ESP32 UWB board features DW1000 module for accurate indoor positioning

ESP32 UWB board

FiRa “Fine Ranging” UWB technology was introduced a few years ago and is now found in devkits and Apple U1 chip. Makerfabs ESP32 UWB board provides another option with Espressif ESP32-WROVER-32 or ESP32-WROOM-32 WiFi & Bluetooth module combined with a Decawave DW1000 module for precision tracking. Makerfabs explains the board acts like a continuously scanning radar that locks onto another device (called Anchor, since it’s usually in a fixed location) and communicates with it to determine the distance between objects by calculating the time of flight (ToF) between devices, or in other words, the roundtrip time of challenge/response packets. ESP32 UWB board specifications: Wireless modules: WiFi & Bluetooth LE – ESP32-WROVER-32 or ESP32-WROOM-32 module with ESP32 dual-core processor @ 240 MHz UWB – B&T BU01 module based on Decawave DW1000 chip; IEEE802.15.4-2011 UWB compliant wireless transceiver module with a precision of 10cm indoors, a data rate of up to 6.8 […]

Beelink GTi11 Review – Part 1: Tiger Lake mini PC with Windows 11

Beelink GTI11 review

Beelink’s GTi11 is the latest offering in their ‘GT’ series of slightly larger mini PCs that are notable for expandable storage configurations together with multiple ports and characterized by including a fingerprint scanner. Featuring Intel’s 11th generation Tiger Lake processors, Beelink kindly sent an i5 version for review which I will undertake in three parts. In this first part, I’ve looked at Windows performance and the second part will cover Ubuntu with the third part looking at various configuration mods. Beelink GTi11 Hardware Overview The GTi11 physically consists of a 168 x 120 x 39mm (6.61 x 4.72 x 1.54 inches) rectangular metal case. As an actively cooled mini PC, it uses Intel’s ‘10 nm SuperFin’ Tiger Lake processors and the review model included an i5-1135G7 which is a quad-core 8-thread 2.50 GHz Core processor boosting to 4.20 GHz with Intel’s Xe Graphics. The front panel has an illuminated power […]

$65 dual Wi-Fi HaLow gateway kit extends network range by hundreds of meters

STK-AH9066 802.11ah gateway

I’m starting to better understand what Wi-Fi HaLow (aka 802.11ah) is for, after seeing a kit with two WiFI HaLow gateways used to wirelessly extend the range of Ethernet connected nodes on the LAN, including IP cameras, to several hundred meters, far more than your typical WiFi repeater, but at the cost of a lower bitrate. Yesterday, I wrote about Halo TD-XPAH, the first easily procurable 802.11ah WiFi HaLow development board I had seen, since the introduction of the new standard in 2014. But I was told another lower-cost HaLow board had been available for a few months on Alibaba, and while I failed to find it on Aliexpress, I discovered a pack with two WiFi HaLow to Ethernet gateway that could easily help extend the range of WiFi nodes like security cameras and selling for about $65 shipped. STK-AH9066 WiFi HaLow gateway specifications: Wireless 802.11ah Wi-Fi HaLow standard 902-930MHz […]

Qualcomm IPQ8072A networking SBC supports dual 10GbE, WiFi 6

DR8072 V1 SBC Qualcomm IPQ8072

DR8072 V01 is a networking SBC based on Qualcomm IPQ8072A communication processor, with two 10GbE interfaces, one through an SFP cage and the other through an RJ45 connector, plus four Gigabit Ethernet ports, and 4×4 MIMO WiFi 6 connectivity (AX3700). Based on Qualcomm AP.HK09 reference design, the board follows Wallys Communications’ DR8072A embedded router board introduced earlier this year, also based on Qualcomm IPQ8072, but equipped with two 2.5 GbE interfaces and WiFi 6 connectivity. DR8072 V1 specifications: SoC – Qualcomm Atheros IPQ8072A quad-core Arm Cortex-A53 @ 2.2 GHz part of Qualcomm Networking Pro 1200 Platform System Memory – 512MB DDR4 2400MHz 16-bit interface (option up to to 2GB RAM) Storage – 8MB NOR flash, 256MB NAND flash Networking Wireless On-board 4×4 2.4GHz MU-MIMO OFDMA 802.11b/g/n/ax, max 17dBm per chain, up to 1147Mbps On-board 4×4 5GHz MU-MIMO OFDMA 802.11a/n/ac/ax, max 17dBm per chain, up to 2475Mbps Frequencies – 2.412 to […]

UP Xtreme i11 Edge Compute Enabling Kit Review – Part 1: Unboxing and Teardown

Review UP Xtreme i11 Edge Compute Enabling Kit

AAEON’s UP Xtreme i11 Edge Compute Enabling Kit is an industrial mini PC based on the UP Xtreme i11 Edge single board computer powered by a choice of Tiger Lake processors and designed for edge applications for the industry. I recently got contacted by AAEON who sent me a version of the Edge Compute Enabling Kit with an Intel Core i7-1185GRE SoC, 16GB RAM, and a 128GB SSD pre-loaded with Ubuntu. I’ll start the review by checking out package content and interfaces, and teardown the hardware, before testing is with Ubuntu next month. UP Xtreme i11 Edge Compute Enabling Kit unboxing Customs took a keen interest in the package, opened it to check it out, and resealed it. But I eventually got the package, and customs their money… The package includes a 12V/6A power supply together with a power cord, EU type in my case, but the company will ask […]

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. You’ll find detailed instructions with the list of parts, […]

Reolink Go Plus 4G smart security camera with solar panel – Unboxing and first setup

Reolink Go Plus 4G LTE IP Camera

I’ve received several Reolink IP cameras either connected over WiFi or Ethernet, but the company has just sent me Reolink Go Plus 4G security camera together with a solar panel that would let me access the camera from anywhere with cellular network connectivity. Reolink Go Plus integrates a 4MP camera and supports person and vehicle detection, just like Reolink RLC-810A model I reviewed earlier this year. I have three Reolink cameras, and I’m somewhat satisfied except that the connection to WiFi cameras is often unreliable, and I have to rely on Cloud backup to play video captures most of the time. The Ethernet-connected Reolink RLC-810A has a much more reliable connection. So I’ll have to see if the Reolink Go Plus camera is more accessible over 4G LTE than WiFi cameras. I’ll start the review by checking out the packages and going through the initial setup for the Reolink Go […]
