Review of Koogeek BP2 Bluetooth Blood Pressure Monitor

Koogeek BP2 is an FDA approved smart blood pressure monitor that connects over Bluetooth to your Android or iOS smartphone, or WiFi to the cloud. The company sent me a sample for evaluation, so let’s get started right away. Koogeek BP2 Unboxing The device is sent in a cardboard package with Koogeek brand… and some more derails about the specifications on the bottom of the package. I asked the company to confirm about FDA approval, and they told me to look for K134029 on the FDA website, which lead me to this document testing Shenzhen Belter Health Management and Analysis ePA-46B, and comparing it to the results of Omron HEM-7200-Z (BP742) with the conclusion being that: The Belter Blood pressure meter (ePA-46B) is substantially equivalent to the predicate devices. Koogeek BP2 is the same as Belter ePA-46B, but just rebranded, and with a different mobile app. In the package will find […]

7″ LCD Display with HDMI input, Audio output Launched for Orange Pi (and Other) Boards

If you want a cheap and simple way to add a screen to your development board, there are some 7″ displays with HDMI inputs that costs under $30 shipped. But Shenzhen Xunlong has decided to make their own 7″ LCD display with HDMI input and audio output, and sell for $22 + shipping. The company only provided minimal technical information about the board and display: Display  – 7″ TFT LCD with 1024×600  resolution Video & Audio Input – HDMI Audio Output – 3.5mm audio jack Power Supply – 5V via micro USB port If we look at a closer picture of the board, we’ll see they used Lontium LT8619B, but the company’s website is down… The board also features three different connectors for displays, so they probably have other displays planned. While the company claims the display is made for  Orange Pi H3 boards, it should really work with any […]

Hantek PSO2020 is a $53 USB Oscilloscope Pen

I previously covered IkaScope & Aeroscope oscilloscope probes that are both portable and connect wirelessly to your mobile device or computer over respectively WiFi or Bluetooth. The former has slightly better specifications and sells for 300 Euros, while the latter goes for $200 US with 20 MHz bandwidth and 100 MSps capabilities. Several people mentioned it was more expensive than they were prepare to pay, but I’ve been informed about another portable solution: Hantek PSO2020 oscilloscope pen with about the same key specifications as Aeroscope 100A, except it relies on a USB port instead of a wireless connection. This also means it does not need a battery, and sells for much less at $53.20 including shipping. Hantek PSO2020 specifications: Analog Bandwidth  – 20 MHz Sample Rate – 96 MSps Host Interface – USB 2.0 port Input Range – +/-50 V range Input Sensitivity – 20mV/div to 50V/div Offset Range – […]

Unofficial List of TV boxes Running Android TV OS

Most TV boxes run a modified version of Android operating system for smartphone, and devices based on Google’s Android TV are harder to find, and often country specific since they are tied to local streaming services. Yesterday, I was searching for boxes based on Marvell Armada 1500 Ultra SoC, and first found a couple in Spain and the US, but eventually found a bunch more when I discovered somebody was keeping track of all/most Android TV devices in a page hosted by Google but with no actual affiliation with Google. The devices are sorted in three categories: Pay TV Providers, usually only sold in a specific country with programs in the local language, and a fairly long list Streaming / Gaming – Those are the most famous Android TV TV boxes like Xiaomi Mi Box or Nvidia Shield Android TV with only 6 models in that list TVs with Android […]

Wemos introduced the first low cost ESP32 board with LOLIN32 board going for $6.90 plus shipping in April, but the company is now back with a new Lite version of the board switching ESP-WROOM-32 module with their own design around ESP32 Rev 1 chip (with various silicon bug fixes), and a lower $4.90 price tag to which you need to add ~$2 for shipping.

Intel unveiled the Compute Card at the very beginning of the this year, without that many details, except it would included a 7th Gen Intel Core, memory, storage and wireless connectivity, and connect compliant dock with a new standard connector featuring USB-C and extra I/Os.
