JeeNode v2

1. • 6-pin FTDI-compatible serial I/O port, used for power, re-flashing, and communication
   • 3.3V power regulator which accepts 3.5 … 13V as external power source
   • 8-pin combined Power / Serial / I2C / Extended (PSIX) connector
   • ATmega328P microcontroller by Atmel, with 16 MHz ceramic resonator
   • 2x4-pin combined SPI / ISP connector, with 2 general-purpose I/O lines
   • RFM12B wireless RF module for the 433, 868, or 915 MHz ISM band, by Hope RF
   • short wire - acts as radio antenna (78, 82, 165 mm long, for 915, 868, 433 MHz, respectively)

Boarduino (http://www.adafruit.com/product/91)

• • Designed to plug into a breadboard for easy prototyping

1. • Petite size, only 2.75" x 0.8" (75mm x 20mm)
   • All 'standard' pins are brought out - Digital 0-13, Analog 0-5, ARef, 5V, 3V, Ground, and Reset
   • Chip comes pre-programmed with a "no-wait" Arduino bootloader (Read more here)
   • 4 LEDs! There's a green power-good LED, a red "pin 13" LED (just like the Arduino), and a pair of RX and TX indicator LEDs for debugging the serial connection
   • Nearly-all-surfacemount design. We left the chip as through-hole to make it easier to upgrade and repair. All surface mount parts are pre-assembled and tested.
   • Reset button
   • ATmega328P, running at 16.00 MHz, just like all Arduinos
   • 6-pin standard ICSP header
   • USB miniB jack
   • 500mA fuse protects your computer's USB port from overcurrent
   • Auto-reset capability
