Espressif ESP32-PICO-KIT WiFi/WLAN+Bluetooth Module

ESP32-PICO-KIT V4 is a mini development board produced by Espressif. At the core of this board is the ESP32-PICO-D4, a System-in-Package (SIP) module with complete Wi-Fi and Bluetooth functionalities. Comparing to other ESP32 chips, the ESP32-PICO-D4 integrates several peripheral components in one single package, that otherwise would need to be installed separately. This includes a 40 MHz crystal oscillator, 4 MB flash, filter capacitors and RF matching links in. This greatly reduces quantity and costs of additional components, subsequent assembly and testing cost, as well as overall product complexity.

SensiBLEduino – A full fledge ‘hardware-ready’ development kit for IoT and supports Arduino

IoT which translates to the Internet of Things has been a significant buzz for the last five years while disrupting major Industries (from Agriculture, Energy, Healthy, Sports and several others).

SensiBLEduino
SensiBLEduino Development Kit

IoT adoption has seen rapid development in the makers’ world, with different makers and manufacturers producing various forms of boards, chips, software to facilitate quick IoT development. Boards like ESP8266 from Espressif System is used for rapid prototyping and a low-cost choice for Wi-Fi-based IoT applications. Israeli based IoT firm SensiEdge has launched the SensiBLEDuino, an off-the-shelf, hardware-ready development kit based on the open-source Arduino for rapid prototyping of IoT applications.

SensiBLE is a full fledge customizable solution for those wanting to design IoT products. It helps to fasten development with a variety of sensors onboard, along with Bluetooth LE 4.1 capabilities and a low-power ARM® 32-bit Cortex®-M4 CPU with FPU. Some of the main challenges when embarking on IoT product development are; what platform will I use? What sensors are available to achieve my goal(s)? How do I handle connectivity? What about the Cloud Platform to use, and so on. Developers or product designer always result in the use of several boards or modules to achieve this while also increasing the time to bring the product to life. The SensiBLE kit removes most of these fears; it combines hardware and software in tiny form factor to allow developers get their product to market quickly at lower development costs. (more…)

Odroid-N1 Features Gigabit Ethernet And Can Run Android 7.1, Ubuntu, Debian

The Rockchip RK3399 has revolutionized the open-spec single-board computer world. Hardkernel’s new Odroid project has made the multi-core SoC RK3399 to firm it’s grip further. Recently Hardkernel released images, specs, and extensive benchmarks on a prototype for its storage-oriented new Odroid-N1 board. The boards can be expected to launch for about $110 in May or June this year.

The 90x90x20mm SBC is highlighted for offering dual channel SATA III interfaces and 4GB DDR3-1866 dual-channel RAM. The Odroid-N1 can run Android 7.1, as well as Ubuntu 18.04 or Debian 9 with Linux Kernel 4.4 LTS. This new board can also be open source as its previous flagship Odroid-XU4.

The RK3399 features two Cortex-A72 cores that are clocked at up to 2.0GHz, as well as four Cortex-A53 cores, which are clocked at 1.5GHz. (Some other RK3399 boards have listed 1.42GHz.) This board also includes a high-end ARM Mali-T864 GPU. Hardkernel’s benchmarks have shown the hexa-core RK3399 based Odroid-N1 is running significantly faster on most tests, beating the Odroid-XU4’s octa-core (4x Cortex-A15, 4x -A7).

The Odroid-N1 is equipped with a GbE port, 2x USB 3.0 ports, and 2x USB 2.0 ports, HDMI 2.0 port for up to 4K Video output. There’s also a 40-pin GPIO header. The Power input is mentioned at 12V/2A, although attaching two 3.5inch HDD will require a 12V/4A PSU. As with the other RK3399 boards, there are no hopes of Raspberry Pi add-on compatibility.

The RK3399 has powered many similar SBCs previously. The first major RK3399 SBC was Firefly’s Firefly-RK3399, soon followed by Vamrs’ similarly open source Rockchip RK3399 Sapphire. More recently we’ve seen Shenzhen Xunlong’s Orange Pi RK3399.

