Most power banks are made of Lithium batteries that charge in 3 to 4 hours and are good for around 500 charge cycles. But Elecjet Apollo Ultra is a different beast equipped with a 10,000 mAh Graphene battery that enables fast charging in just 27 minutes and offers a much longer lifespan with over 2,500 charge cycles. In other words that means Apollo Ultra power bank is 5x faster and lasts 5x longer than most lithium-based power banks. Another way to look at it is that this graphene-enhanced 10,000mAh power bank can gather enough power in just 7 minutes to fully charge your phone. It can fast-charge your phone up to three times, charge two devices at once, and passthrough charging lets you charge Apollo Ultra at the same time. Elecjet Apollo Ultra specifications: Battery Capacity – 10,000 mAh or 40 Wh Full Charge Time – 27 minutes USB ports […]
Raspberry Pi UPS HAT takes two 18650 batteries (Crowdfunding)
Raspberry Pi UPS solutions have been available for years with products like PiJuice Zero, PiVoyager, or LiFePO4wered/Pi+. But the team at SB Components has designed another UPS HAT for Raspberry Pi with a holder for two 18650 batteries. The HAT is designed for 5V operation up to 2.5A, connects with the Raspberry Pi SBC through the I2C bus from the 40-pin GPIO header, and is equipped with a 0.91-inch OLED for information display. UPS HAT for Raspberry Pi specifications: Power Input – 8.4V/2A via DC jack Power Output – 5V up to 2.5A through LDO chip (GPIO header and 2x USB ports) Display – 0.91-inch OLED Host interface – I2C Misc – On/Off switch Battery support 18650 Lithium battery (not included) via holder for two batteries Battery reverse indicator Charging and voltage monitoring via TI INA219 I2C chip Battery voltage balancing with Hycon HY2213 Battery protection IC (Hycon HY2120) Dimensions […]
OS and Memory Impact on Mini PC Gaming Performance
This article looks at what the effect of running a different operating system or having more memory has on similarly spec’d Intel and AMD mini PCs when gaming. Note: This article has been updated and corrected as a result of reader feedback and additional testing. It was inspired by having built and tested a pseudo ‘Steamdeck’ running Manjaro on an AMD-based mini PC with 16GB of memory, which made me wonder what the performance would be like using Windows 11. Initial results were surprising because Windows appeared much slower. As I’d previously heard of performance improvements when using 64GB of memory I swapped out the currently installed 16GB memory and immediately saw improved results. As I’d never observed such a dramatic performance increase on Intel mini PCs just through increasing the memory I decided to explore further by testing gaming performance on similar Intel and AMD mini PCs when using […]
NOVELDA UWB X4 sensor can detect submillimeter movements
We’ve just written about an ESP32 UWB board equipped with an ultra-wideband module designed for indoor positioning with about 10 centimeters accuracy, which should be good enough for many applications, but it turns out UWB sensors can be made to be much more accurate. NOVELDA has just announced the UWB X4/X4F103 sensor and development kit that can detect submillimeter micro-movements such as breathing for human presence detection and does so at a really low power consumption of under 2mW. NOVELDA UWB X4 (X4F103) highlights: High-precision ranging for accurate distance measurement and absolute range bounding based on patented impulse radar technology Low power consumption below 2mW, and no co-existence issues with other sensors Wide detection zone for accurate detection with up to 180-degree field of view Up to 5m range Works through plastic and glass or layers of clothing Package – 12 x 12mm sensor A big difference compares to Decawave […]
Phased out Raspberry PI CM4 quad SATA carrier board becomes open-source hardware
Wiretrustee carrier board for Raspberry Pi CM4 was unveiled about one year ago with four SATA connectors to help people build their own 4-bay NAS. Unfortunately, the company decided to discontinue the project due to the semiconductors market situation. The good news is the board is now open-source hardware with all resources shared publicly including the Allegro schematics and PCB layout, Gerber files, 3D models for the heatsink, and case designs for 2.5-inch or 3.5-inch drives. All files are available under “CERN Open Hardware Licence Version 2 – Permissive”. Here’s a quick reminder about the Wiretrustee board specifications: Supported SoM – Raspberry Pi Compute Module 4 and 4 Lite Storage 4x SATA 2.0 via Marvell 88SE9215 (PCIe 2.0 x1 to 4 6Gb/s SATA ports, no HW RAID) MicroSD card slot Video Output – HDMI 2.0 up to 4Kp60 Networking – 1x Gigabit Ethernet port USB – 2x USB 2.0 ports […]
$1.8 XT-ZB1 Zigbee & BLE devkit features BL702 RISC-V module
Bouffalo Labs BL702 is a 32-bit RISC-V microcontroller with a 2.4 GHz radio for Zigbee 3.0 and Bluetooth 5.0 LE connectivity that we first found in the Sipeed RV-Debugger Plus UART & JTAG debug board that did not make use of the radio at all. But a BL702 development kit was brought to my attention, with the XT-ZB1 devkit equipped with a Zigbee & BLE module of the same name, and sold for just $1.80 per unit on Aliexpress. Shipping adds $4.63 where I live, but they also offer packs of 5 or 10 with the same shipping fee, meaning if you buy 10 the total cost should be around $22 including shipping, or around $2.2 per board. Alternatively, the module alone goes for $1. XT-ZB1 devkit specifications: XT-ZB1 wireless module with MCU – BL702C 32-bit RISC-V microcontroller @ 144 MHz with FPU, 132KB RAM, 192KB ROM, 1Kbit eFuse Storage […]
KiCad 6.0.0 released with revamped user interface, thousands of changes
It took around 3.5 years of development to release KiCad 6.0.0 open-source EDA suite, as the previous major release, KiCad 5.0.0, was introduced in July 2018. KiCad 6.0.0 comes with a refreshed user interface that’s supposed to reduce the barriers of entry for new users and users switching from other design software with notably the schematic and PCB editors now feeling like being from the same program instead of completely different tools. As noted by the developers, it’s difficult to summarize all the changes because of the thousands of updates made between KiCad 5 and KiCad 6, but here are some highlights: Revamped schematic editing with the object selection and manipulation paradigm as the PCB editor, and several new features such as net classes, one-click wire start, intersheet references Brand-new schematic and symbol library file format allowing embedded symbols Redesign of the PCB design tool with new options such as […]
UGOOS UT8 PRO – An RK3568 TV box with 8GB RAM, 64GB storage
UGOOS UT8 PRO is the first TV box I’ve seen with a Rockchip RK3568 processor, if we exclude Firefly Station P2 that’s more like an Arm Linux mini PC. The device runs Android 11 and is equipped with 8GB RAM, 64GB eMMC flash, and offers WiFi 6 connectivity. There’s also the “UGOOS UT8” with basically the same features except it ships with 4GB RAM and 32GB flash, and a dual-band WiFi 5 and Bluetooth module. We previously had seen TV boxes and mini PCs with the similar Rockchip RK3566 SoC in T95 Plus, H96 Max, and Zidoo M6, and the only reason for going with RK3568 in UGOOS UT8 (PRO) should be the extra USB 3.0 host/OTG interface, adding to the USB 3.0 host interface found in both RK3566 and RK3568 processors. UGOOS UT8 (PRO) specifications: SoC – Rockchip RK3568 with a quad-core Cortex-A55 processor @ up to 1.8/2.0GHz, Arm […]
