  1. This bread board has two independent power supply design, one side of the switch is responsible for controlling the voltage, the voltage on both sides of independent design. Meanwhile groove design to maximize your bread board space savings. Learn More
  2. The Color sensor module based on TCS3200, which is a programmable color light-to-frequency converter, it could filter RGB data from source light and convert it to a square wave(50% duty cycle) with frequency directly proportional to light intensity (irradiance). The full-scale output frequency can be scaled by one of three preset values via two control input pins(SO, S1 Selectable Options 2%, 20%, 100% frequency),and pin S2, S3 to control the filter of RGB. Digital inputs and digital output allow interface to a microcontroller or other logic circuitry directly. Output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line. At last, user can calculate the color of the light by RGB values.

  3. 4 Frequency GPRS/GSM Module-EFCom Pro is an ultra compact and reliable wireless module. It is a breakout board and minimum system of SIM900 Quad-band GSM/GPRS module. It can communicate with controllers via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands). This module support software power on and reset. 
    EFCom Pro is base on SIM900 4 Frequency GPRS module

    The GPRS is configured and controlled via its UART using simple AT commands. Just connect on the Arduino/AVR/ARM/FPGA/CPLD board, you could easily use AT command to control it. EFCom Por can be connected to PC via FT233RL, recommend our FT232 Bee adapter

  8. Special Price $0.99

    Regular Price: $4.98

    This product is a carrier board or breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; we therefore recommend careful reading of the A4988 datasheet (380k pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil. It's equivalent to A4983-board but offers overcurrent protection. If the boards get too hot, they will interrupt the current until it cools a bit. If the current is too high for the heat sinking, the motors will pulse as the current is interrupted and restored.

  9. HB100 Miniature Microwave Motion Sensor is a X-Band Bi-Static Doppler transceiver module. Its built-in Dielectric Resonator Oscillator (DRO) and a pair of Microstrip patch antenna array, make it ideal for OEM usage in motion detection equipment. This module is ideally suitable for false alarms reduction in intruder detectors when work together with Passive Infrared (PIR) sensor. It can also be used for auto-door opening and vehicle speed measurement. Learn More
  10. GP2Y0D810Z0F is distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector) , IRED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. The output voltage of this sensor stays high in case an object exists in the specified distance range. So this sensor can also be used as proximity sensor. Learn More
