A compact Raspberry Pi RP2040 WiFi board – Meet $12.95 Wio RP2040 mini

Seeed Studio has launched another Raspberry Pi RP2040 WiFi board with the compact Wio RP2040 mini development board that provides a cheaper and more compact alternative to ESP32 based Pico Wireless carrier board and Arduino Nano RP2040 Connect, albeit at the cost of providing fewer I/O pins, and lacking Bluetooth LE. Wio RP2040 mini dev board specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller up to 133 MHz with 264 kB of embedded SRAM Storage – 2MB QSPI Flash Memory WiFi – 2.4 GHz 802.11b/g/n WiFi 4 supporting AP & station modes USB – USB 1.1 Type-C host/device port for programming Expansion – 2x 14-pin headers with 20x multifunctional GPIO pins supporting PIO and PWM, 2x UART, 4x ADC, 2x SPI, 2x I2C.

Sonoff & Tuya smart plugs found to transmit unencrypted passwords

There are many low-cost smart plugs based on ESP8266 that provide a convenient way to control lights or home appliances with your smartphone. But cybersecurity firm A&O IT Group found vulnerabilities in ITEAD’s Sonoff S26 and Ener-J Wi-fi (Tuya) smart plugs that would allow an attacker to easily access your wireless network. The first security vulnerability is pretty common and hard to exploit since it’s only a concern during the setup. Sonoff S26 starts itself into access point mode with ITEAD-1001xxxxxx SSID, and is set up through the eWelink app with the user not needing to know the password. But with older firmware is was needed, so ITEAD still shares the default password: 12345678 in the user manual, and it can be used to connect to the smart plug by anyone. But once configured, it’s not accessible anymore as the smart plug should be in client mode connected to your […]

Why you should request open-source software for your IoT devices

PineTime open-source software Gadgetbridge

I usually think of open-source hardware and/or software are enabling skilled people to more easily fix bugs, improve on the design, get feedback from the community, etc… But in a world where IoT devices become more prevalent, there’s another reason why you should request open-source software: Long term support. What made me think about are two things. The first one if that I own WeLoop Hey 3S smartwatch, which I love and wear since March 2018. That’s quite a feat since most cheap devices I own often only last a few months or a year or so. I’m also used to the watch face and Weloop app interface. So what’s the problem exactly? WeLoop company closed on December 31, 2019, and while the app worked fine for about a year after that, recently I have been unable to login to the app to access my data and/or update settings for […]

Raspberry Pi CM4 based Exo Sense Pi multi-sensor device gets optional earthquake sensor

Sfera Labs’ Exo Sense Pi is a device with multiple environmental sensors based on the 2GB version of the Raspberry Pi CM4 module designed for residential and commercial applications such as environmental monitoring and data gathering, BLE positioning, indoor people and assets tracking, rooms management and access control, voice control, and more. The Exo Sense Pi devices include optional WiFI 5 and Bluetooth 5.0 LE connectivity depending on the RPI CM4 module selected, and ships with temperature, humidity, air quality (VOC), light intensity, microphone, and PIR motion sensors by default, but there’s also an optional earthquake sensor. Exo Sense Pi specifications: SoM – Raspberry Pi CM4 (16GB eMMC flash) or CM4 Lite module with 2GB RAM by default. But obviously compatible with other models. Storage – MicroSD card socket for CM4 Lite module Wireless connectivity – 2.4 GHz, 5.0 GHz IEEE 802.11 b/g/n/ac wireless; Bluetooth 5.0, BLE depending on installed […]

HybridOS is an open-source operating system designed for smart IoT devices and cloud computing environment

As I wrote about the “Summer 2021 of Open Source Promotion Plan” earlier, I noticed a new open-source operating system called HybridOS described as “totally new” and designed for “smart IoT devices and cloud computing environment”. It’s actually more of an ecosystem than an operating system, as it offers three main components with a device side running on devices running Linux kernel or another POSIX-compatible kernel, a server side running on servers in the cloud, and a client side to manage the cloud and devices from Windows, Linux distributions, iOS, or Android. HybridOS Device Side relies on several open-source projects including: hiWebKit, the HybridOS derivative of WebKit: hiACEJS, the HybridOS derivative of OpenHarmony ACELite hiViewRenders, the renderers for hiview tag of hiWebKit hiShell, the app running environment (the shell) Various Graphics stacks including hiMesa, the HybridOS derivative of Mesa hiCairo, the HybridOS derivative of Cairo: hiDRMDrivers, DRM Drivers for HybridOS […]

ClusBerry-2M Industrial IoT controller takes two Raspberry Pi Compute Modules 4

Earlier this year, Techbase introduced the ClusBerry 9500-CM4 cluster system for industrial IoT that can take up to eight Raspberry Pi Compute Modules 4 housed in a DIN rail enclosure. But for smaller projects and IoT prototyping, the company has now designed ClusBerry-2M, a smaller cluster device including two independent ModBerry I/O mainboards and two Compute Module 4’s that’s equivalent to two ModBerry 500-CM4, but with support for software cluster management tools such as Docker and K3s Lightweight Kubernetes. The company did not share the full ClusBerry-2M specifications, but we can derive most of the features from the photos, previous products features, and the announcement: SoM – 2x Raspberry Pi Compute Module 4 with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, up to 32GB eMMC flash. Storage – 2x M.2 slots for NVMe SSDs Video Output – 2x HDMI 2.0 ports Connectivity 4x Gigabit Ethernet […]
