PiggyBack Board for Raspberry PI

[rudiratlos]

Hello,

we have developed a new board for the RPI with the following features and functions (for more details pls. see the attachment or watch the video on youtube):

- Real Time Clock (RTC) with battery backup
- IR Receiver for remote control of XBMC, OpenElec, Rasbmc
- Wireless Chip for communication in the 433MHz, 470MHz, 868MHz or 915MHz band
(platform for homeautomation (e.g. KNX, EnOcean ...), reading smartmeters (wMBUS...)
- Solder pads for temperature, barometric sensor and humidity sensor
- Breadboard area to implement your own functionality extensions
- overall low profile of the physical configuration

1. Demo Setup:
The servo board is connected on the I2C Bus of the piggy back board. iPhone sends yaw pitch and roll angle data of the internal motion sensors over WLAN. The RPI receives the motion data over UDP protocol and controlls the movement of the servo according to the motion angles.

2. Demo Setup:
a second RPI has a IMU board connected, sends the motion data wireless in the 868MHz frequency band. The second RPI receives the data and controls the servos.

Very interesting. Any chance of a link to that datasheet? The forum software has reduced it's size down below the point of legibility. Also, when will it be available? And of course, the most important question; what will it cost?

Same question here: looks really interesting, but when is it available (as a kit or completed) and how much does it cost?

I think I found it here:
http://shop.basis.biz/shop/index.php?la ... rd&cat=c27& for 41,65 Euro excl. Shipping.

But that site only ships to Germany.
The description also does not make really clear whether the Real Time Clock, IR Receiver, Wireless communication in 433MHz etc. are included in the kit.

If they are, I would very much be interested in ordering one provided it could be shipped to the Netherlands (just next door to Germany).

Right click on the image and click view image, you should see your mouse cursor as a + if so click the image.

Hi,

just got a new case from oneninedesign. cost @ 6 EUR.
The Pi with my piggy-back board are fitting perfectly into it.

The antenna, seen on the pictures, is for 433Hz.
For 868Mhz it's just half of the length.

Sorry for the quality of the pictures, but the forum alows picture uploading with a max. of 64KB / picture.

I have to say the 2nd video has got me thinking, one question, what software are you using to send the UDP multicast data, is it a commercial app or is the source code available for download? I'm a professional Objective-C programmer but never dabbled with UDP so this is an interesting project.

I fancy creating a fair ground grabber machine, three motors and a number of sensors.

Hello!
I'm looking for any troops of RFM22 libraries for Raspberry PI.
Of course if this kind of software doesn't exists I'll try to write something, but maybe someone could help me in finding an existing solution for this chip (write less - do more )

Hi,
Software Library can be found here: http://www.open.com.au/mikem/arduino/RF22/
Code has to be adjusted for the RPI-Interrupt- and Shutdown-Pin (see INT_RFM22 and RFM22_SD).

[infrat]

That's it! Thank's.

Nice work, but a power-circuit would make it perfect. A button that can power-on and power-down the Pi and the possibility for the LIRC circuit to do that too. I had started to design my own version using a PIC, but didn't find the time to finish it. Rough sketch is here.
Also you might like this.

Hello,

a NEW piggy back board revision is available now!

pls. see here: http://shop.basis.biz/shop/Raspberry-PI ... ack-board/

The new pcb revision 2 offers much more functionality than the old pcb.

- 1Wire bus has a level shifter to 5Volt signal level and an ESD protection diode. Now you can connect 1Wire sensors with a cable length of ~ 270meter
- IR Transmitter and Receiver devices are on the board, which are fully supported by LIRC
- Serial Port connector (compatible to groove extension boards. e.g. LCD, GPS ...)
- I2C Port connector (compatible to groove extension boards. e.g. Servo motor drivers, IMU ...)
- SPI Bus Port (a CAN board can be connected here)
- Real Time Clock (RTC) with Battery- or SuperCapacitor Backup
- Totally reworked bread board section
- very detailed kit assembly and software setup guide (more than 20 pages).
You can download it from here:

Hi infrat/rudiratios,
Need some help. Were you able to successfully use the RF22 library for the Pi with Si4432? I did not understand the statement :

Code has to be adjusted for the RPI-Interrupt- and Shutdown-Pin (see INT_RFM22 and RFM22_SD).

Could you explain how this needs to be done.

The RF22 library by mikem is primarily for Arduino as I understand. Can we make it work on Pi?

Thanks,
Hussain.

I want to connect a transceiver to raspberry pi
How to connect and configure 433Mhz transceiver with raspberry pi?
