JeeNode Development Platform

It is basically a nice compact layout for an Atmel Atmega 328 with a wireless module.  Fully compatible with the Arduino IDE.  The JeeNode is available in kit form, but also all schematics and CAD files are available to download. It looks like they are mainly using it for home monitoring and control.  So far we’ve seen them put a temp sensor, power metering, and IR LED modules on their flickr set.

  1. What about just using a Zigbit module? They’re basically ATMEGA chips with a built-in Zigbee radio + AMP. In the UK they cost about £25 from Farnell. Maybe this JeeNode is cheaper?

  2. A JeeNode (kit) costs €17.50, which is under £16– crazy cheap! ZigBee is fantastic, but too expensive for many microcontroller projects, thought the ZigBit module really brings down the price by integrating it with the controller. Wish I could find availability in the US though; min. quantity 122 at Mouser! Anyway the JeeNode comes preloaded with the Arduino bootloader, so… er [ducking].

    If you want IO, the ATMEGA644P is the way to go. Check out the Sanguino project. The ATMEGA644P gives you two serial lines, which means you can hook up any radio transceiver in addition to a GPS unit or other serial device without having to use SoftwareSerial. Win!

    Certainly fewer ports overall. However, if you look at the full documentation at it says that two of the 4 DIO pins allow PWM.

    If you want a small form factor on the arduino platform, but more pins, you could always pick up an Arduino Pro Mini (or a Sanguino as Simmers suggested) and a wireless module and make your own.

  5. @Cynyr (and everyone), of the 18 normally available Arduino pins, JeeNode only uses five for the RFM12B interface– D2 and D10-D13. Ports 1-4 each have 2 pins, plus they share D3 (also PWM), so that’s 9, plus two each via the I2C (A4, A5) and SPI (D8, D9) headers: 13 pins are available, plus TX and RX.

    Modern Devices also carries a JeeLink, essentially a stripped down Jeelink with USB and a large flash memory (for when the computer crashes). Modern Devices is having trouble delivering at the moment.

    The “IRQ” pin is PWM pin 3, the downside is its repeated on all 4 “ports”. I didnt look where the other 3 go, as I only needed 3 at that moment.

    I’m the one working with them, thats my picture up there. Jean Claude (the originator) has done much more, and I’m following in his footsteps.

  7. @Cynyr..

    Forgot to mention, those are just the pins conveniently broken out and put on receptacles. You can get at the others, they are brought to pads and you can also tack solder directly to the 328. Its essentially an Arduino, on a thin board with different terminations.
