Xilinx Zynq SoCs are probably the most well-known FPGAs with ARM cores, as their Cortex A9/A53 cores can run Linux, but they are not the only ones. Microsemi launched SmartFusion2 SoC comprised of FPGA fabric and an Arm Cortex-M3 core in 2013, as well as a $300 development kit. The company has now partnered with Digikey to launch SmartFusion2 Maker Board, a low-cost evaluation platform for the SoC that comes with Gigabit Ethernet, a USB port, a connector for ESP8266 module, PCB footprint for ESP32 module, among other features like a light sensor, LEDs, and buttons. SmartFusion2 maker board (M2S010-MKR-KIT) main features & specifications: SoC – Microsemi SmartFusion2 M2S010 SoC with: Arm Cortex-M3 @ 166 MHz, 6oKB+80KB eSRAM, 256KB eNVM FPGA with 12,084 logic element, 400 Kbits RAM Storage – 16 Mbit SPI Flash Connectivity Gigabit Ethernet via VSC8541 PHY, RJ45 connector Connector for ESP8266 (Sparkfun WRL-13678 – not included) […]
Year 2017 in Review, Top 10 Posts, and Some Fun Stats
2017 is coming to an end, and as I do every year, I’ll take a look back at the year that was on CNX Software. The pace of development boards launches has not slowed down this year, and we get an even wider range from the low-end with Orange Pi or NanoPi boards, to much more powerful ARM boards, and some new entrants like Libre Computer. The same is true for TV boxes, most of which now support 4K HDR, ranging from ultra cheap models selling for less than $20 to higher end Android TV boxes, while mini PCs were dominated by Intel Apollo Lake models, although some Cherry Trail products were also launched. Processor-wise, Amlogic launched more Amlogic S905X derivatives with S905W/S905D/S905Z, which are popular in the TV box market. Rockchip’s most interesting processor this year was RK3328 quad core Cortex A53 processor designed for 4K HDR Android TV […]
Obniz ESP32 Board is Programmable in JavaScript from the Cloud (Crowdfunding)
ESP32 WiFi / Bluetooth boards are now commonly supported by the Arduino IDE, and alternative firmwares are also available to program them using JavaScript (e.g. Espruino), or MicroPython. But if are familiar with JavaScript / Node.js, and don’t want to flash your own firmware, Obniz board could be an option. The board exposes 12 I/Os programmable from the company’s Cloud service, and features a OLED display used to show your program information, or a QR code to easily program the board from your smartphone’s browse once a WiFi connection has been setup. Obniz hardware specifications: Wireless Module – ESP-WROOM-ESP32 based on ESP32 dual core 802.11 b/n/g WiFi + Bluetooth LE WiSoC Display – 128×64 OLED display I/Os 12x I/O pins each configurable as GPIO, ADC, UART, SPI or I2C (no specialized pin, each can handle those functions) Up to 1A drive per I/O to control motors 3.3 or 5V selectable […]
ESP32-PICO-KIT v4 Board Based on ESP32-PICO-D4 SiP Now Available for $10
A little while ago, I received a bunch of ESP32 PICO Core development boards which were based on Espressif Systems ESP32-PICO-D4 system-in-package with ESP32, 4MB SPI Flash, and other components. The advantage of such chip is that is requires less external component, and allows for smaller designs. For example, the boards I received would leave two row of pin on each side of the board, while most other ESP32 boards will only expose one row on each side. I used the board to play with Micropython ESP32 port, and later-on when I launched a giveaway of 8 of the boards, I found out the name had changed to ESP32-PICO Kit, with the documentation listing v3 with all pins connected to male headers, and v4 with 6-pin not connected to a male header as shown in the photo below. Both versions of the board also have a different pin layout. But […]
A Day at Chiang Mai Maker Party 4.0
The Chiang Mai Maker Party 4.0 is now taking place until December 9, and I went there today, as I was especially interested in the scheduled NB-IoT talk and workshop to find out what was the status about LPWA in Thailand. But there are many other activities planned, and if you happen to be in Chiang Main in the next few days, you may want to check out the schedule on the event page or Facebook. I’m going to go though what I’ve done today to give you a better idea about the event, or even the maker movement in Thailand. Booth and activity area should be the same over the 4 days, but the talks, open activity, and workshop will be different each day. Today, people could learn how to solder in the activity area. The even was not really big with manufacturers/sellers like ThaiEasyElec, INEX, or Gravitech closer […]
Xiaomi Unveils Their Very Own ESP32 Development Board, Module & SDK
We now have plenty of modules and board based on Espressif System ESP32 dual core wireless SoC, and a fairly good software support with ESP IDF SDK, Arduino Core, MicroPython, Espruino and other solutions. So I was surprised when I saw Teo Swee Ann, Espressif CEO, posted photos about an event – Xiaomi IoT Developer Conference – where Xiaomi apparently introduced their own ESP32 development board, together their own SDK (still empty right now) compatible with the company’s Mijia ecosystem, as part of their “Open IoT platform” The slide below translates as “WIFI module – Automated manufacturing / 4-fold foolproof mechanism / whole process tracing / cost price (about 15 RMB)” and “Open source SDK”, with the price likely the price of Xiaomi ESP32 module (ESP-WROOM-32C) shown on board above (Thank to hm for translation). I could not find much information at this early stage, except new partnership between Baidu […]
Giveaway Week Winners – November 2017
Like every year, I’ve organized a giveaway week to send some of the items I’ve reviewed in the past year or so. There was a good mix of devices this year starting with a mini Linux NAS kit, following by some ESP32 boards, and Amlogic development boards among others. The results are in, and instead of 10 winners, I actually have 11 winners due a “timing issue”, and to make for one missing ESP32 board, a LinkIt Smart 7688 Duo board was also given away. While it started strongly for Eastern Europe, We have winners from 3 continents this year: NanoPi NEO2 NAS Kit – Hap Hapablap, Serbia Muses Beta DVB Encoder and Modulator Board – Luka, Slovenia ESP32 PICO Kit v3 boards (5 Winners): Andrius Kurtinaitis, Lithuania (2x ESP32 boards) Kebab, Turkey (2x ESP32 boards) Zoobab, Belgium (2x ESP32 boards) Sollie, Germany (2x ESP32 boards) BobR, USA (1x ESP32 […]
Giveaway Week – ESP32 PICO Kit v3 Boards
I don’t have one, but eight boards to give away to four winners (2 each) with Espressif Systems ESP32 PICO Kit v3 board based on ESP32-PICO-D4 SIP, an all-in one package with ESP32, 4MB SPI flash, crystal oscillator, and passive components, which allows for smaller boards. The board is very similar to any other ESP32 boards, and software compatible, but it’s just quite thinner, and easier to work with on breadboards. Since I had already played with Arduino Core and Espruino (JavaScript) on other boards, I used one of the 10 boards provided by Espressif to play with Micropyhon on ESP32. Each winner will get two ESP32 PICO Core board in order to make it worthwhile with regards to shipping costs. To enter the draw simply leave a comment below. Other rules are as follows: Only one entry per contest. I will filter out entries with the same IP and/or […]
