Olimex Links and Prices
Links: Olimex have upgraded their web site and many of the old graphics and document links no longer work. If you are missing links, navigate to the same product on the Olimex site, which is in a similar directory structure as ours, and you will find the correct links. We did try to advise Olimex of the coming problem years ago, and the easy fix, but we weren't able to convince them. By giving link names to specific file names (including versions), the problem will continue.
Prices: This Dontronics supplied Olimex manufactured board, is the same price (or less) than the Olimex Retail price.
- DEVELOPMENT BOARD WITH ATMEGA32 AND 3 BAND GSM GPRS MODULE 850/900/1800MHZ
is excellent board for adding remote monitoring and control in remote places
by GSM cellular network. Do you want to switch on/off your local heating
in your mountain house? To monitor the temperature at up to 8 remote points
up to 30 meters away from the module? To listen what happens in your house
with silent call after you get message for alarm status? Then AVR-GSM is
the board for you! It contains ATmega32 microcontroller and 3-band GSM
GPRS module 900/1800/1900Mhz inside which covers most used GSM networks
around the world. The GSM antenna is build in the board so no need for
external expensive GSM antennas. AVR-GSM have two relays 240VAC/10A, two
optoisolated inputs which could be connected to alarm sensors or just buttons
for user actions (like call pre-loaded phone numbers), on-board temperature
sensor and connector for additional up to 8 addressable remote temperature
sensors at up to 30 meter distance from the module. Normal phone hook can
be connected to this board and to allow user to speak, listen, taking and
placing phone calls as normal stand alone cellular phone. AVR-GSM can be
connected to PC with the USB connector it have and it is recognized as
modem which could be used to add internet via GPRS to your computer (imagine
how useful is this for your mountain house if there is no internet but
only cellular network!).
