Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name "XIAO" here represents its half feature "Tiny", and the other half will be "Puissant".

Compared to the regular XIAO BLE nRF52840 , this module adds two new sensors, an IMU and a Microphone.

Features

  • Versatile Microcontroller: Incorporate the Nordic nRF52840 chip with FPU, operating up to 64 MHz, mounted multiple development ports, supported by Arduino / CircuitPython
  • Wireless Capabilities: Implement Bluetooth 5.0, BLE functions with onboard antenna, also provide NFC connectivity
  • Elaborate Power Design: Provide ultra-low power consumption as 5 μA in deep sleep mode while supporting lithium battery charge management
  • Thumb-sized Design: 21 x 17.5mm, Seeed Studio XIAO series classic form-factor, suitable for wearable devices
  • Perfect for Production: Breadboard-friendly & SMD design, no components on the back

Seeed Studio XIAO nRF52840 Sense has an ultra-low power consumption of only 5 μA in the deep sleep mode, the embedded BQ25101 chip supports battery charge management which prolongs its use time. Moreover, Seeed Studio XIAO nRF52840 Sense supports the USB Type-C interface which can supply power and download code. It also has rich On-chip Memory of 1 MB flash and 256 kB RAM, and an Onboard Memory of 2 MB QSPI flash. There are 11 digital i/o that can be used as PWM pins and 6 analog i/o that can be used as ADC pins. It supports UART, IIC, and SPI all three common serial ports. 1 Reset button, 1 3-in-one LED, 1 Charge LED, and 1 Bluetooth antenna are on board, allowing developers to debug their code very easily.

As the advanced yet smaller version of the Seeed Studio XIAO nRF52840 , it carries two extra onboard sensors. One of them is a digital microphone created through Pulse Density Modulation(PDM) module on the nRF52840 chip. It can receive audio data in real-time which allows it can be used for audio recognition. The board can receive audio data through the MSM261D3526H1CPM microphone. The other one is 6-axis Inertial Measurement Unit(IMU) which can be applied in TinyML projects like gesture recognition.

The powerful performance makes it perfect for machine learning applications, and the tiny size allows it to be used in wearable devices and Internet of Things projects, not just for prototypes but the mass production. Furthermore, Seeed Studio XIAO nRF52840 is friendly to the communities for its strong software compatibilities, which supports Arduino, Micropython, and CircuitPython. Except for the software, flexible I/O allows it to speak to almost any external device.

Specification

To better support IoT and TinyML AI projects, there is an advanced version "Seeed Studio XIAO nRF52840 Sense" that carries an extra 6-axis IMU and a PDM microphone.

Well made, minor issue was quickly resolved
Size: Large, Color: Dinos Bruto (Purple)
I purchased the Dino Bruto Dog toy for my labradoodle who is quite fond of squeaky, squawky stuffed toys and oddly enough has shown a preference for purple. I opened the package with my hound standing by waiting for his gift. I detached the tags and attempted to squeak the toy. It seemed difficult to squeak or honk. I tossed the purple Dino Bruto to my dog who excitedly chomped to squeak. The toy squawked a couple times and then just quit. My poor hound was staring up at me with that "what's up with this" look on his face. I tracked down the website for the GoDog toys, not going through the Amazon return process. I called the good people at GoDog and stated simply that my dog's favorite part of the toy failed quite quickly and I was wondering about guarantees. I was told to go to the website and file a replacement request. The replacement request required that I include a photo which I did as directed. I received an reply email within a couple hours which stated that a new toy would be sent out shortly. I am happy to report that we received a replacement toy, not the purple Dino, but a colorful wood duck. The squawker device works well and is still performing like new more than a month later. It appears that the squeaker is not those little plastic squeakers but the bigger heavy plastic bag, bladder, with what I visualize as a duck call sort of sound device. I am guessing because I haven't seen the inside of the GoDog toys. I have seen the guts of other stuffed toys which use this type of noise device. While our dog seems to enjoy the sound of the plastic bag, bladder set-up squawkers, they seem to fail quickly and I tend to avoid them because of this. The toys using this type of squawker that I have seen, use what looks like a cheap lightweight plastic bag which is not securely attached to the "voice box". Since the GoDog replacement toy is holding up so well, I am guessing GoDog uses a heavier grade plastic bladder coupled with reinforced construction. The purple Dino Bruto toy still looks new even after multiple times of our hound grabbing the purple toy, shaking it at us with his invite to give chase or play keep away. Since the squawker failed so quickly with the new toy, I figure it was just a defective item which does not reflect the general quality of toys from GoDog. One evening our neighbor was visiting while his pitbull was playing in our yard with our dog. Our patio door was open so our dog ran into the house and grabbed his purple Dino Bruto toy. He is a bit of a show-off with new toys. Our dog then went racing back into the yard, shaking his GoDog toy at the pitbull. A quick game of tug-of-war ensued. Since this is a new toy, our neighbor leaped into the game and took the toy away from the dogs. In that short time of tugging between the dogs, the toy held together and did not even pull apart at any of the seams. There were no puncture marks either. This is a game our dog has initiated before with the neighbor pitbull. Normally, the stuffed toys are ripped apart almost immediately. I was surprised and impressed with the quality of the sewing which appears to employ some sort of reinforced construction or heavier material. I plan to make more purchases from GoDog toys. The toys are a little more expensive than some stuffed dogs toys but they hold up so well I figure they are worth a few more dollars. They are great toys that hold up well and the company provides quick responses to inquiries. I consider this a winning combination.

Good quality

we’ve had many godog toys over the years and although my dog eventually rips through them I do find that they last longer than other cheap toys. Overall very well made!

Cute and fairly long lasting
Size: Large, Color: Dinos Frills (Red)
Lasted from Nov 13th, 2024-August 20th, 2025 lol very impressive. She played with it nearly daily and loved the big squeak. The squeak box was just ripped out so she probably won’t play with it anymore. Happy to order another!

He was OBSESSED!!!
Size: Large, Color: Dinos Frills (Gray), Size: Large, Color: Dinos Frills (Gray)
Our year and a half old lab was excited the moment he saw it come out of the box ! He had many toys that he tore into shreds within a day so this was his first “heavy toy “ that wasn’t easy to tear . I think he loves the design and feel of it , as he carried this thing EVERYWHERE and even to bed . Him and his sister share toys but this was his , he claimed it lol Now if it wasn’t for us telling him to stop trying to kill the Dino he could have easily tore into this thing within a couple of days . However since he started chewing gently he became obsessed with the squeaker , and used that as an alarm that he was up every morning in bed 😂 The quality of the product is actually pretty good but it’s not bullet proof, and our smart dog was able to sneakily tear a whole in the nose and some how pull out the stuffing . All in all I would definitely buy another toy from this company because they are made with quality for dogs , and lasted about three weeks longer than his average toys ! It was his favorite toy 💕

Not indestructible
Size: Large, Color: Dinos Frills (Gray)
When I googled “indestructible stuffy dog toys” this popped up. My 9 month old pup loves stuffies but destroys them quickly and eats stuffing if not caught quickly. Well, this indestructible toy is cute but my dog had it torn apart in under 4 minutes so…🤷🏻‍♀️
