Get an Early ESP32 Board by Contributing to Luanode for ESP8266 & ESP32 Project (Crowdfunding)

June 22nd, 2016 4 comments

Development boards and module based on Espressif ESP32 dual core processor with WiFi and Bluetooth LE connectivity are due for Q3 or Q4 2016, but you could get an early sample as early as July if you contribute to Jimmy Wu’s (of crowdfunding campaign to develop Luanode (Lua SDK) for ESP8266 and ESP32 processors, as ESP32 boards are part of the rewards.


Luanode is a Lua SDK for ESP32 and ESP8266 that supports multi-tasking through FreeRTOS, and includes support for peripherals. The source code and documentation can be already be found on Github, and the main differences against something like NodeMCU appear to be multi-tasking and (for now) ESP32 support. Interestingly the SDK contains a tools called WiFi-Killer uses for Denial of Service (DoS) attacks using ESP8266 or ESP32 modules…


One hardware project is called WiFi tank comprised of one T300 Tank Chassis, ESP8266 Development Kit, 720p HD Camera, WR703N Wireless Router, and controlled by an Android or iOS smartphone. The company behind the project is DOIT (Doctors of Intelligence and Technology) and the funds would be used for hardware, software, and documentation.

With less than 3 days to go, the campaign has not reached its goal yet however. ESP32 development kit rewards is $19, while a pack with 6 ESP32 devkit only costs $39 (maybe baseboard + 6 modules?), and the WiFi tank “video car” is also offered for $219. Shipping appears to be included, and delivery is scheduled for July 2016 for all three rewards.

Thanks to Harley for the tip.

NXP Unveils i.MX 8 Multisensory Enablement Kit with Hexa Core ARMv8 Processor

May 17th, 2016 8 comments

Freescale, now NXP, i.MX 8 processors have been a long time coming, but finally the company has now unveiled a Multisensory Enablement Kit based on i.MX 8 hexa core ARMv8 processor combined with a Vulkan-ready & OpenCL capable GPU.

i.MX8_Multisensory_Enablement_KitKey features of the development kit:

  • Multisensory Processor Board
  • Multisensory Expansion Board
  • Isolation and separation of secure, safe and open domains
  • Rich compute (6x ARMv8 64-bit main CPUs, OpenCL GPU)
  • Vulkan-ready GPU with HW tessellation and geometry shading
  • Efficient, multi-screen (4x) support via HW virtualization
  • Failover-ready display path
  • Up to 8x camera input for 360 degree vision
  • Integrated vision processing
  • HDR enhanced video
  • Multi-sensor fusion and expansion
  • Multi-core audio and speech processing
  • NXP radio solution integration

However, at the time of writing, there’s very little information about i.MX8 processors themselves, but I’m confident much more info should soon surface as NXP FTF 2016 is taking place now until May 19, 2016. The press release about i.MX8 MEK does mention 4K video and graphics, and some security features. The company expects the processor to be used for for intuitive gesture control, voice recognition, natural speech recognition and audio acceleration, as well as healthcare and industrial applications such as connected vehicles.

NXP i.MX 8 MEK is said to be available now, together with the BSPs and middleware. More details should eventually be posted on i.MX8 MEK page.

[Update: I found a slide about i.MX8 with some details. Source: NXP Forums.

“BluePill” is a $2 Arduino Compatible Development Board Based on STMicro STM32 MCU

May 17th, 2016 35 comments

I’m amazed that if your budget for a board was just $5 for one MCU board, you now have so many options for your electronics projects: ESP8266 boards, a few STM8 boards, One Dollar Board project, and many more… Other options are “BluePill” or “RedPill” boards based on STM32 or GD32 32-bit ARM Cortex M3 micro-controllers that go for about $2 shipped, and can be programmed with the Arduino IDE thanks to STM32Duino project.


