Features:
Tiny and breadboard/protoboard-friendly, leaving plenty of room for other connections
5V or 12V DPDT latching relay, with LEDs showing set and reset pulse.
Assembled versions are made and fully tested by a human - ships in anti-static bag.
Kits are great for a little soldering project or for educational purposes.
Kits arrive in an anti-static bag containing all electronic components, bare PCB, headers, and link to downloadable assembly guide online
Product Description:
This series of small breadboard-ready relay breakout boards was brought about while prototyping audio circuits. The relays with non-breadboard-friendly pitches that were being tested with became frustrating, so it was decided to fab some modular options that can be placed neatly on a breadboard or a more permanent protoboard.
This model uses a 5V or 12V DPDT dual-coil latching relay. Note that since this is a latching relay, it only needs a momentary pulse (>10ms) to activate either of the coils. The relay will then hold the position of whichever state it was set to last, even through a power-cycle. Not having to actively hold the state will save you power. Note, the LEDs will light up only during this momentary pulse.
Unlike the Transistor-controlled version (see other product variations), this model leaves it up to you to determine how you want to trigger the relay coils.

Relay Specs:
EC2-5TNU / EC2-12TNU Contact Ratings:
Maximum Switching Power 60 W, 125 VA
Maximum Switching Voltage 220 VDC, 250 VAC
Maximum Switching Current 2 A
Maximum Carrying Current 2 A
Dimensions:
36.25mm x 15.9mm (1.43in x .63in)
Header pins are standard 2.54mm (.100") pitch
NOTE: This PCB is built for a breadboard or low signal protoboard. A typical solderless breadboard's contacts are rated for 5V at 1A, or 15 Volts and 333mA. Just because the relay is rated for bigger stuff, doesn't mean you should run big stuff through your breadboard. Don't do it!
