Lightweight wireless AR Smart Viewer reference design is powered by Snapdragon XR2 platform

Snapdragon XR2 wireless AR smart viewer reference design

Qualcomm unveiled a new Wireless AR Smart Viewer Reference Design powered by the Snapdragon XR2 platform last week with very few details, but the company has now demonstrated the system to some members of the press, so let’s have a closer look. The reference design aims to provide a similar level of performance as a headset connected to PC or premium smartphone, but with some of the processing offloaded to the Snapdragon XR2 processor, thereby eliminating the need for a cord while still achieving lag-free experiences in combination with the Qualcomm FastConnect 6900 WiFi 6 and Bluetooth 5.3 solution. It is supposed to offer a 40% thinner profile and a more balanced weight distribution than the earlier Snapdragon XR1 smart glasses reference design.   Wireless AR Smart Viewer reference design specifications: SoC – Qualcomm Snapdragon XR2 with Octa-core processor with 1x Kryo Gold prime @ 2.84 GHz + 3x Kryo […]

5G RedCap leverages 5G features, limits bandwidth to 85Mbps for industrial IoT applications

5G Evolution 5G RedCap, LPWA, eMBB

5G is often associated with Gigabit speeds when found in mobile handsets or connected laptops, while there’s also 5G LPWA for battery-powered IoT devices. 5G RedCap, which stands for Reduced Capability, offers a middle ground for industrial IoT applications that keep some 5G features such as low latency, low power consumption, enhanced security, and network slicing while limiting the bandwidth to around 85 Mbps. 5G RedCap, also called NR Lite, will be part of 3GPP Release 17 scheduled for later in 2022, and further improved in Rel 18 in 2023. It will be first found in applications currently relying on LTE Cat 1 through Cat 4, and can be considered a light version of the 5G standard. An article on Telit says Rel 18 will specifically address the low-power wide-area network (LPWAN) segment currently carried seamlessly (e.g. no hardware changes required) in 5G by LTE-M and NB-IoT. I found out […]

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

Onera Biomedical Lab-on-Chip

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 […]

DIY Pip-Boy wrist computer is equipped with Adafruit Feather RP2040 board

RP2040 Pip-Boy wrist-computer

The Pip-Boy is a (virtual) personal information processor found in Fallout post-apocalyptic role-playing video games. But John Edgar Park decided to bring the wrist computer to (real) life combining an Adafruit Feather RP2040 board, a round IPS TFT color display, directional buttons, a joystick, and a battery. The Raspberry Pi RP2040 based Pip-Boy is programmed with CircuitPython and the demo code is a slide-show with navigation controls, but you could obviously adapt the code to your needs. The main components are: Black Adafruit Feather RP2040 board Adafruit Joy FeatherWing adding buttons and a joystick Adafruit 1.69″ 280×240 Round Rectangle Color IPS TFT Display FeatherWing Tripler mini kit to connect the two boards above and the display 3D printed enclosure A 3.7V/420mAh LiPo battery for power On/off switch The design is completed with some headers, stand-offs, screws, and a nylon watch strap.
