Just over 2 years ago the Raspberry Pi foundation launched the original Compute Module (CM1), which was based around the same BCM2835 processor of the original Raspberry Pi. The Raspberry Pi Foundation launched this board aimed at the industrial market, where companies were using the Raspberry Pi for commercial purposes...

As shown in previous sections, active filtering and CMRR can reliably reduce circuit noise in the device’s band-limited range, including DM and CM EMI up into the MHz range. However, exposure to RFI noise above the intended operating frequency range may cause non-linear behavior in the device...

The creation of cost-efficient and compact industrial slave devices that can connect to any Real-Time Ethernet network is now simplified through the combination of the STMicroelectronics STM32 ecosystem with the multi-protocol flexibility of Hilscher’s netX control ICs...

STMicroelectronics has begun volume production of ultra-low-power STM32L45x microcontrollers, supported by a development ecosystem based on the easy-to-use and affordable STM32Cube platform. The STM32L451, STM32L452, and STM32L462 lines integrate a Digital Filter for Sigma-Delta Modulators, enabling advanced audio capabilities such as noise cancellation or sound localization on an inexpensive microcontroller...

The newest family of PIC32 microcontrollers is now available from Microchip Technology Inc. The PIC32MK family features four highly integrated MCUs for precision dual Motor Control applications and eight MCUs packed with serial communication modules for General Purpose  applications...

The new high-connectivity STM32L4 IoT Discovery kit (B-L475E-IOT01A) from STMicroelectronics gives unrivalled flexibility for developers building IoT  nodes by supporting multiple low-power wireless standards and Wi-Fi , while integrating a complete collection of motion, gesture, and environmental sensors, unavailable on other kits in the market...

The SAM R30 System in Package, a single-chip RF microcontroller, is now available from Microchip Technology. The SAM R30 SiP incorporates an ultra-low power microcontroller with an 802.15.4 sub-GHz radio, providing multi-year battery life in a compact 5 mm package. The SAM R30 SiP delivers design flexibility and proven reliability all in a small package, making it ideally suited for connected home, smart city and industrial applications...

As in a previous Design Idea, this design uses an LED as a transducer to measure the ambient-light level and to provide illumination. This Design Idea uses the same principle as its predecessor but consists of only one LED, two resistors, one IC, and one 0.1-µF bypass capacitor...

Some time ago I was poking in my box of old components. I was searching something else, but I stopped when a few of nixies came up into my hand. Once upon a time (a long, long time ago) I have mined them from an old calculator...

Analog Devices announced an ultra low power microcontroller unit that addresses the rapidly growing need for embedding advanced algorithms while consuming the lowest system power at Internet of Things edge nodes. The ADuCM4050 MCU includes an ARM® Cortex®-M4 core with floating-point unit, expanded SRAM...
