The JeeLink is a small module in the shape of a USB stick, with an Atmel ATmega processor and a HopeRF wireless radio.

Note: the previous JeeLink version (JL1) has a different form factor and is now called a ?JU1.

Differences with the JeeNode USB:

• different form factor, enclosed in a plastic case
• no pins or port connectors to attach anything to
• includes 4 Mbit of flash memory, connected via SPI
• uses a 10 ppm crystal for improved time-keeping accuracy
• no reset button

How to Get It

Pre-assembled units and boards are available in the Shop.
Or create your own boards with these EAGLE files: jlpcb-030.pdf / jlpcb-030.sch / jlpcb-030.brd.

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).
