Description

2-CH Triac Dimmer HAT for Raspberry Pi, Integrated MCU, UART / I2CThis is a Bidirectional SCR Isolated HAT, Dual Channels Triac Output Control, ideal for lighting and industrial motor automation projects. This includes smart lighting, controlling motors for things such as ventilation, pump control, valve control, heating and air conditioning systems etc.. Basically anything that runs on mains A C power, either through a switch or variable voltage current control. This device has some advantages over a traditional

This is a Bidirectional SCR Isolated HAT, Dual Channels Triac Output Control, ideal for lighting and industrial motor automation projects. This includes smart lighting, controlling motors for things such as ventilation, pump control, valve control, heating and air conditioning systems etc.. Basically anything that runs on mains A/C power, either through a switch or variable voltage/current control.

This device has some advantages over a traditional relay since is offers higher efficiency, no mechanical wear, along with quicker response and adjustable outputs.

Key Features

  • STM32F0 MCU controller, requires minimal Raspberry Pi resource, UART / I2C communication
  • RC snubber circuit, protect the triac from power fluctuation
  • Up to 4400W output power, under ideal heat dissipation condition
  • Optocoupler isolation, preventing interference from the high voltage circuit
  • Indicator for easy checking the status of triac
  • Reserved UART and I2C interface, for working with other host control boards
  • Data rate: up to 921.6kbps for UART，up to 1024kbps for I2C
  • Comes with development resources and manual (examples in C and Python)

When connecting this to your Raspberry Pi, or Jetson Nano development board (this board uses the RPI standard 40pin GPIO header), you can easily interface high voltage devices such as hosehold lighting, or industrial pumps/motors to your automation project.

STM32F0 MCU Onboard

Integrates STM32F030 MCU, Supports Directly Command Control, Easy For Developping Quicker Response, Requires Minimal Resource From The Raspberry Pi

High Data Rate, Always One Step Ahead

Up To 921.6kbps For UART，Up To 1024kbps For I2C

Powerful Output Power

Up To 4400W Output Power, Under actively cooled environments (extra fan required to ensure proper heat dissipation)

Optocoupler Isolation Safety First!

Optoisolated Solution, Preventing Interference From The High Voltage Circuit

Warning: Please never touch the high voltage circuit on this board, and always make sure you install with sufficient insulation and isolation to avoid any contact with the board while it is under power.

Great buy
Color: White, Size: Queen (Pack of 2)
I was very skeptical about buying pillows online. I am pleasantly thrilled with these pillows. They are great quality. They maintain their shape by simply shaking occasionally if needed. The fabric is really soft to the touch. They don't go flat after a few uses. I've had them for almost 6 months. I waited to review to make sure they didn't disappoint.

LOVE THEM!!! SAVED MY NECK!!!
Color: White, Size: Queen (Pack of 2)
Hallelujah!!! After spending so much money on pillows that didn't work for my aching neck and shoulders, I finally found pillows that works for me and I am SOOOOOO excited. I had my 1st night of comfortable sleeping after years of restless, painful nights. These pillows are the BOMB! I kid you not. I have spent hundreds of dollars on pillow to no avail. I mean, the expensive hotel pillows that were suppose to make you feel as if you're sleeping on clouds made my neck stiff and painful. Let's not talk about that "infamous pillow: advertised on the infomercial that was suppose to be the #1 pillow to fight against neck and back pain. Shhhh, we won't say the name but uh....TRASH. Ok, I'm back. Lost it there for a moment thinking of all the money I wasted on all those pillows that claimed to be "THE PILLOW." LOL..what a joke. So, anyway back to what I was saying about this pillow beauty. The very 1st night I slept on it, I'll admit I was skeptical when I laid down. Scared I was going to wake up with a sore neck and headache to go along with it. I tore the package open, let the pillow inflate, fluffed them with my hands and allowed them to sit for a few hours. I didn't wait the allotted time suggested because I was too anxious to try them and it was almost my bed time. So, excitedly I jumped in bed, laid my head down on the pillow and immediately thought, "oh no, these are too soft. This will not work." I just knew I would wake up to a sore neck. Cautiously, I laid down and waited to drift off, dreading waking up the next morning with a stiffer. (LOL) To my surprise I actually slept all night too. I usually would wake up like a thousand times fighting with repositioning the pillow to find my comfort zone. WOW, not that night. I slept like a baby and wait for it.....I woke up the next morning with NO PAIN! Hallelujah! I couldn't believe it. I was literally pain free in my neck and did not have a headache from the strain on my neck, shoulders and back. Man, is this really happening, I asked myself. This just can't be real. Wake, wake girl. You are dreaming. But nope. I was fully awake and with a pain free neck and shoulders. I jumped up and started getting ready for my day. I finally found the pillow that I wish I had found years ago. Could have saved so much $ from going down the drain. I am SO thankful to all the reviews that I read that shared their positive experience and encouraged me to purchase for myself. I am SOOOO GLAD I took a chance and brought these little beauties. They saved my neck and my sanity. Thank you EIUE Hotel Collection for inventing the pillow that is reasonably priced and that does the job it's intended to do. Allow people to have a good nights rest WITHOUT neck, shoulder and back pain. Your Rock! This is a real review and I am a real person.

Flat

They are long pillows but definitely flat, I tried and tried to fluff them up and they are about like the $3 Walmart pillows. I will be returning these

Holy Wow!
Color: White, Size: Queen (Pack of 2)
These pillows are so fluffy and material is really soft. They came vacuumed packed. I thought well this will be a return for sure. Followed the directions and placed them in my dryer for 15 minutes. Could not believe how big and fluffy they were. My company always ask for the link and I have ordered them for family members and for myself 4 times. Mine I’ve had over a year and have kept their shape and fluffiness. If you like a fluffy pillow…this is the one. They are the best!!!

Comfortable and good quality
Color: White, Size: Queen (Pack of 2)
So comfortable! We stayed at an Airbnb that used these pillows and went home and ordered some! These are similar to another more expensive pillow I’ve used but way better price. The filling feels nice and they don’t go flat or get lumpy so far.
