looks like either one would be a good choice.  I don't have a preference.

Just marketing type word choice, short circuit protection is a subset of over current protection.

All righty! 25 kits prepared, first 8 going out tomorrow, 15 or 16 are left (I think I am short 1 socket for the last one).
We assembled one to make sure my installation instructions are good. Found out order is a little important for 1 cap, other than that it went smooth. If I do this again, I will order different 0.1uF caps.
Bootloaded and installed Blink, board works as expected.
Here's pics with a couple of shields, one shows mating with the ICSP header, the other shows the cap that needs to be watched during assembly, put the headers and the cap in place before soldering any of the three and they fit fine.

Schematic, Layout, and Assembly Directions are on the website

robtillaart,
$22 for the kit (no USB adapter), $12 for international shipping.

Got mine two days ago. It's been too warm here to solder up in my din/man cave but I will get around to it.

Some kits are still available - and now Henning Karlsen has updated his UTFT library to work on Bobuino boards as well.

http://www.henningkarlsen.com/electronics/
Library link: http://www.henningkarlsen.com/electronics/library.php?id=51
Great demo video at the bottom.

Henning says "There are a whole heap of displays that are supported. I have attached a list of the displays I have tested with UTFT (this list is also included in the downloadable file). I have not had the time to test every single one with the Bobuino, but if one works they all usually work. I have tested with 8-bit and 16-bit communication so I believe all the displays on the list should work. The larger displays from Coldtears Electronics (5" and 7") requires additional power so they will not work with a standard Arduino Uno shield."

Just a note regarding the 1284P...

If you have not worked with this chip, you are missing a real thrill.  The 8x additional SRAM along warrants your attention.  Having Ports "A" and "C" fully available as an 8-bit parallel bank is also quiet beneficial.

CrossRoads' board is a fine board, too, and I have 3.  Highly recommended.
