Measuring approximately 20 x 17.5 mm, they have the ability to run well-known and popular microcontrollers such as the ESP32, RA4M1, nRF52840 y SAMD21, among others, which gives them incredible flexibility depending on the type of application required.
The different models in this family are designed to cover a wide variety of needs and range from boards that support connectivity Bluetooth 5.0 to those with Wi-Fi capability, or even models designed specifically for low-power machine learning.
Seeed Studio XIAO Family Models
Currently, the XIAO family has a total of ten different models, and although they all share many features, each of them has specific characteristics that make them unique. Below, we explore each model in detail:
- XIAO SAMD21: This was the first microcontroller in the XIAO family. It equips a ATSAMD21 de Microchip, offering a total of 11 pins, which can be used as digital inputs and outputs, ADC, PWM, DAC, I2C, SPI y UARTThis versatility makes it an excellent choice for small-scale projects or as an entry point for those new to development with XIAO boards.
- XIAO NRF52840: This model stands out for being the first in the family with wireless capabilities, integrating connectivity Bluetooth 5.0. Thanks to its processor ARM Cortex M4 and 2MB flash memory, it is ideal for projects that require low latency in data transmission. In addition, its wide variety of interfaces such as NFC and PWM make it even more attractive for portable and IoT projects.
- XIAO nRF52840 Sense: This is an advanced version of the nRF52840 model, with integrated sensors, which opens the door to projects related to the collection of environmental or motion data without the need to add additional hardware. This board is highly recommended for projects where multiple sensors are needed in a small space.
- XIAO RP2040: Based on the popular chip RP2040 Raspberry Pi, this microcontroller offers an excellent price-to-performance ratio. With its dual-core 133 MHz design combined with up to 16 MB of memory, it is perfect for more demanding projects that require greater processing and storage capacity.
- XIAO ESP32C3: This board includes the popular module ESP32 that many IoT developers already know and use. It supports Wi-Fi and Bluetooth, making it possible to use it in applications that require constant wireless connectivity. Its low power consumption makes it an interesting option for projects where battery life is a priority.
- XIAO ESP32S3: This model is an optimized version of the ESP32C3, with a better level of graphic processing and capabilities to develop projects. TinyML. It also includes connectivity Wi-Fi y Bluetooth, providing dual wireless connectivity.
- XIAO ESP32S3 Sense: One of the main features of this model is its set of additional sensors, just like the XIAO Sense. Recommended for projects that need advanced sensing capabilities and wireless connectivity in a compact package.
- XIAO ESP32 C6: This microcontroller is presented as an economical alternative within the range with WiFi connectivity, but with some limitations in terms of processing compared to the ESP32 S3.
Programming tools available
The interesting thing about family Seeed Studio XIAO is that they support a wide variety of development environments and programming languages, allowing both amateurs and professionals to easily integrate these boards into their projects.
Among the most commonly used languages ​​for programming models are:
- Arduino: A classic in microcontroller programming. All XIAO boards are compatible with this programming environment.
- MicroPython: For those who prefer a lighter, simpler approach, MicroPython runs seamlessly on these boards, allowing for faster programming without the need for heavy libraries.
- CircuitPython: This variant of Python is specifically designed for microcontrollers, and allows for very intuitive, yet powerful, development.
Compact size but big performance
As the name suggests, microcontrollers XIAO are incredibly small, with dimensions of only 20 x 17.5 mm. This is one of its main advantages over other platforms, as they allow their use in small spaces. In addition, thanks to their efficient design, the energy consumption of these boards is minimal, making them ideal for projects powered by long-lasting batteries.
Another notable detail is that most of the plates include ports in their design. USB Type-C, which makes it easy to program and connect to different devices. This is a feature that is appreciated by both novice and advanced developers.
In addition to their size and low power consumption, XIAO boards also include programmable LEDs that make it easy to identify states and allow the developer to create visual interactions without the need for additional resources.
It is important to mention that, although they are very compact plates, the The interfaces they offer are quite complete. Almost all models have pins that can be used for PWM, ADC, I2C, SPI and UART. This opens up a whole range of possibilities for connecting and controlling sensors, motors, displays and much more.
Which one to choose for each project?
The wide range of the XIAO family can be overwhelming if you are not sure which model to choose. In general, each of the microcontrollers is designed for a specific type of project. For example:
- If you need a simple microcontroller, but with good performance, the XIAO SAMD21 It is an excellent choice for starter projects.
- For wireless projects, the XIAO NRF52840 o XIAO ESP32C3 offer Bluetooth and Wi-Fi capabilities.
- If machine learning is your thing, XIAO ESP32S3 Or the version Sense They are the most recommended.