The RK3399 is also finding key roles among many commercial boards. We just saw Aaeon take the leap with its OEM-oriented RICO-3399 PICO-ITX SBC. Earlier, Videostrong announced a VS-RD-RK3399 SBC.

ODROID-N1 key features:

  • Rockchip AArch64 RK3399 Hexa-core processor
  • Dual-core ARM Cortex-A72 2Ghz processor and Quad-core ARM Cortex-A53 1.5Ghz processor, big-LITTLE architecture
  • Mali-T860MP4 GPU, support OpenGL ES1.1/2.0/3.0, OpenCL 1.2
  • 4Gbyte DDR3-1866 RAM, Dual channel interface for 64bit data bus width
  • 2 x SATA3 port, native SATA implementation via PCIe-gen2 to SATA3 interface
  • eMMC 5.0 (HS400) Flash storage and a UHS capable micro-SD slot.
  • 2 x USB 3.0 host port
  • 2 x USB 2.0 host port.
  • Gigabit Ethernet port
  • HDMI 2.0 for 4K display
  • 40-Pin GPIO port
  • OS: Ubuntu 18.04 or Debian Stretch with Kernel 4.4 LTS, Android 7.1
  • Size: 90 x 90 x 20 mm approx. (excluding cooler)
  • Power: 12V/2A input (Attaching two 3.5inch HDD requires a 12V/4A PSU)
  • Price: US$110 (To be adjusted based on DRAM market price changes)
  • Mass production schedule: TBD

Simple Arduino Data Logger

Schematics

A data logger is an electronic device or instrument that records data over a period of time. It allows the user to record time or location stamped data which can be viewed at a later time or real time.

Irrespective of the type of data being logged or the kind of data logger, these devices usually contain two main units, the sensor unit and the storage/communication unit. The sensor unit may involve the use of an external instrument or a sensor embedded within the device. Increasingly, but not entirely, data logging devices are becoming more based on micro processors and microcontrollers, which has opened up a whole new level of data gathering and storage.

Bosch BMA400 – Did you thought accelerometers couldn’t get any better?

Accelerometers are used in almost all fields, and they have been growing in popularity in IoT and wearables. Nowadays, those devices require a of energy, and because of this, they need to be constantly charged or batteries need to be constantly changed which causes users to lose interest, or to be limited by this problem. Size might be a problem too because some MEMs (micromechanical systems) acceleration sensors are too big to be implemented in everyday portable objects. In June 2018, Bosch will unveil their BMA400, a sensor that extends battery life and has a huge range of capabilities in a small size.

BMA400 is capable of measuring tilt, orientation, tap/double tap, and step counting (with activity recognition) using a low- noise measurement of accelerations in three perpendicular axes. Additionally, the device only uses 10% of the energy current comparable devices use which makes it useful for applications where charging is impossible. For example, this device could be used for package tracking over long distances, saving power by putting itself on sleep mode until something happens (the package is mishandled) which could compromise the quality of the product inside the package.

Other applications include home automation (automatic air conditioning that considers status (open or closed) of windows and doors), security (burglar detection), and sports. The BMA400 includes an activity detection function that can differentiate between walking, running, and standing. All this could be applied into wearables, and because of its size it could be a game changer in hybrid smartwatches (traditional watch with added smarts in a discrete way).

BMA400 measure only 2 mm x 2 mm x 0.95 mm, and device data can be retrieved over longer intervals (FIFO buffer of 1kB). Other specifications include:

  • 12-bit digital resolution
  • Output data rate (ODR) of 12.5 Hz to 800 Hz
  • Supply voltage of 1.71 V up to 3.6 V

Complete list of specifications can be found in the official website.

This improvements in an already widely used technology could result in advances in thousands of different devices, and in the implementation of this sensor in devices where it couldn’t be fitted before. Improving battery means improving product usability which results in happy users who can now use their device for longer periods of time. Also, makers and hobbyists could now apply this technology to new devices using the increased battery life as an advantage.