BluePill board specifications:

  • MCU – STMicro STM32F103C8T6 ARM Cortex-M3 MCU @ 72 MHz with 64KB flash memory, 20KB SRAM.
  • USB – 1x micro USB port for power and programming
  • Debugging – 4x pin SWD header or micro USB port
  • Expansion – 2x 20-pin with power signals, I2C, SPI, GPIOs, ADC inputs, etc…
  • Misc – Reset button, two jumpers (for boot mode), power and user LEDs.
  • Power – 5V via USB, 2.0-3.6V power via 3.3V pin on SWD header.
  • Dimensions – 5.3cm x 2.2cm.

I specifically wrote about “BluePill” board instead of “RedPill”, because one thread on STM32duino forums mention the former is a bit better. You can find documentation on wiki (Italian only) and STM32duino wiki. Most instructions use a USB to serial (TTL) board to program connected to PA9 and PA10 pins to program the board, but I understand that USB programming if possible by replacing the 10kΩ pull up resistor on PA12 (USB D+) by a 1.5kΩ resistor.

The video below shows how to use the STM32 board with a serial debug board, and the Arduino IDE.

One interesting fact about the $2 price tag for the board (remember it also includes shipping) is that STM32F103C8T6 MCU itself is supposed to sell for $2.056 in 10k quantities, until you are looking for actual pricing in China, where it is sold for less than one dollar (6 RMB).

Beside Aliexpress, you can also find the board on eBay. Few sellers call it BluePill, and instead they are often called “STM32 Minimum System Development Board”, but a search for “STM32F103C8T6″ on your favorite resellers should also list the board.

Thank you Zoobab!

Getting Started with Wio Link Starter Kit, Visual Programming Android App, and IFTTT

May 15th, 2016 1 comment

Wio Link is a board based on on ESP8266 WiSoC that supposed to be easy to setup thanks to Grove modules – no breadboard and mesh or wires – and, as I first understood it, to program thanks to a drag and drop mobile app that does not require any actual programming. More advanced users can also use a RESTful API in Python, JavaScript, Node.js, PHP, Objective-C or Java. I’ve been sent a $49 Wio Link Starter Kit including the board, a USB cable, and six Grove modules to evaluate the kit. I’ll start by have a look a the kit, before experimenting with Wio Link Android app.

Wio Link Starter Kit Unboxing

The kit is sent in a red plastic case.

Wio Link board is lodged in the top covers, and other accessories placed in bags in the main part of the case.

Click to Enlarge

Let’s check the board first.

Click to Enlarge

Click to Enlarge

There are three main ICs: ESP8266EX WiFi SoC, Silabs CP2102 USB to TTL chip for programming the board, and Winbond 25Q23BVIG serial flash memory (4MB). On the right side, the micro USB port is used for power and debugging, a header can be used for battery power, and Config and Reset buttons are present. The six Grove connectors can either take digital (3) modules, analog (1) modules, I2C (1) modules, or UART (1) modules.

The bottom side of the board does not any components, and the only noticeable parts are Seed Studio and Open Source Hardware logo, as well as which point to documentation and forums for the board.

Once I’ve taken everything out of the small bags, we can see the fully kit content with Wio Link board, a micro USB port, and from top left to bottom right, six Grove modules and their cables: WS2812 LED strip (25 LEDs), temperature and humidity sensor, button, digital light sensor, 3-axis digital accelerometer, and a relay module.

Grove_Module_MarkingsIf you have many Grove module, it may not always be easy to know which one does what, but the Grove module is printed on the silkscreen on the back the board.

Wio Link Android App

Wio / Wio Link app is available for both Android 4.1+ and iOS 7+, and I tested the board with the Android app, following some of the instructions on the Getting Started Guide.

Click to Enlarge

Click to Enlarge

The first step is to login or create an account with your email, before setting up Wio Link, or the small and soon-to-be released Wio Node.

Click to Enlarge

Click to Enlarge

At this stage, I had to power Wio Link board. I did so by connecting Wio Link to one of the port my USB hub, and I noticed the red LED would blink very fast, but pressing on the Config button as instructed in the app would not do anything, and Wio Link was not detected at all. So I changed to a proper 5V/2A power supply, and the red LED was steady, with the green LED in the middle of the board slowly blinking, and after pressing the Config button for about 4 seconds, the blue TURN lit up. So if the board does not work, try another power supply. The USB cable should be OK, as it’s shipped with the board.

