The SparkFun Artemis is FCC Certified!

via SparkFun: Commerce Blog

We did it, everyone! SparkFun’s Artemis Module has earned approval from the Federal Communications Commission (FCC) and Industry Canada (IC), making it the first open-source, US-manufactured, FCC/IC-certified BLE module on the market. With this certification, the SparkFun Artemis Module enables product designers to use the same module from prototype to production, and significantly increases accessibility of low-power machine learning for any design!

Fully certified and ready for any product!

SparkFun Artemis Module - Low Power Machine Learning BLE Cortex-M4F

SparkFun Artemis Module - Low Power Machine Learning BLE Cortex-M4F

WRL-15484
$8.95

In terms of technology, the SparkFun Artemis Module is on the leading edge of low-power machine learning - it can be powered from a single coin-cell battery. It is a Cortex-M4F with BLE 5.0 running up to 96MHz, with power needs as low as 6uA per MHz (less than 5mW) and a footprint of only 10mm by 15mm. The module enables the integration of TensorFlow into any design, runs machine learning models locally, and can be programmed and used with the Ambiq Apollo SDK or Arduino.

Three new Artemis RedBoards!

To make getting started with Artemis even easier, we've put it on three different boards to get you up and running: the RedBoard Artemis, RedBoard Artemis Nano and RedBoard Artemis ATP (All the Pins). Each of these boards has been equipped with Qwiic connectors, enabling immediate access to the extensive SparkFun Qwiic ecosystem to easily integrate more than 70 sensors and accessory boards. That means no soldering is needed and they are all daisy-chainable.

The SparkFun Artemis Module and the three Artemis RedBoards are available today. To find out more about each board, you can go to their respective product pages or the Artemis home page linked below. We'll go into a little more information on Artemis this Friday, along with a special deal that we are sensing you might be interested in!

Distributor Notice: The SparkFun Artemis Module is unavailable for distributor purchase until October 14, 2019. For more information on pre-ordering, please fill out this form: http://www.sparkfun.com/preorder_artemis.

New SIK Project Videos

via SparkFun: Commerce Blog

A few weeks ago, with the release of the new SparkFun Inventor's Kit - v4.1, we also made the decision to make our popular guidebook for the kit available in as many formats as possible. This includes the a physical guidebook found in the SIK v4.1 (as well as a standalone version), an online guide found on our learn site, an online flip book (coming soon), and now a series of videos covering each of the five project topics, three of which are now available for your viewing pleasure!

Project 1: Light

Project 2: Sound

Project 3: Motion

Project 4: Display will be out next week, and Project 5: Robot will release the week after, so make sure to check back!


Have you picked up your SparkFun Inventor's Kit v4.1? Do you own a SparkFun Inventor's Kit v4.0 and want to upgrade without paying for a full new kit? Maybe you are an educator that needs to supply your class with a full set of SIKs for your students. Check out the options below for the SIK that best suits you!

Keynote speeches from Scratch Conference Europe 2019

via Raspberry Pi

This weekend, the Raspberry Pi Foundation hosted Scratch Conference Europe 2019 at Churchill College in Cambridge, UK.

Framing the busy weekend’s schedule were presentations from:

  • Massachusetts Institute of Technology (MIT) Media Lab’s Mitchel Resnick, co-inventor of Scratch himself
  • Science presenter Neil Monterio
  • Raspberry Pi favourite, the fire-loving Fran Scott

Since not everyone was able to travel to Cambridge to attend the conference, we wanted to make sure you’re not missing out, so we filmed their presentations, for you to watch at your leisure.

For the full Scratch Conference experience, we suggest gathering together a group of like-minded people to watch the videos and discuss your thoughts. Alternatively, use #ScratchEurope on Twitter to join in the conversation with the conference attendees online.

Enjoy!

App note: Thermal mass flow sensors for gas and liquid applications

via Dangerous Prototypes

White paper from Integrated Device Technology on the emergence of MEMS thermal mass flow sensors. Link here (PDF)

Flow meters represent the instrumentation of flow sensors and are used to measure the amount of flow that passes through them. There are in principal five different flow meter types: velocity flow, positive displacement flow, differential pressure flow, open channel flow, and mass flow. Mass flow meters are one of the dominant types in the market due to their faster response and better accuracy than other flow meters. They can also be effectively miniaturized and manufactured on silicon wafers. The emergence of MEMS has already revolutionized the consumer electronics market for motion, pressure, and other sensors, and similar micro-machining processes are now being adapted to fabricate flow sensors. Flow sensing applications are typically high-mix and low-to-medium volume compared, for example, to motion sensors that have become ubiquitous in hundreds of millions of smartphones. This paper will focus on the emergence of thermally-based MEMS mass flow sensors and how they match up with existing and more traditional flow sensor technologies.

App note: Ferrite bead demystified

via Dangerous Prototypes

an_analog_AN1368

App note from Analog Devices hinting for proper selection of ferrite bead for you applications. Link here (PDF)

An effective method for filtering high frequency power supply noise and cleanly sharing similar supply rails is the use of ferrite beads. A ferrite bead is a passive device that filters high frequency noise energy over a broad frequency range. It becomes resistive over its intended frequency range and dissipates the noise energy in the form of heat. The ferrite bead is connected in series with the power supply rail and is often combined with capacitors to ground on either side of the bead. This forms a low-pass filter network, further reducing the high frequency power supply noise.

BP

Every Friday we give away some extra PCBs via Facebook. This post was announced on Facebook, and on Monday we’ll send coupon codes to two random commenters. The coupon code usually go to Facebook ‘Other’ Messages Folder . More PCBs via Twitter on Tuesday and the blog every Sunday. Don’t forget there’s free PCBs three times every week:

Some stuff:

  • Yes, we’ll mail it anywhere in the world!
  • We’ll contact you via Facebook with a coupon code for the PCB drawer.
  • Limit one PCB per address per month, please.
  • Like everything else on this site, PCBs are offered without warranty.

We try to stagger free PCB posts so every time zone has a chance to participate, but the best way to see it first is to subscribe to the RSS feed, follow us on Twitter, or like us on Facebook.
