Description of 8 Channel Relay Module Board For Raspberry Pi 4B/3B+/3B/2B/A+/B+/Zero

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano. High quality relays, loads up to 5A 250V AC or 5A 30V DC. Photo coupling isolation, prevent interference from high voltage circuit. Standard rail mount bottom case. Onboard LEDs for indicating relays status. Relay control pin selection jumper, allows to control the relays by custom pins other than the default pins. Reserved control Interface, allows to work with controllers like PLC. Power supply voltage: 5V. Trigger signal: 3.3V/5V. Relay channels: 8-ch. Contact form: SPDT-NO,NC. Closed current: 6mA (per channel). Connector: screw terminal block. Dimension: 232 × 72 (mm). Mounting hole size: 3.0mm.

Good for environmental monitoring

Connected to my Raspberry Pi and the example code worked without any modifications. One day the developers gave me a written license for the code, modified it to monitor Nagios and it worked like clockwork.

Pros
  • Bottom housing for standard rail mounting. Built-in LEDs to indicate relay status. The relay control contact selection jumper allows the relay to be controlled with user-defined contacts other than the standard contacts. Reserved control interface, allows working with PLC controls.
Cons
  • Could have chosen a newer model

Excellent sensor, configured but missing documentation

I bought this for a university class. The best part is that no soldering is required, everything comes neatly and ready to be connected to your Arduino or your Raspberry Pi just like I did in the photo. The bad thing is that there is documentation or lack thereof. That's why I'm giving it 4 stars instead of 5. I was able to record instant data like temperature and humidity, but like printing, it wasn't all that easy. In general, if you only need it for those sensors (temperature and humidity)…

Pros
  • Standard Raspberry Pi 40PIN GPIO expansion connector, supports Raspberry Pi series cards, Jetson Nano. High-quality relay, loadable up to 5A 250V AC or 5A 30V DC. Photocommunication isolation, prevents interference from high voltage circuits.
Cons
  • Almost everything is there

Not working

I worked with it for three days - I tried everything I could think of. I've tried many other motor drivers with both Raspberry Pi and Arduino and never had so many headaches. The documentation is bad. After all, I've never managed to get a stepper motor to spin; he just twitched back and forth. [Using Raspberry Pi 4B]

Pros
  • Supply voltage: 5V. Trigger Signal: 3.3V/5V Relay Channels: 8ch Contact Form: SPDT-NO,NC.
Cons
  • There are doubts

Works well with Raspberry Pi

Works well with a Raspberry Pi with two 24V stepper motors Example code is available on the vendor's wiki page. These hats don't seem to stack.

Pros
  • Off-state current: 6mA (per channel). Connection: screw terminal block. Size: 232 × 72 (mm). Mounting Hole Size: 3.0mm
Cons
  • ---

Can't get started

I worked on it for three days and tried everything. I've tried many other motor drivers with both Raspberry Pi and Arduino and never had so many headaches. The documentation is bad. After all, I've never managed to get a stepper motor to spin; he just twitched back and forth. [Using Raspberry Pi 4B]

Pros
  • Computers and accessories
Cons
  • Lots of stuff

Great sensor set up but no documentation

I bought this for a university course, the best part is no soldering is required everything is neat and ready to hook up. to your Arduino or Raspberry Pi as I did in the photo. The bad thing is that there is documentation or lack thereof. That's why I'm giving it 4 stars instead of 5. I was able to record instant data like temperature and humidity, but like printing, it wasn't all that easy. In general, if you only need it for those sensors (temperature and humidity), go ahead. that will work…

Pros
  • Electronics
Cons
  • I don't remember but there was something
