The JeeLink is a small module in the shape of a USB stick, with an Atmel ATmega processor and a Hope RFM12B wireless radio.
Note: the old JeeLink version JL1 had a different form factor, as predecessor of what is now the JeeNode USB.
Differences from the JeeNode USB:
- different form factor, enclosed in a plastic case
- no pins or port connectors to attach anything to
- includes 16 Mbit of flash memory (M25P16 8-SOIC), connected via SPI
- uses a 10 ppm crystal for improved time-keeping accuracy
- no reset button, no LiPo charger
How to Get It¶
Pre-assembled units and boards are available in the Shop.
Or create your own boards with these EAGLE files: see below.
Dimensions: 19 x 49 mm (board), 23 x 71 x 8.7 mm (enclosure)
Everything is provided as open source, both hardware and software.
How to Use It¶
With RF12demo loaded, you can turn on the blue LED with "1l" (1 + lowercase L).
A JeeLink is mostly the same as a JeeNode and JeeNode USB, so have a look at the JeeNode page.
Note: the JeeLink v3 uses the OptiBoot loader, i.e. it's compatible with an Arduino Uno.
