At this stage we continue working on the L8 development
overcoming the obstacles that we have found in our way, and thus, we
can guarantee you that we're getting closer to ending the L8
Now that everything is on the right track and direction, we want
to share with you the project status and some of the problems that we
Let’s begin with the microcontroller. This one has been the most
serious unexpected problem that arose and the main reason for the
production process delay.
The microcontroller is one of the main parts of the L8. It is the main
chip on the board and controls everything that happens inside the L8.
This chip controls the LED matrix, reads the sensors, stores the
L8ties and sends and receives the information through the Bluetooth
module and the USB port.
The microcontroller we chose was an ARM Cortex-M3 developed by Texas
Instruments. We chose this microcontroller because it was launched
just a few months earlier, and therefore it was the latest technology.
In spite of this, the manufacturer changed the product status of this
chip to NRND, which means Not Recommended for New Designs.
This situation made us to shift to a different microcontroller, which
led to a L8 hardware and software redesign.
Here, you can see an extract of the manufacturer published announcement:
“Texas Instruments will be announcing the change in status of the
Stellaris LM3S devices to Not Recommended for New Designs (NRND). This
is a natural step in TI’s efforts to focus its new product development
and manufacturing efforts on TI’s differentiated 65nm technology. TI
remains committed to providing customers the industry’s best Cortex-M
There is no change to the production status of the LM3S devices. TI
will continue to support all the devices from the LM3S family as long
as there is sufficient demand on the market, and in the accordance
with the standard TI obsolescence policy. Customers will continue to
receive application support as well as hardware and software support.”
Nevertheless, we already have a new microcontroller (also an ARM
Cortex-M3 latest generation), and the new hardware design for it.
As for the production, this L8 first badge will be produced in Spain.
This allows us direct control and assures optimum quality throughout
the entire process.
Here you can find all of the L8 production lines current status:
• Hardware. Matrix 8x8 LEDs: Our customized matrix are already ordered
and in manufacturing process
• Hardware. Components supply: The majority of the components are
already on their way to the factory and we hope to have them all
during January to begin the final manufacturing.
• Hardware. Electronics assembly. The factory is waiting for the last
components to begin production.
• Enclosure. The Injection mold is already in production and we will
soon receive the first injected plastic final samples.
Software: We are finalizing the sdk development, backend and apps, and
we expect to deliver the first SDK version for developers in early
Soon we will have the first pre-series and samples that will be used
to evaluate the production processes quality and the devices
themselves. And of course we will post pictures so you can follow the
process with us.
We only ask a little more patience, because we are very close to make
the L8 shine.
Thank you again for your support and understanding.
