The Eclipse Oniro Project aims to deliver consumer & IoT software that works across multiple platforms

Several of the embedded talks at FOSDEM 2022 mention the “Eclipse Oniro Project”. I had never heard about that project from the Eclipse Foundation, so let’s see how they describe it: Oniro is an Eclipse Foundation project focused on the development of a distributed open source operating system for consumer devices, regardless of the brand, model, make. Oniro is a compatible implementation for the global market of OpenHarmony, an open source operating system specified and hosted by the OpenAtom Foundation. Designed with modularity in mind, Oniro offers greater levels of flexibility and application portability across the broad spectrum of consumer and IoT devices — from tiny embedded sensors and actuators, to feature rich smart appliances and mobile companions. As a distributed and reusable collection of open source building blocks, Oniro enables compatibility with other open source technologies and ecosystems. Through close collaboration with projects and foundations such as OpenHarmony from […]

Board with 25 RGB LEDs is offered with ESP32-C3 or ESP32-Pico-D4

In case you are in need of a tiny WiFI or Bluetooth-connected board with an RGB LED matrix, two have shown up on Banggood with basically the same 25 RGB LED design , except “C3FH4 RGB” board is based on ESP32-C3 RISC-V SoC, while the other, named “PICO D4 RGB“, features ESP32-Pico-D4 SiP (System-in-Package). The boards are cute and the main purpose is probably for decoration/ornament, but I’d imagine if you purchase a few they could also be used as an experimentation/education platform for mesh networking, using the ESP Mesh Development Framework (ESP-MDF) for instance. C3FH4 RGB / PICO D4 RGB board specifications: SoC/SiP C3FH4 RGB board – ESP32-C3FH4 SoC with RISC-V core @ 160 MHz, 4MB flash, 2.4GHz Wi-Fi, and Bluetooth 5 LE with Long-Range support PICO D4 RGB board – ESP32-PICO-D4 system-in-package with ESP32 dual-core Xtensa processor @ 240 MHz, 2.4GHz Wi-Fi and Bluetooth dual-mode, 4MB flash Ceramic […]

ESP32 CAN board fits into OBD-II dongle, supports auto shutdown

RejsaCAN-ESP32 is a small board based on ESP32-WROOM-32 WiFi (and Bluetooth) module with a CAN interface that fits into a 3D printed OBD-II dongle for easy installation into most cars. Magnus Thomé has already published several automotive projects, notably for car racing with a system that checks real-time tire temperature, and he designed RejsaCAN-ESP32 board so that it can be plugged directly into his car with support for 5-15V input voltage, and also includes an auto-shutdown option to prevent battery drain by monitoring the battery voltage in the car. RejsaCAN-ESP32 specifications: Wireless module – ESP32-WROOM-32 module with a dual-core ESP32 processor @ 240 MHz with 2.4 GHz WiFi 4 and Bluetooth 4.2 connectivity, PCB antenna, 32Mbit SPI flash USB – 1x USB-C port for power and programming via CP2104 USB to TTL chip Expansion – 15-pin header with 3x GPIO, SPI, I2C, analog input, PWM or analog output, CAN bus […]

ESP32 UWB board features DW1000 module for accurate indoor positioning

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 […]
