The JeeNode USB is a JeeNode with an built-in USB interface. It has exactly the same size and connectors as the original JeeNode (except FTDI).

Differences with the original JeeNode:

• the FTDI connector is replaced by a USB plug and on-board FTDI chip
• there are two LEDs to signal RX and TX activity
• there is a blue "activity" LED, connected to PB1
• there is a small reset button between ports 3 and 4
• there is an on-board Lithium Polymer battery charger with orange "charge" LED
• the PWR pin operates at 4.2V when plugged into USB
• total current draw is limited to 280 mA (max LiPo charge current)
• all compontents are surface-mounted instead of through-hole
