MOD-GPS back in stock, now with new chipset, support both GPS and GLONASS, better sensitivity, better price

mod-gps1

MOD-GPS is back in stock and got better. Now uses Ublox 7 chipset with 56 channel receiver, better sensitivity -162dBm, better voltage operation 2.7-5.0V. Less power consumption 38 mA typical and beside GPS it now supports also GLONASS standard.

comes with same magnet type antenna:

mod-gps2

and now you can safely connect it to OLIMEXINO-328 (Arduino 5V board)!

New Product in stock: A10-OLinuXino-LIME-UEXT adapter

Image

A10-OLinuXino-LIME-UEXT is adapter board with Male connector on 0.05″ which can connect to A10-OLinuXino-LIME GPIOs with  0.05″ step ribbon CABLE-40-40-10CM and allow LIME GPIOs to be used with BREADBOARD-1, or with A13-LCD43TS, A13-LCD7TS or A13-LCD10TS.

For the moment A20-LCD15.6 is not supported as LVDS signals got noisy when pass through A10-OLinuXino-LIME-UEXT but we are looking for solution.

UEXT signals can be used only when connected to GPIO1. On the other connectors UEXT signals will be not present.

New Product in stock: MOD-MPU6050 Digital 3-axis accelerometer + 3-axis gyro with UEXT

Image

MOD-MPU6050 is new Open Source Digital 3-axis accelerometer and 3-axis gyro combo breakboard. It comes with UEXT connector and cable so you can connect it to any of our development boards which have UEXT connector, but if you want you can use it also with breadboard as all MPU6050 signals are available in two rows at 0.1″ step on the two sides of the PCB.

The board is in stock and cost EUR 9.95

Demo code for OLinuXino in C and Python and for Arduino, MAPLE, Pinguino will be available on our web, the Eagle CAD files and schematic is also there.

New PIC-WEB firmware allow UEXT modules access over the web

Image

PIC-WEB with Microchip’s TCP-IP stack allow development of easy applications for the web. The best thing is that you don’t have to be PIC programmer nor to know C, you can make all your project in html, java script, ajax and you have all PIC resources as dynamic variables so you can toggle GPIOs and read ADC values etc in your html code.

We decided to extend this as PIC-WEB have UEXT connector, now you can access UEXT modules in the same convenient way, as Stanimir developed I2C and UART interface in the Microchip TCP-IP stack.

As you can see from the picture below:

Image

in the web resources you have I2C interface and thus you can send I2C commands to MOD-IO for instance over the web and drive relays ON and OFF, also read I2C sensors attached to UEXT connector.

The same resources for UART are also implemented:

Image

and this way you can interface MOD-LCD4.3 over the internet:

Image

for instance this happens when you send Clear command to the LCD over the web:

Image

so with the new firmware you can have access to all UEXT module resources: relays, sensors, LCDs etc.

Friday Free Board Quiz issue #25 is RPI-UEXT + MOD-IO2

Image

Image

RPI-UEXT allow Raspberry Pi to have access to different modules see original blog post we made about it: https://olimex.wordpress.com/2012/11/21/raspberry-pi-gpio-to-breadboard-and-uext-adapter/

MOD-IO2 allow RaspberryPi to control 2 relays and to read/write 7 additional GPIOs, including Analog inputs. On top of this MOD-IO2 is stackable and addressable so you can stack and connect to Raspberry Pi as many relays as you need for your project.

You have chance to win RPI-UEXT + CABLE26-pin + MOD-IO2 today if you answer correctly our quiz question!

Today at 17.00 o’clock our local Bulgarian time (GMT+2) we will post on Twitter our questions.

You have one hour to reply to our tweet with the correct answer.

At 18.00 o’clock we will count the correct answers and ask random.org to generate random number in range then announce the winner and ship the board by airmail in Monday.

Good Luck!

STELLARIS-UEXT adapter for Stellaris launch pad in stock

Image

STELLARIS-UEXT is Texas Instruments Stellaris Launchpad to UEXT adapter.

We have prepared demo code for MOD-GSM, MOD-MP3, MOD-GPS, MOD-TC, MOD-SMB380, MOD-IRDA, MOD-LCD3310 so you can interface these modules from your Stellaris Launchpad.

As Stellaris MCU have two SPI, I2C and UARTs we made the adapter with two separate UEXT connectors so you can connect two independant UEXT modules to it. Each UEXT have power up/down control with MOSFET so you can power up and down UEXT modules connected.

Raspberry Pi GPIO to Breadboard and UEXT adapter

Image

Raspberry Pi is the most successful embedded Linux board for all times, according to their blog they have sold over 500 000 pcs, although when they post something on their blog you never know it’s true or not from our own source we know Farnell and RS Components have sold at least 100 000 each by August this year, so the number may be not exactly 500 000 but still in 6-digit range.

I will admit that our OLinuXino Linux boards were inspired and designed due to the lot of e-mails and requests from customers of ours at the beginning on 2012 when Raspberry Pi had problems to arrange their production. We were asked again and again please do small low cost Linux computer, although at that moment we were just Linux users but never dealt with Kernel compilations, Device drivers build etc. this is what triggered us to go in this direction.

So if there was no Raspberry Pi there would not be OLinuXino as well, I admit it 🙂

Despite all problems Raspberry Pi had with the manufacturing start-up they now have sorted out their production problems and schematic mistakes, so the latest model-B works fine according to what we hear. I asked today friend of mine to borrow me one Pi to experiment with and this on the picture above is what we made.

We all know that Raspberry Pi $35 price is hard to beat, but looking at the additional accesoaries and boards which are sold for Raspberry Pi I can’t say the same for them.

To use Raspberry Pi to interface real world you need additional hardware and the prices of this after sale accessories are quite high, probably to adjust the not-so profitable Raspberry Pi sale price?

For instance the Gertboard which contain few ICs and components + blank board which harly cost more than $10 for the Raspberry Pi volumes is offered for $46!

The new PiFace board with two relays and 4 buttons announced price is $36.

What we did today is small Raspberry Pi GPIO to Breadboard adapter with UEXT on it.

We called it RPI-UEXT and will have these in stock in 2 weeks, what you can do with this breadboard adapter? Well this is basically same T-shape board as our AVR-T32U4 Arduino like breadboard board: https://www.olimex.com/Products/Duino/AVR/AVR-T32U4/

You can see it how it plugs to normal Breadboard here:

Image

The T-shapped boards was first invented by Ken Segler and we used for DuinoMite-TBA.

Every breadboard have two power supply busses on the top and bottom and there we run +5V/GND on top and +3.3V/GND on bottom. With the T-shapped board you make power supply available for breadboarding not only the GPIOs.
