Onera Health unveils Onera Biomedical-Lab-on-Chip with over a dozen sensor inputs

Onera Health, a Dutch-American MedTech company has just introduced the Onera Biomedical-Lab-on-Chip, an ultra-low-power biosignal sensor hub for wearable health, following their earlier work on sleep diagnostic solutions. The Arm Cortex-M4F based Onera ONE010 chip embeds a multi-channel sensor readout system with integrated data processing, power management, and interfacing features. It features biomedical inputs with 10 readouts for ExG, covering EEG, ECG, EMG, and EOG, 2 bioimpedance readouts, and 2 readouts for photoplethysmography, as well as digital filters and accelerators to process the data from the sensors. The microcontroller is also equipped with several standard wired interfaces such as UART, SPI, I2C, and I2S, operates from a single power source between 0.8V and 3.6V, and the company says a large amount of SRAM and embedded FLASH is available. I’ve managed to obtain a more readable block diagram and that means 320KB of SRAM and 768KB of flash. We can also […]

Solar-powered Bluetooth headset with Powerfoyle nano-material band remains charged at all times

Blue Tiger Solare is a solar-powered Bluetooth headset that you may never need to charge thanks to a Powerfoyle solar cell headband comprised of a “nano-material that transforms any outdoor and indoor light into clean, endless energy”. Solare Bluetooth 5.1 headset is said to be military-grade (MIL-STD-810), offers 97% noise cancellation, and is mostly designed for “road warriors” who may require a Bluetooth headset that’s charging continuously. I initially thought it would probably work better for hikers, bicycle and motorbike riders, than car drivers unless we’re talking about convertibles, but Blue Tiger caters to professional truck drivers. Solare highlights: Bluetooth 5.1 with up to ~90 meters range High-quality speaker Microphone with 97% noise cancellation Works with Sir and Google Assistant Endless Battery Life with Powerfoyle solar cell flexible headband Temperature Range – -40°C to +50°C Certifications IPX4 ingress protection rating MIL-STD-810 for extreme environments and ruggedness Solare solar-powered Bluetooth headset […]

ESP32 CAN board fits into OBD-II dongle, supports auto shutdown

RejsaCAN-ESP32 is a small board based on ESP32-WROOM-32 WiFi (and Bluetooth) module with a CAN interface that fits into a 3D printed OBD-II dongle for easy installation into most cars. Magnus Thomé has already published several automotive projects, notably for car racing with a system that checks real-time tire temperature, and he designed RejsaCAN-ESP32 board so that it can be plugged directly into his car with support for 5-15V input voltage, and also includes an auto-shutdown option to prevent battery drain by monitoring the battery voltage in the car. RejsaCAN-ESP32 specifications: Wireless module – ESP32-WROOM-32 module with a dual-core ESP32 processor @ 240 MHz with 2.4 GHz WiFi 4 and Bluetooth 4.2 connectivity, PCB antenna, 32Mbit SPI flash USB – 1x USB-C port for power and programming via CP2104 USB to TTL chip Expansion – 15-pin header with 3x GPIO, SPI, I2C, analog input, PWM or analog output, CAN bus […]

Beelink Expand F USB-C dock takes M.2 SSD and 2.5-inch SATA drive

Beelink has previously introduced USB docks with the Expand X smartphone dock and Expand M with an SSD. The company’s latest Beelink Expand F USB-C dock looks really like a mini PC from the outside with the usual USB, HDMI, Ethernet, and audio ports, and it can also be fitted with an M.2 2280 SATA SSD and/or a 2.5-inch SATA drive. It can be useful to add PC-like connectivity to a smartphone or add additional storage to a laptop without cluttering your desk with multiple USB drives, and/or potentially saving some USB ports on the host machine. Beelink Expand F specifications: Storage Options No storage, i.e. bring your own SATA drive(s) via M.2 socket up to 440 MB/s and/or 2.5-inch SATA bay 512GB SATA III M.2 SSD 512GB SATA III M.2 SSD plus 1TB SATA HDD Video Output – 2x HDMI ports up to 4K resolution Audio – 3.5mm audio […]

Pine64 launches PinePhone Keyboard case, back covers with LoRa radio, fingerprint scanner, wireless charging

Pine64’s PinePhone Linux smartphone and its successor, the upcoming PinePhone Pro, are designed to be modular and extensible with a PinePhone Keyboard case prototype showcased here in April 2021 and aimed to transform the phone into what looks like a PDA. The design has now been refined, and Pine64 has just launched the PinePhone (Pro) keyboard case for $49.99, together with three back covers with either a LoRa module, a fingerprint scanner, or Qi wireless charging for $9.99 to $24.99 depending on the model. All are now available on Pine64 store. PinePhone (Pro) Keyboard Case Key features and specifications: ISO QWERTY layout with 54 keys in 5 rows. Note the key caps can be rearranged, so you could easily make an AZERTY or QWERTZ keyboard for example 180° hinge for two-hand typing on surface or thumb-typing when held Pogo pin connector to connect to PinePhone (Pro) smartphone USB – USB […]

Year 2021 in review – Top 10 posts and statistics

As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]

Mico – A USB microphone based on Raspberry Pi RP2040 MCU

Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller has found its way into Mico, a compact USB microphone with a PDM microphone providing better quality than cheap USB microphones going for one or two dollars or even 5 cents shipped for new Aliexpress users. The project started when Mahesh Venkitachalam (Elecronut Labs) was doing audio experiments with Machine Learning on the Raspberry Pi, and found out USB microphone dongles were extremely noisy with poor (distance) sensitivity, so he completed the project with a high-quality I2S microphone instead. He then had the idea of making his own USB microphone and found out Sandeep Mistry had already developed a Microphone Library for Pico, so he mostly had to work on the hardware that’s how Mico Raspberry Pi RP2040 USB microphone came to be. Mico specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 264KB SRAM Storage – 128Mbit […]
