Kit includes Relay Buddy tester, 5 new relay adapters and blow mold case.
Relay Buddy is a quick go/no go tester for the most common automotive relays.
With the included adapters, Relay Buddy now tests 5 different relay types and also tests shielded relays.
Relay Buddy will fail the relay and light the red LED if any of the test cycle proves unsuccessful during the test session.
Settable to 4 and 5-pin relay and uses vehicle's 12 volts battery for power.

8 kinds of rated voltages are adjustable, can apply to voltages in all regions of the world.
The working status of the relay is indicated by the LED indicator.
Ultra-small size and it is easy to install..
It is applied to mobile device connection control, causing accidents in equipment protection against reverse operation, normal/emergency power switch, preventing phase failure of power load..

Turn on and off lamps, fans, solenoids, and other small appliances(up to 250VAC or DC power) using any Feather board.
Compared to Adafruit's smaller Relay FeatherWings, this can handle a beefy 1200 Watts.
Works with all/any of our Feather boards, just wire up the relay control pin to whatever GPIO you like.
Connect a FeatherWing on top of your Feather board with Feather Stacking Headers or Feather Female Headers.
