The Whadda 8 CH Relay Module is an 8-channel relay board designed for electronics makers, hobbyists, and prototyping projects. It enables control of up to 8 separate circuits with a single control signal, making it a versatile building block for automation and DIY electronics.
8 independent relay channels allow simultaneous control of multiple circuits from one microcontroller or development board
Maximum switching voltage of 250 V provides compatibility with a wide range of household and industrial loads
Compact relay module format fits standard breadboards and prototyping setups without additional wiring adapters
24 months manufacturer warranty ensures long-term reliability for ongoing projects and experiments
What sets the Whadda 8 CH Relay Module apart
Unlike basic single-channel relay boards, this module integrates 8 optically isolated relay channels on a single compact board. The 250 V maximum switching rating means it can handle mains-voltage loads safely, while the standard relay module footprint keeps it compatible with Arduino, Raspberry Pi, and other common development platforms.
Ideal for...
Electronics students, makers, and hobbyists who need to switch multiple loads from a single microcontroller output. Also suited for light automation projects such as controlling lamps, small appliances, or sensors in a prototype environment where reliable galvanic isolation between control and load circuits is required.
Application of Whadda 8 CH Relay Module
Connect the module to a microcontroller or development board via the standard relay module interface pins
Wire each of the 8 relay channels to the load circuit, respecting the 250 V maximum switching voltage
Provide the appropriate control signal to activate or deactivate each channel independently
Use the optically isolated design to protect the control circuit from voltage spikes on the load side
Whadda is a brand focused on electronics components and development boards for makers and hobbyists. The product range covers relay modules, sensor boards, and prototyping accessories. Whadda products are distributed through Brack/Alltron and are commonly used in educational and DIY electronics projects.
It is used to control up to 8 independent circuits from a single microcontroller or development board output, enabling automation and switching of loads in prototyping projects.
Each relay channel supports a maximum switching voltage of 250 V, making the module suitable for a wide range of household and light industrial loads.
The module has 8 independent relay channels, each capable of switching a separate circuit with optical isolation from the control side.
The delivery includes one Whadda 8 CH Relay Module. Mounting hardware and connection cables are not included and must be sourced separately for prototyping use.
Yes, the product comes with a 24-month manufacturer warranty covering defects in materials and workmanship under normal use.
