Due to strong demand, the JeeLink 868 MHz is temporarily out of stock. Shipments should resume Monday, 4th August.
The JeeLink is a fully assembled and ready-to-use USB-type “stick” which plugs directly into a PC, Mac or USB hub. It contains Atmel’s ATmega328p AVR microprocessor and HopeRF’s RFM12B wireless radio module. The processor chip is pre-flashed with the OptiBoot loader (compatible with the Arduino Uno) and the RF12demo sketch. See the JeeNode description for more details.
Unlike JeeNodes, JeeLinks do not have any external ports to connect plugs or other components. The JeeLink comes in a clear plastic case and is intended as a wireless interface between other JeeNodes and an attached PC or Mac (via USB).
The JeeLink v3 also has 16 Mbit of flash memory, which can be used to collect data. An on-board accurate 10 ppm crystal helps keep track of time, even when the attached computer is sleeping.
The on-board wireless radio module is the same as on JeeNodes. The standard JeeLink 868 comes with the RFM12B ISM-band 868 MHz radio module (as used across Europe). *Chose this variant* unless you have a special compatibility requirement with equipment that uses a different ISM band.
For the 868 MHz ISM band, chose the JeeLink 868 option.
For the 433 MHz ISM band, chose the JeeLink 433 option.
For your own choice of radio module, chose the JeeLink NoRF option.
For the 915 MHz ISM band, refer to the Modern Device shop (US$ prices).
