SmartBug smart switch integrates neatly into in-wall sockets (Crowdfunding)

SmartBug Smart Switch

SmartBug is a smart switch based on ESP32 wireless SoC, equipped with several sensors to measure temperature, humidity, power usage, and listen to sounds. It is designed to fit neatly into most in-wall sockets found around the world. Each SmartBug relies on mesh networking to communicate with each other and extend the range, WiFi for Internet connection, and Bluetooth low energy (BLE) to control additional devices without the need for any additional hub. SmartBug’s key features: MCU – 32-bit dual-core microcontroller with WiFi, wireless mesh, Bluetooth LE Connectivity 2.4GHz WiFI 4 Wireless mesh to let SmartBug act as a signal repeater Bluetooth 4.0 and BLE to control home appliances Audio Digital microphone for voices commands, baby crying (only enable if the plugin is downloaded in the app).

NuCurrent showcases NFC charging at 3W, data rates up to 848 kb/s

NuevaNFC 3W power

The NFC Forum approved the Global Wireless Charging (WLC) specification last year with the new standard making it possible to wirelessly charge small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt. The NFC WLC currently specifies power levels ranging from 100mW – 1W transmitted and data rates up to 106 kb/s, but NuCurrent claims to have gone beyond WLC specs, delivering over 3x more wireless power and over 8x faster data speeds. This was achieved with the company’s NuEva Development Platform for Near-Field Communication (NFC) Wireless Charging technology that provided up to 3W of power received (as opposed to just transmitted in the WLC specification) and data rates of up to 848 kb/s. NuCurrent expects the higher NFC charging power and data rates to enable new applications for small, space-constrained devices including wrist-wearables, smartwatches, styluses, […]

$5 board eases ATX power supply connection to single board computers

ZJ-012 ATX Power Supply single board computer

Many people have ATX power supplies from older desktop PCs that they may want to reuse with Arduino boards, Raspberry Pi, or other single board computers. It’s indeed possible to do so by trimming some cables and making a circuit to protect the board from over-voltage or over-current. But ZJ-012 adapter board offers a simpler solution with a 24-pin header for the ATX power supply, terminal blocks for connection to the target board, some fuses for protection, and a header to connect an on/off button. JZ-012 (also known as JZ-024) ATX power adapter board’s key features and specifications: Power Input – 20-pin or 24-pin computer ATX power supply Power output – 9-pin terminal block with +3.3V, +5V, -12V, +12V, +5V, GND with fuses for each power outputs On/Off control – Toggle switch or header for external button/switch (shorted for power on) Misc – Power indicator (red LED) Dimensions – 70 […]

USB Type-C Specification 2.1 allows up to 240W Extended Power Range (EPR)

USB PD EPR Flow 240W

Many devices have switched from a Micro USB port or a power barrel jack to the USB-C port in recent years, as the latter allows for higher currents, and up to 100W power input in USB PD (Power Delivery) compliant systems. While 100W will be more than enough for most devices, more power-hungry devices or systems still need a power brick, for example, gaming laptops and mobile workstations. But the USB Type-C specification 2.1 aims to change that by upping the maximum power to 240W. As noted by Benson Leung in a Reddit Thread the part of the specification that handles the 240W power is the EPR (“Extended Power Range”) that defines requirements for cables, chargers, and devices: 3.11 Extended Power Range (EPR) Cables 3.11.1 Electrical Requirements Extended Power Range cables have additional requirements to assure that these cables can deliver the full defined voltage and current range for USB […]

BLUETTI EP500 is a power bank & UPS for home appliances (Crowdfunding)

Bluetti EP500

Many people are using a power bank to extend the battery life of their mobile device(s), and there are also laptop power banks which higher capacity and support for 12V and/or 19-20V besides the usual 5V. But BLUETTI EP500 & EP500Pro go up a notch as the systems aim at powering multiple home appliances or be used as UPS in case of power failure, or whenever you need to use tools or appliances away from the mains. BLUETTI EP500 & EP500Pro specifications: Control system based on Texas Instruments C2000 dual-core Arm+DSP real-time microcontroller AC Rated Power EP500 – 2000W (peak 4800W less than 500ms) EP500Pro – 3000W (peak 6000W less than 500ms) Power Input EP500 600W max, 100-264V AC via AC input – Charging time around 9 to 10 hours 1,200W max via PV input or T500 input (55-145V DC, 20A) – Charging time around 5 hours with solar panels […]

PinePower 120W desktop power supply features display, USB PD, QC 3.0 and wireless charging

Desktop Power Supply Qi Wireless Charging

Pine64’s January update includes the launch of PinePhone with Mobian operating system, some limited details about the upcoming Quartz64 RK3566 SBC that will ship with 4 to 8GB RAM, and other news about all their products. There’s not enough details yet to write a post about Quartz64, but another product caught my eyes: PinePower. Yes, Pine64 is now offering power supply, and last month they presented PinePower 65W GaN power adapter that looks similar to MINIX NEO P1 power supply, albeit slightly larger. But I find the desktop version of the power supply even more interesting with an integrated display that shows voltage and current for each port, and also adds Qi wireless charging. PinePower “Desktop” version specifications: Display – Shows individual port voltage and current status USB charging ports 1x USB Type-C PD port up to 65W output with support for 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.25A 1x QC 3.0 […]
