The M24SR-DISCO-PREM is a Demonstration Kit to evaluate the features and capabilities of the M24SR series and is based on the M24SR64 device. The M24SR64 device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a 64 Kbits EEPROM memory. It can be operated from an I²C interface or by a 13.56MHz RFID reader or an NFC phone. The I²C interface uses a two-wire serial interface, consisting of a bidirectional data line and a clock line. It behaves as a slave with respect to the I²C protocol. The RF protocol is compatible with ISO/IEC 14443 Type A and NFC Forum Type 4 Tag. The board is powered through the USB bus. It also includes a microcontroller STM32F103 to drive the EEPROM via I²C and the LCD screen via SPI bus.
- 31 x 30mm 13.56MHz double layer inductive antenna etched on PCB (ANT14)
- STM32F103RGT6 64LQFP 32-bit microcontroller with 1MB flash memory
- USB micro-B connector for board powering
- JTAG connector for microcontroller firmware upgrade and debug

Love this toothbrush!
I absolutely love the Bamboo Soft Bristle Toothbrush—5 stars all the way!
Pros:
The soft bristles are gentle on my gums but still do a great job of cleaning my teeth. I’ve noticed my mouth feels super fresh after each use.
The bamboo handle is lightweight and comfortable to hold, and I love that it’s eco-friendly. It’s a great way to reduce plastic waste!
It’s durable—so far, the bristles haven’t frayed, even after several weeks of use.
Cons:
The bamboo handle can feel slightly rough when it gets wet, but it’s not a big deal.
It might take a little getting used to if you’ve only used plastic toothbrushes before.
Overall, this toothbrush is a great sustainable option without sacrificing performance. I’m definitely sticking with it and recommending it to everyone!

Could use some adjustments
Brush has a large head, prefer it smaller with contour to get in between teeth. States that it's soft, but softer would work better. Overall, it does not seem to clean well on curved tooth surface. Brush itself appears to be of good quality if its in fact real bamboo and plant based bristles (not plastic).

Brushing your teeth now good for the environment as well as your health!
These are sturdy toothbrushes, light weight, and easy to use. I especially like the idea that I'm not contributing more plastic to the environment using regular toothbrushes.

Great value, good suds, good quality, good for the environment
Color: 5 Pack
Goodness I love these.
I moved within the last several months, and my new town and state is not as on top of recycling as my old state was. This isnt a super huge problem, but it meant I had to start finding ways to reduce my refuse. Less bottles.
So naturally I switched to bar soap. I also knew I wanted to stop using those plastic net poofs. I didnt have easy access to a washer, and I hate laundry anyway.. so washcloths arent a huge part of my life.
What was a girl to do?
Buy these.
Thats what everyone should do.
They hang nice. My soap dries. It exfoliates amazingly without being too rough. I tried another brand before this and it was *blows raspberry* 💩. Fell apart super easy, didnt suds up well.. just no.
But this one I love. The soap I bought fit just fine, but took up the whole net. I didnt like that. It didnt dry as well or suds up at all. So I started cutting my soap in half and now it works GREAT.
Warning - its not good on your private bits. Itll scratch you the heck up. You shouldnt be using anything on your private bits other than soap and your hand anyway. I also recommend harder bars of soap. Super soft super lotion infused bars dont seem to hold up as well.
If youre trying to reduce your plastic waste and like feeling amazingly exfoliated, this is for you.

This handy little tool holds my soap and exfoliates my skin gently.
Color: 5 Pack
I bought this as a bag for my new shampoo bar so it'll last longer. This bag generates a nice lather, hangs off my shower caddy, and allows the bar to dry between uses. Makes shampoo bars much more convenient. The texture of the pouch remains scratchy after 3 or 4 uses so far but it produces a good amount of lather in combination with my bar soap. Hoping it softens up with use. Very good for exfoliating! The bag does have a canvas scent to it, but once you add water and lather up the soap inside it disappears. I love this bag. We always have a bunch of soap pieces in a basket on our tub, and now we can use them till there’s nothing left! My husband's biggest complaint when convincing him to switch to bar soaps with me was that they are so slippery in the shower and difficult to use. This thing is the ANSWER! It's the perfect sudsy, exfoliating grip for bar soaps that is still eco friendly - plus, the string is great for hanging on the shower head after!
