ODROID-N1 Canceled due to RAM Supply Issues, ODROID-N2 Coming Later this Year

ODROID N1 Cancelled

Rockchip RK3399 powered by ODROID-N1 board was unveiled earlier this year with two SATA interfaces, up to 4GB RAM, HDMI 2.0 4K UHD output, Gigabit Ethernet,  and more. The plan was to launch the board in May or June for around $100. Sadly, the board has been canceled for reasons we’ll explain below, but the silver lining is that a more powerful ODROID-N2 should become available by the end of the year. The reason for the cancellation is all explained in a forum post in ODROID forums: After announcing the N1 board in February, we started to prepare all the components for the mass production. But Samsung and Hynix suddenly informed us 1GB DDR3 chip was End-of-Life phase and we couldn’t place any order. It meant we could not make 4GB model since there must be four DRAM chips mounted on the board. We could make a 2GB model only with four 512MB DDR3 chips. But it couldn’t make any …

SIM7020E 4G NB-IoT Mini Development Board Sells for Just $14

Cheap-NB-IoT-Board

We now have plenty to choose from when it comes to NB-IoT development boards or shields, but so far pricing has not been very attractive, and the cheapest NB-IoT solution I found so far was probably Dragino NB-IoT Bee, a XBee compatible board going for $23. But this morning, I saw an even cheaper NB-IoT board with SIM7020E 4G NB-IOT Mini development board selling for $14.30 on Electrodragon. Not quite the price of 2G solutions, but we’re getting there. Board specifications: NB-IoT Module – SIMCom SIM7020E module working globally with B1/B3/B5/B8/B20/B28 bands supported Nano SIM card holder and u.FL connector for NB-IoT Expansion – 9-pin unpopulated 2.54mm pitch header with 2x UART (3.3V / 5V), ADC, Boot, 3.3V, 5V and GND USB – 1x micro USB port that can be recognized by PC, but as Electrodragon puts it: “not sure how to use it”. Misc – Net LED, power key Power Supply – 5V via header (or micro USB port?); …

Xilinx Zynq-7020 based PYNQ-Z1 Arm + FPGA Board is Meant to be Programmed with Python

PYNQ Z1

Xilinx Zynq-7000 series is a family of SoC based on Arm Cortex A9 processor coupled with FPGA fabric, and since the introduction in 2012, we’ve seen may board based on the entry-level Zynq-7010 or Zynq-7020 SoCs. Digilent PYNQ-Z1 is another Xilinx Zynq board from the company, but it does not differentiate itself by its hardware features, and instead the software part is the most interesting. The board is designed to be used with PYNQ, a new open-source framework that enables embedded programmers to exploit the capabilities of Xilinx Zynq SoCs without having to design programmable logic circuits, relying instead on Python programming. Digilent PYNQ-Z1 hardware specifications: SoC – Xilinx Zynq-7020 (XC7Z020-1CLG400C) dual core Arm Cortex-A9 processor with FPGA with 1.3 M reconfigurable gates System Memory – 512MB DDR3 Storage – Micro SD card slot, 16MB QSPI Flash with factory programmed globally unique identifier (48-bit EUI-48/64 compatible).

Wemos LOLIN D32 Pro ESP32 Board Supports TFT Displays, Comes with a micro SD Card Slot

Wemos LOLIN D32 Pro

Wemos is popular for their low cost WiFi board based on Espressif SoCs. Their most popular board is ESP8266 based Wemos D1 mini  thanks to its compact form factor, low price ($5 shipped), and available add-on boards. But they’ve also launched some ESP32 in the last year or so with development boards such as Wemos LOLIN32 Lite. Their latest ESP32 board – LOLIN D32 Pro v2.00 – features ESP32-WROVER module, and beside exposing I/Os via breadboard compatible headers, also offers a micro SD card slot, a TFT display connector, and an I2C header.

Hikey 970 Documentation, HiAI DDK, Linux Firmware Images, and Support Forums

Hikey 970 board has impressive specifications with Huawei Kirin 970 SoC featuring an octa-core Arm Cortex A73/A53 processor and an Arm Mali-G72-MP12 GPU, coupled with 6GB LPDDR4x and 64GB UFS storage. It’s also one of the first broadly available developer platforms equipped with a Neural Processing Unit for artificial intelligence applications. However when it launched in April, Hikey 970 documentation was lacking, and despite the board is supposed to run both Android (AOSP) and Linux distributions such as Ubuntu or Debian, so far only AOSP is shown in the download section, with Linux distributions “coming soon”. But if you want to start as soon as possible there are still some good news. First, some documentation for the board has been released on Github, including getting started guides, hardware documentation (schematics, user manual, etc..), and some instructions to build AOSP from source code, and flash it to the UFS storage. If you are interested in Huawei artificial intelligence SDK (HiAI DDK) …
