New 1284P-powered board suggestions

Do you have an idea for a device that you think Freetronics should create? Discuss your ideas here! Sometimes we may even give you a sneak peek at secret projects we have in the pipeline, or ask for feedback on designs before they go into production.

I'd hate to see another dip (unless you used a quad pack).
I'd prefer to see a clean mid range board for battery use:
. No ethernet - if you need that you most likely need the mega 256.
. No sd card (Maybe - I'm still between 6 & ½ dozen - it would make a nice battery logger)
. rtc yes - if you can keep the battery low profile that would be nice.
. An I2C bus (+ 5v & earth) connection area
. +3v / +5v option jumper
. vin / usb option jumper

How about a surface mount compatible prototype area?

Keep up the good work guys! :idea:

Thanks
Any thoughts on which SMT package type?

Maybe you could also sell a standalone chip like you do with the atmega328 (with the bootloader) sometimes a uno chip is too small but a whole board isn't needed.

Latest post on my progress with the Goldilocks Analogue.

New PCBs have been ordered, and hopefully some new prototypes for testing within a month or two.

Very impressive Phil. I had missed this up to now. Will this ultimately be a kickstarter, or even a freetronics product?

Geoff,

Yes I'll put this up on Pozible once I've got it right. Its easiest to limited production that way via Freetronics. Most manufacturing won't do runs of less than 100. And I am relying on Jon's toaster oven (and hours of his time) to get the prototypes done.

I'm working on the software now. Ladyada libraries will work out of box, with an adjustment to the Chip Select, but I like to play around.

Phillip

Well, I've now got all the parts for a new Goldilocks Analogue prototype, and the PCB ready for the new design. I'm just awaiting the uSD Card cage, before the next assembly and testing run.

A bit of a misunderstanding at Seeed with the PCB cost a few months. I was distractedly waiting for them to ship. Seeed was awaiting my comment on a Gerber issue before proceeding. Easy to burn time like that, with both sides awaiting progress from the other.

Interesting that there is now another Analogue Shield available from Digilent. Based on a Stanford University teaching requirement. There is code on Github. It is great that there is now a real analogue option available for the Arduino platform.

And starting a design review post for the next (possibly final) version of the Goldilocks Analogue.

I've finished the new layout, and updated the post here.

The board is more tightly packed than ever, but it now has even better prototyping and pin-out capability.

I've also added 2x SPI RAM layouts, to enable up to 2Mbit of additional SRAM (FRAM, NVRAM, EEROM). This space could be used to hold 30 seconds of sound clips, for example. Or to act as large buffers for data sampling.

Also added an I2C pinout compatible with Raspberry Pi pins 1 through 5. This is to allow easy I2C connections, but most importantly to allow RaspPi RTC modules using DS3231 to be plugged for accurate time keeping.

Hopefully, I'll be able to construct the new PCBs in late January.