After that you can select Wio (WioLink_XXXXXX), select an access point (AP) to connect the board to the Internet, and give your board a name – I went with cnxwio – to complete the setup.

Click to Enlarge

Click to Enlarge

Then you can select module on the bottom, the app will show you where you can drag and drop it (Digital. Analog, UART, or I2C), and then repeat the same process with the other modules.  I had the idea of making a demo reporting the temperature and humidity, while turning off the LED strip with the accelerometer, and turning it on with the button module, so I connected the four modules in the app and in “real life”.


Once you are happy with the setup, tap on Update to flash the firmware to the board. This should take a few seconds. At this stage I was expecting to be able to do some more visual programming, but all you can do is tap on API to get the API info, and experiment with the API. So rather than a complete programming solution, Wio app is an help for program development.

Click to Enlarge

Click to Enlarge

The three screenshots above show the list of Wio Link boards and their connected modules, and one API call to control the LED strip, namely to make it “blink in a rainbow flow”. You can also share the API by email or other method to get the API calls on your computer and get on with programming. This is the list of API calls I got with the four modules. You can simply use the command link in a Linux computer (or now Windows Subsystem for Linux) to monitor and control the board with curl. You can also use Python or other programming languages to use the API, as show in that controls a traffic light.

But for the purpose of this review, I did not want to write code, only use graphical tools or app, so my next option was IF by IFTTT app.


Right after  you start the app, tap on the top right icon to Browse recipes, select “Create a New Recipe“, tap on “+”  (Start Here!) icon, and search for Seeed trigger. The first time you’ll be redirected to login to Seeed Studio – which the password created at the beginning of this tutorial – in your browser, and once it’s done you’ll be able to “Monitor a sensor value”, select one action related to the sensors connected to Wio Link, and complete the trigger. I wanted to detect when the button is pressed (The value should be 0 when pressed) on the Grove module. There’s a big caveat doing this, but more on that later.

Click to Enlarge

Click to Enlarge

Now click Next to select the “That” step, and again search for Seeed to select one of the “Actions”, and configure it. I wanted to turn on the LED strip, and selected “light up Grove WS2812 LED strip” and “Random Rainbow”, before pressing on Finish to complete the action.

Click to Enlarge

Click to Enlarge

That’s all good, except for one detail. It did not work, as pressing the button had not effect. After configuring the accelerometer to turn off the LED strip, I started to receive notifications every 2 to 5 minutes about the “shaked” status. So I went to recipe, modified it to turn on the LED when the accelerometer is shaken, and press the Check Now button to verify it, and the LED strip indeed lit up. So unless I’ve somehow missed an important option, that meant IFTTT is not suitable for my use case, because everything is handled from the cloud, and it’s not “polling” the sensors quite often enough.  However, If you want to monitor the temperature sensor, and take an action if the temperature rise above a threshold, that’s perfectly usable as long as it can be taken within a few minutes.

Click to Enlarge

Click to Enlarge

As one last experiment, I set the LED strip to turn on each time I receive a new email in my gmail account. It did not work for the first email, even after waiting a few minutes (5+ minutes), and then pressing “Check Now”. So I sent another email, waited one or two minutes without results, and pressed “Check Now” again, and the LED strip finally turned on.

So the takeaway is that Wio Link app does make setting up the board easier, and also provide an easy to use reference to the API after the configuration, but it’s not a pure visual programming app per se, and you’ll need to write your own program using the RESTful API. Alternatively IFTTT app can be used to control the board using triggers from the Internet (Facebook, twitter, emails, ….) or sensors from the Grove module, and the app then take actions using the Grove modules such as relays or LED strips, but there are some limitations to what can be done, and my experience with IFTTT and Wio Link was mixed.

I’d like to thank Seeed Studio for sending Wio Link Starter Kit for evaluation. You can purchase the kit for $49 on Seeed Studio if you are interested.
