This is our most popular XBee wireless module: the series 1 802.15.4 protocol 1mW with wire antenna. Its good for point-to-point, multipoint and convertible to a mesh network point. We suggest this module for those starting out as it is the easiest to get going: if there are two XBees in the same area they will automatically 'sync' and pass serial data back and forth without any additional work or configuration What we like about the...

Just about all electronics use TTL serial for debugging, bootloading, programming, serial output, etc. But it's rare for a computer to have a serial port anymore. This is a USB to TTL serial cable, with a FTDI FT232RL usb/serial chip embedded in the head. It has a 6-pin socket at the end with 5V power and ground, as well as RX, TX, RTS and CTS at 3V logic levels. These are perfect for use with a Boarduino, Meggy's, or other Arduino...

This adapter board is designed to make adding wireless point-to-point or mesh networking easy. I looked at all the XBee adapter boards available and decided to design something better: Onboard 3.3V regulator to cleanly power your XBee, up to 250mALevel shifting circuitry means that its trivial to connect it to 5V circuitry such as an Arduino without risk of damageTwo LEDs, one for activity (RSSI), the other for power (Associate)10-pin 2mm...

Tweet-a-Watt is a DIY wireless power monitoring system. The project uses an 'off the shelf' power monitor called the Kill-a-Watt and adds wireless reporting. Each plug transmits the power usage at that outlet to a central computer receiver. The receiver can then log, graph and report the data. This pack contains nearly everything* necessary to build a single outlet monitor and receiver. To monitor additional outlets, you will need an add-on...

This pack contains parts to make an additional outlet for your Tweet-a-Watt setup. Included is XBee Series 1 module XBee adapter kit Bag of parts including 10,000uF capacitor, 220uF capacitor, 2 1% 10K resistors, 2 1% 4.7K resistors, 5mm green LED, 6" rainbow ribbon cable, and 2 pieces of 1/8" and 1/16" heatshrink * Please note, a P3 Kill-a-Watt is NOT included! You will need to buy this separately at a local hardware store, or online. They run...
