Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style), allowing the user to pick devices with the appropriate step-count per revolution, with or without a push switch. “The [pre-soldered] on-board microcontroller is programmed with ...

Having trawled though Arduino’s just-released Uno R4 literature, here are the Uno R4 WiFi and R4 Minima in a nutshell: Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V. USB connector changed to Type-C. 6 – 24Vin (barrel jack – higher than ...

Novocomms, the UK antenna design specialist, is expanding its operations in Birmingham following a successful “multi-million pound” funding round. Specifically, the company is set to hire additional engineers and salespeople, move to new offices and create 100 jobs by September 2025. Up to 30 of these roles are expected to be created in the next six months, it says. The ...

Swissbit, the Swiss industrial storage and security specialist, is introducing e.MMCs and SD memory cards with capacities ranging from 4 to 8GB. They are based on 3D-TLC-NAND and optimised for power failure protection, industrial reliability, and high endurance, says the company, which suggests IIoT and smart city applications. e.MMC EM-30 Taking the two products in turn, the Swissbit EM-30 (153 ...

Arduino is launching new versions of the Uno board powered by a Renesas 32bit microcontroller. The Uno R4 comes in two versions: the basic Uno R4 Minima and the Espressif-equipped Uno R4 WiFi. Described as a significant revision of its 8bit technology, the R4 will preserve the standard form factor, shield compatibility and 5V power supply of the well-established Uno ...

Bourns has announced a AEC-Q200 compliant, automotive grade semi-shielded power inductor series that operates across -40 to 150°C. SRN8040HA inductors are constructed using a “silicon-based coating that offers magnetic shielding”, according to the company. They “are designed to release lower magnetic field radiation compared to non-shielded inductors, and are a more cost-efficient alternative to fully shielded ferrite-based inductors”. The data ...

To help give robots a sense of touch, Bota Systems has created a six-axis sensor that can measure forces and torques on end-effectors. MiniOne Pro EtherCAT measures x, y and z force up to 50N with 35mN (21mN for z) noise-free resolution at 100Hz, and torque up to 1Nm with 0.4mNm (0.3mNm for z) resolution. To this, and internal inertial ...

Yokogowa has added HCDR (high close-in dynamic range) mode and SMSR (side mode suppression ratio) mode to its AQ6370 optical spectrum analyser. Found in AQ6370E, HCDR mode allows measurement of a single longitudinal mode laser with a high close-in dynamic range – CDR is a metric important when developing lasers and optical devices. SMSR mode is intended to halve SMSR ...

Toshiba has created a range of 36V-capable LDOs to work from USB-PD and 24V power rails. The first three devices in the planned TCR1HF series, available today, are TCR1HF18B, TCR1HF33B and TCR1HF50B with fixed outputs of 1.8V, 3.3V and 5.0V respectively. Devices are in the pipeline at 2.5, 2.8, 3.0, 3.1 and 3.2V. Maximum drop-out over the -40 to 125°C ...

Nordic Semiconductor is aiming at cellulat IoT with a system-in-package which puts an RF front-end and a power chip alongside its nRF91 modem and CPU chip. Called nRF9161, it is a globally pre-certified IC “that makes it possible to select either cellular IoT connectivity using the secure cellular infrastructure or use DECT NR+ to realise private 5G networking”, according to ...
