A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and at the same time, act to lower voltage levels within circuits. In electronic circuits resistors are used to limit current flow, to adjust signal levels, bias active elements, terminate transmission lines among other uses.

This is an IC base for 28 Pin IC's. This is used as a place holder for the 28 pin IC chips and is used in order to allow safe removal and insertion of IC chips because IC chips may become damaged from heat due to soldering.This base is very useful for your circuit because if your IC burns out you can easily change the IC without the need of desoldering. 

Order Code : RDL/28PB/13/001/V1.0

This tag is designed based on PCB and PPS base material, it is with water-proof, high washing cycle ability, Super acidic,Super basie.

ORDER CODE: RDL699

The PCA9685 is an I2C-bus controlled 16-channel LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 24 Hz to 1526 Hz with a duty cycle that is adjustable from 0 % to 100 % to allow the LED to be set to a specific brightness value. All outputs are set to the same PWM frequency.

ORDER CODE: RDL630

The RN2483 is a fully-certified 433/868 MHz module based on wireless LoRa® technology.  The RN2483 utilizes a unique spread spectrum modulation within the Sub-GHz band to enable long range, low power, and high network capacity.  

ORDER CODE: RDL787
