JeeLink (v1)
The JeeLink is a small module in the shape of a USB stick, with an Atmel ATmega processor and a HopeRF wireless radio.
Differences with the JeeNode:
- the size of the JeeLink differs slightly from the JeeNode
- the FTDI connector is replaced by a USB plug and on-board FTDI chip
- the I2C / PWR and SPI / ISP headers are in a slightly different position
- two extra A6 and A7 analog lines are brought ought to additional pads
- there are two LEDs to signal RX and TX activity
- the JeeLink has a reset button right next to the USB plug
- the resonator has been replaced by a crystal for improved time accuracy
- all compontents are surface-mounted instead of through-hole
- apart from these differences, the JN3 Specs lists further details
