Want to connect several Seeed Studio Grove modules to your Arduino board? The Arduino MKR CONNECTOR CARRIER is the perfect companion for Arduino MKR boards and a Grove ecosystem. Do you have severa...

Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor breakout board, starring the CAP1188. This chip can handle up to 8 individual ...

8-channel Bi-directional Logic Level Converter - TXB0108 Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers fi...

DESCRIPTION FRAM, or Ferroelectric Ram, is the coolest new data storage method that all the fashion magazines are talking about. Oh wait, no that's quilted handbags. But FRAM is pretty damn cool to...

The Arduino 4 Relays Shield allows your Arduino driving high power loads that cannot be controlled directly by Arduino's digital pins. The Shield features four relays, each relay with 2 pole change...

DESCRIPTION The biggest NeoPixel Ring yet! With four of these you can make a huge ring with 60 ultra bright smart LED NeoPixels are arranged in a circle with a 6.2" diameter. Each order comes with ...

Universal circuit board for 2-way to 4-way crossovers, with even thicker copper layer; impedance compensation and level reduction possible. Material: Epoxy glass

Crossover made of high-grade copper coils and low-loss audio frequency electrolytic capacitors, mounted on epoxy PC boards. Checked with regard to functioning, slope steepness and cross-over freque...

DESCRIPTION Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of...

DESCRIPTION This pressure sensor from Freescale is a great low-cost sensing solution for precision measurement of barometric pressure and altitude. The MPL3115A2 has a typical 1.5 Pascal resolution...
