RushUp KITRA Board Family is based on Samsung Artik 020, Artik 520/530, or Artik 710 Modules

Samsung first announced their Artik IoT modules almost three years ago, and until recently most Artik related products or development kits came from Samsung themselves, with no third party involved. But this has started to change recently with announcements such a Seeed Studio Eagleye 530s low cost development board based on Artik 530 module, and Resin.io Project Fin combining RPI CM3L module with an Artik 020 module for low power Bluetooth connectivity. But as I flicked through Resin.io supported hardware, I discovered they also supported Linux powered Artik 520 and Artik1020 module, as well as some new “KITRA” boards I had never heard of, and if we visit RushUp company website, we can see they have a bunch of Kutra boards and one IoT gateway based on Artik modules: KITRA 520 – Samsung ARTIK 520 product accelerator for advanced IoT KITRA 710 – Samsung ARTIK 710 product accelerator for advanced multimedia […]

Rigado Vesta IoT Gateway Runs Linux and Zephyr OS, Supports Bluetooth 5, 802.15.4, WiFi, Ethernet and Cellular Connectivity

I’ve recently read several open source software news related to Rigado IoT gateway, starting with Canonical announcement last month, that the gateway would ship with Ubuntu Core starting in summer 2018, and a few days ago it popped up again during Linaro CEO keynote at Linaro Connect HK 2018, as one of the first commercial devices to run the Zephyr OS, specifically its fully open source Bluetooth stack on a Nordic nRF52 chip. Rigado Vesta IoT gateway is not exactly new, as it was first announced in December 2016. The hardware relies on an NXP i.MX 6UL Cortex A7 processor, up to 256MB RAM, 4GB eMMC flash, and includes built-in support for dual band WiFi, Bluetooth Smart, Bluetooth 5/4.2, 802.15.4 (Thread), Fast Ethernet with PoE, as well as optional support for a cellular LTE Cat 1 modem. Rigado gateway hardware specifications: Processor – NXP i.MX6 UltraLite (G3) Arm Cortex A7 […]

ESP32-WROOM-32D / ESP32-WROOM-32U WiFi & Bluetooth Modules Deliver Better RF Performance

ESP-WROOM-32 is likely the most popular ESP32 WiFi + Bluetooth module on the market, but a few months ago, Espressif Systems unveiled two variants named ESP32-WROOM-32D / ESP32-WROOM-32U, which are based on ESP32-D0WD (5x5mm package) instead of ESP32-D0WDQ6 (6x6mm package), and are said to offer better RF performance ESP32-WROOM-32D is the most similar to ESP-WROOM-32 since it also comes with a PCB antenna, while ESP32-WROOM-32U is much smaller as it relies on an external WiFi/Bluetooth antenna via a u.FL connector. Both new modules are pin-to-pin compatible with ESP-WROOM-32 Key features: CPU – Espressif ESP32-D0WD dual core Tensilica processor Storage – 32Mbit SPI flash Crystal – 40 MHz Connectivity – Wi-Fi 802.11 b/g/n up to 150 Mbps, Bluetooth 4.2 LE I/Os – 38- catellagated pin with I/Os + GND plane Antenna ESP32-WROOM-32D – on-board antenna ESP32-WROOM-32U – u.FL connector for external IPEX antenna Dimensions ESP32-WROOM-32D – 18 x 25.5 x 3.1 […]

ALB32-WROVER is an ESP-WROOM-32 Compatible Module with 32 Mbit PSRAM, up to 128 Mbit Flash

ESP-WROOM-32 is one of the most commonly ESP32 WiFi + Bluetooth module, and does the job for many applications. However, it only includes 4MB (32Mbit) flash, and no external PSRAM, while Espressif ESP32 chip itself supports up to 128 Mbit (16MB) NOR flash and up to 32Mbit (4MB) PSRAM, so for applications demanding more resources (e.g. MicroPython), or for initial development it would good to have a module maxing out memory and storage capabilities of the chip. Analog Lamb ALB32-WROVER does exactly that with 32 Mbit PSRAM, and 32 to 128 Mbit flash, in a form factor compatible with ESP-WROOM-32 module. ALB32-WROVER specifications: WiSoC – Espressif ESP32 (Rev0?) Wi-Fi and Bluetooth combo chip External Memory – 32Mb PSRAM Storage – 32, 64, or 128Mbit Flash Dimensions – 18 x 25 x 3 mm Compatible with ESP-WROOM-32, except for GPIO16 & 17 (used for PSRAM) It’s very odd the company claims the […]

Eagleye 530s Board Features Samsung Artik 530s IoT Module, Leverages Raspberry Pi Form Factor

Samsung Artik 530 is a module designed for the Internet of Things based on a quad core Arm Cortex A9 processor, and supporting Ethernet, dual band WiFi, Bluetooth 4.2, and 802.15.4/Zigbee/Thread connectivity, as well as exposing display and camera interfaces, and of course various I/Os. The module was launched about one year ago with a developer kit that cost $189 and up, but Samsung has now worked with Seeed Studio to launch a cheaper developer board – called Eagleye – based on the secure version of the module (Artik 530s) and mostly following Raspberry Pi form factor in order to take advantage of its hardware ecosystem. Eagleye 530s board specifications: SoC – Unnamed quad core Arm Cortex A9 processor @ 1.2GHz with 3D graphics accelerator System Memory – 1GB DDR3 Storage – 4GB eMMC flash, SD card slot Connectivity 802.11a/b/g/n dual band SISO (2.4G/5G) Bluetooth 4.2(BLE+Classic) Zigbee/Thread 802.15.4 Gigabit Ethernet […]

Particle Unveils Three nRF52840 Bluetooth 5 Boards: Argon (WiFi), Boron (LTE), and Xenon, as well as Particle Mesh Technology

In the last year or so, Bluetooth has gotten an upgrade with the release of Bluetooth 5. The new protocol works on several existing platforms, but if you want support for the full set of Bluetooth 5 features such as longer range and higher bandwidth, we’ve seen you need a recent chip such as Nordic Semi nRF52840. However so far, AFAIK you had to buy Nordic Semi own development kit for play with nRF52840, and now Particle has announced not one, but three low cost development boards powered by nRF52840 chip starting at just $9, and supporting their newly announced Particle Mesh technology. So for some reasons, it appears they did not go with Bluetooth Mesh. Particle Xenon – Bluetooth 5 + Mesh Xenon is the cheapest model with the following specifications: SoC – Nordic Semiconductor nRF52840 Arm Cortex-M4F 32-bit processor @ 64MHz with 1MB flash, 256KB RAM Storage – […]
