Reference design small batch - Lala, Nora, Sophie, Sana & Kaylee (Audio, Sensors, RS-485 & IR TX/RX)

I’m having 10 each of Lala, Nora, Sophie, Sana & Kaylee printed, and if all of the parts are available they will be for sale in 2-3 weeks. If you are seriously interested, please email with the boards that you are interested in, and I’ll put you on the list.

I don’t have prices determined yet, but they will be as reasonable as possible, with the understanding that since this is a small batch, they will be likely be built by hand. As soon as I have the BOM and prices determined, I will post it here. The boards will only be available assembled, and not as kits.

For those of you who aren’t familiar with the available reference designs, Electric Imp has a number of really cool designs that are ready to be fabricated and built. Take a look at them if you are interested. Building them yourself is an incredible learning experience, and I highly recommend it if you are interested. I would be happy to relay my experience if anyone has questions about it.

Is it the Kaylee as per the reference design or with the additional AND gate?

This round will be Kaylee exactly as it is in the reference design. I haven’t been able to finish the RS485 shield for P3V3 yet.

Sorry for reviving an old thread, but I’m interested to buy an audio reference design with Imp. Lala board like would be ideal but I it doesn’t seem to be available anymore.

Anyone knows if it’s still on sale somewhere (hopefully with updated Imp003 or later as 002 is already EOL)? Or does anyone know an audio reference board similar to Lala that I can buy?


Well that’s perfect timing… we are working on an imp004m audio reference design right now. It’s sort-of like Lala except it uses a DFSDM digital mic and dual PWM for audio out (as the 004m has no DAC). Can run battery powered, and also has some hidden features that we’re revealing for the 004m shortly enabled.

Is a mic what you want for audio input?

Hi Hugo, yes we will need an analog mic for audio input, but other than that it looks like imp004m audio reference design would work perfectly for us. I imagine we’d need to get DFSDM to analog converter or some sort to get the board to work with analog mic?

Also when is this board be available?


We do use an analog -> DFSDM setup in our system tests for this feature, we may be able to share the details of that. Is there a specific reason you need to use an analog mic vs a digital one in this application?

First board has been tested and issues fixed, so design files for the second rev should be able to be emailed in a week or so I guess. I don’t believe we plan to offer this one on the store as it’s quite specialist, though.
