Sensing and controlling the intensity of heat present in a substance or object is a fundamental function of nearly every electronic application. A temperature sensor is a device used to measure the amount of heat energy generated by an object or system. These devices are usually implemented as RTDs (resistance temperature detectors), thermocouples or thermistors. When selecting a temperature sensor, designers should consider the device to be measured, temperature range, accuracy, response time, stability, and sensitivity.
Today we’re launching support for one of the most-used PCB software flows – Mentor Graphics PADS & DXDesigner. Whether building satellites or medical devices, hardware designers spend days creating digital models for each component on their circuit boards, a painful and time-consuming process that hinders product development.
With today’s launch, Mentor PADS & DX Designer customers will gain access to our extensive component library containing millions of symbols, footprints, and 3D models, further enhancing the vast resources available for Mentor PCB design software. As of today, our popular 24-hour part request service InstaPart will also support PADS & DXDesigner.
In these free webinars, our product manager Mike Tang will show how you can save hours on PCB design with SnapEDA.
- How to download symbols & footprints
- How to create a private bill of materials (BOM) and batch export the libraries to your preferred design tool
- How to request parts with InstaPart, our popular 24 hour symbol & footprint request service
- Tips & tricks, and much more!
Looking forward to seeing you all there!
Whether you’re building a wearable device, or an industrial system, chances are you’ll be integrating an accelerometer. Accelerometers are electromechanical devices that measure acceleration across one, or multiple, axes. Some common uses are to detect position, velocity, vibration, and to determine orientation (for example, to orient the display in your smartphone or tablet).
The most important factors to consider when selecting an accelerometer are output type (analog or digital), number of axes, output range, sensitivity, dynamic range, bandwidth, amplitude stability, and mass.
Hi Suresh. Which tools do you use for circuit board design? Why?
Suresh: At my first start-up, we began by using Eagle Lite and KiCAD, because well…let’s be honest, they were free and we had no money. That doesn’t imply that they are bad. In fact, anyone getting into hardware design should use those two in lieu of the higher priced software.
Ever wonder which Bluetooth processors and modules are most designed-in to products? We took a look at the most designed-in Bluetooth components based on our download data at SnapEDA, which provides free symbols & footprints for millions of electronic components.
Note: This data is gathered based on the most downloaded parts on SnapEDA over the past few years. If a part isn’t yet available, then it may be missing from this list. For example, one notable omission here is the ESP8266 which is one of the most searched terms in our search engine. We’ll be updating this list periodically to account for any such cases!
Here is the countdown of the top 10 Bluetooth components on SnapEDA!
#10 – NRF1822-QFAA-R Nordic Semiconductor
Multiprotocol Bluetooth 4.0 Low Energy/2.4 Ghz Rf Soc
Average price across distributors at time of publish: $3.81 USD
#9 – RN42-I/R2 by Microchip
Bluetooth 2.1 class 2 surface mount module with built in antenna
Average price across distributors at time of publish: $16.71 USD
When selecting a Bluetooth solution for your designs, you might compare a processor and a module and think “well the Bluetooth processor is cheaper, so let’s go with that.” But the decision isn’t always so clear cut.
We had the opportunity to interview Sam De Marco, a sales engineer at Laird Technologies, to get his opinion on the factors designers should consider when selecting a bluetooth solution. Over the past 5 years, Sam has consulted dozens of customers on how to best integrate Bluetooth into their products and systems.
Hi Sam. What is the difference between a bluetooth module and a bluetooth processor?
Sam: From an engineering standpoint a module can be viewed as being like a miniature Bluetooth “daughter board” which can be designed using any of the several Bluetooth processors that are on the market today. A module essentially incorporates all of the components required to make the Bluetooth radio work and a module manufacturer will also carry out the necessary antenna design required to make the radio communicate reliably and correctly.
In addition, probably one of the biggest differentiators (and advantage) of using a Bluetooth module over a processor is certification. Most modules on the market today have undergone certification in order to operate in compliance with regulatory bodies such as the FCC, IC, and CE.

Good news for anyone on our Professional or Premium plans: unused InstaPart credits now rollover on quarterly and annual subscriptions!
InstaPart is our popular on-demand model request service that allows PCB designers & teams to get any symbol & footprint within 24 hours. InstaPart, along with several other features, is available with our paid plans, or can be purchased standalone.
Here’s how the new rollovers work: for those on the quarterly plan, you’ll now be able to request up to 15 parts with your plan within a 90 day period. For those on the Annual plan, you’ll be able to request up to 60 parts in a 365 day period.
If you need extra parts on top of that, or you request very sporadically and don’t want to sign up for a plan, there are InstaPart credits that never expire. Pricing for InstaPart credits is available here.
Again, all parts created with InstaPart are created & verified to IPC-7351 standards. After we create them, they’re made available to the entire hardware community to download for free on SnapEDA!
You can now convert your Eagle libraries to KiCad, Altium, OrCad (and other formats) on SnapEDA.
When Autodesk moved Eagle to a subscription model last month, many of our users began asking how they could translate their libraries.
We are big fans of Eagle and the new changes they’re making, and are confident that the subscription model will bring much-needed features to the software. But we also understand that it is (for many) a showstopper. Hopefully this free tool is helpful to those for whom this is the case.
Try the tool for yourself here, or watch the video below to see it in action!
