Making your own drone with GNSS click
Posted by Lana Vulic on 27 March 2017 01:53 PM

A project on hackster.io uses GNSS click to build a semi-autonomous drone. The click plays its part as a GPS receiver.

Read the whole tutorial to see the necessary code, GPS and IMU sensors wiring and more.

The next installment of this tutorial will teach you how to add motor control to the device so that the drone can take flight and fulfill its purpose.

You can start with the video, to see the half-done drone in action. Don’t expect to see it flying yet, it still needs a motor. But what you can see is GNSS click locating the device on google maps.

Better coverage with both GPS and GLONASS satellites

GPS, GLONASS, and Galileo are the three main parts of the GNSS system. At any time there are six to twelve satellites above the horizon that can be used to calculate a position. A GNSS receiver needs at least four satellites to get the necessary information: latitude, longitude, and altitude. The simple conclusion being that the more satellites there are, the more accurate the results will be.

The latest GPS satellite in orbit weighs around 1,400kg. That is the weight of an average midsized car. Imagine a Toyota Prius moving through space, at the speed of several kilometers per second.

GNSS click

GNSS click carries the L86 module from Quectel, with an integrated patch antenna. It has a UART interface and runs on a 3.3V power supply.

With its ultra low power consumption of 20mA in tracking mode, it fits the IoT field like a glove.

For more information on the GNSS click, see the product page.

You can also take a look at the GSM/GNSS 2 click if you want to add mobile connectivity to your project as well.

Yours Sincerely,

Hexiwear Docking station bootloader update
Posted by Srdjan Misic on 24 March 2017 04:53 PM

As Hexiwear is getting mature as a product we are getting more feedback and opportunities to improve it. This time we addressed a marginal scenario: if you plug your Hexiwear into the Docking Station after erasing or corrupting the memory contents of the internal MK64 or MKW40 MCU, the Docking Station’s onboard programmer will automatically go into maintenance mode, preventing you from programming the blank Hexiwear.

There is a workaround to circumvent the maintenance mode. It mostly consists of following a prescribed sequence of manipulating the switches on the Docking Station. We posted detailed guidelines in the troubleshooting section in the Docking station’s Docs page.

Note that this problem will only affect users who have previously bought the Docking Station. As soon as we discovered the issue, we corrected the Docking Station’s bootloader firmware. Future customers will not have to resort to this workaround.

Also applicable to people who already own the Docking station, if you have an external programmer you will be able to burn the new version of the bootloader which we published on Github (make sure to follow the instructions in the readme file).

Again, this issue only occurs if you somehow corrupt or erase the memory contents from Hexiwear’s MK64 or MKW40 MCUs. Otherwise, there is nothing to worry about.

Yours sincerely,
MikroElektronika

GSM/GNSS 2 click — asset tracking, mobile communication and more
Posted by Lana Vulic on 24 March 2017 04:50 PM

The two-month climbing season for Mount Everest starts in late March. Why would you want to know this? Well, the Nepalese government is having a trial experiment and issuing GPS tracking devices to climbers this year.

For the first time in history, there will be bullet-proof evidence that someone has actually climbed the Everest. If you plan to climb the world’s tallest mountain, you can take our new click with you – GSM/GNSS 2 click – maybe it will be more accurate than Nepal’s GPS tracking devices.

GSM/GNSS 2 click

GSM/GNSS 2 click carries SIM868 quad-band GSM/GPRS module. SIM868 is integrated with a high-performance GSM/GPRS engine and a GNSS engine.

The module is designed with power saving technique so that the current consumption is as low as 0.65mA in sleep mode.

For more information about the click see the product page.

Yours Sincerely,
MikroElektronika

GainAMP click — dual channel gain amplifier
Posted by Lana Vulic on 23 March 2017 03:08 PM

Life is full of mysteries, but there is nothing mysterious about an amplifier. It takes an incoming voltage signal and makes that voltage bigger. Amplifiers boost radio signals, power giant speakers at rock concerts, or your favorite pair of headphones.

The newest click board™ we have out is an amplifier as well – GainAMP click.

GainAMP click

GainAMP click carries the LTC®6912 dual channel, low noise, digitally programmable gain amplifier.

The gains for both channels are independently programmable, using a 3-wire SPI interface to select voltage gains of 0, 1, 2, 5, 10, 20, 50, and 100V/V.

For more information about the GainAMP click see the product page.

Yours Sincerely,

Hexiwear WiFi and 3G examples released
Posted by Srdjan Misic on 21 March 2017 05:06 PM

Almost on this exact day last year the Hexiwear Kickstarter campaign reached the 35.000 funding mark. This triggered a stretch goal — creating WiFi examples for Hexiwear and the docking station, to enable users to stream sensor data directly to the WolkSense cloud without a BLE-enabled smartphone working as a gateway.

Admittedly, we stretched the meaning of the word “stretch” in stretch goal. It took us a year to deliver the promised example. But as a consolation prize, we are offering a double-treat: we also released an example that let’s you stream Hexiwear sensor data through the WolkSense cloud using a 3G connection.

The WiFi demo uses Wifi 3 click with the popular ESP8266 module, while the 3G demo uses 3G SARA click with a u-blox module.

In its current version, the examples are available as mikroC PRO for ARM projects. Setting them up requires some edits to the source code (instructions available in the readme file; among other things, it requires you to install a custom version of mikroC available on GitHub).

That said, we also plan to release a version where you can configure the settings from within the application. That way, a precompiled hex file would be all you need.

This example is a collaboration of MikroElektronika and WolkAbout. The project files are available on GitHub.

Sincerely yours,
MikroElektronika
