These 10 segment bar graph LEDs have many uses. With a compact footprint, simple hookup, they are easy for prototyping or finished products. Essentially, they are 10 individual red LEDs housed together, each with an individual anode and...

These 10 segment bar graph LEDs have many uses. With a compact footprint, simple hookup, they are easy for prototyping or finished products. Essentially, they are 10 individual yellow LEDs housed together, each with an individual anode...

This is a 40-pin socket with 2mm pitch that mates with the popular XBee radio from Digi. Use this small part to avoid having to solder your precious radio to a PCB.

This is a 40-pin header with 2mm pitch that mates with our XBee socket . It can be used for making 'dummy XBees' or anything else you want!

Ideal for low power (nanoWatt) and connectivity applications that benefit from the availability of three serial ports: FS-USB (12 Mbit/s), I²C™ and SPI™ (up to 10Mbit/s) and an asynchronous (LIN capable) serial port (EUSART). Large...

Do you need a lot of space? But you need it in the size of your pinky nail? microSD (uSD) is here to save the day. TransFlash has now completed standards certification and is now known as microSD. Compatible with the SPI interface found...

Do you need a lot of space? EEPROMs not quite enough? How's 1GB sound? This is a socket used to interface to SD (Secure Data Disk) and MMC (Multi Media Card). We used it to test out our 'PIC to FAT16 on SD' routines. The SD/MMC cards use...

This is a small device called a reed switch . When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the...

DPDT Push-On/Push-Off Switch. Works great as general control switch.

The ATtiny84 is another of Atmel's little tiny 8-Bit Processors. 8K of program space, 12 I/O lines, and 8-channel 10 bit ADC. It will run up to 20MHz with an external crystal and can be programmed in circuit.

The MM74HC574 high speed octal D-type flip-flops utilize advanced silicon-gate P-well CMOS technology. They possess the high noise immunity and low power consumption of standard CMOS integrated circuits, as well as the ability to drive...

The ATmega8U2 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega8U2 achieves throughputs approaching 1 MIPS per MHz allowing the...
