Arduino MKR WiFi 1010 32-bit WiFi & Bluetooth Dev Board

The Arduino MKR WiFi 1010 is a compact, secure development board combining a 32-bit ARM Cortex-M0+ microcontroller with built-in WiFi and Bluetooth for fast prototyping of connected projects.

Designed to bridge the gap between simple microcontroller boards and more complex IoT platforms, the MKR WiFi 1010 packs wireless connectivity, plenty of memory, and versatile I/O into a small, hobbyist-friendly form factor. It’s compatible with the Arduino IDE and supports common serial and bus protocols, making it suitable for cloud-connected sensors, wearables, robotics controllers, and rapid prototyping.

How powerful is the processor and memory for IoT projects?

The board runs a 48 MHz SAMD21 ARM Cortex-M0+ core that handles typical embedded and wireless tasks efficiently. With 250 KB of flash and 32 KB of SRAM, it can store larger sketches, manage network stacks, and buffer sensor data without frequent memory limits.

• 32-bit ARM Cortex-M0+ processor at 48 MHz for responsive control loops
• 250 KB flash for bigger firmware and libraries
• 32 KB SRAM to support runtime buffers and network operations

What wireless features does the MKR WiFi 1010 provide?

Connectivity comes from the integrated NINA-W102 radio module, offering both WiFi (802.11 b/g/n) and Bluetooth Low Energy. This dual-radio setup lets you connect to the internet and nearby BLE devices simultaneously for versatile IoT topologies.

• WiFi 802.11 b/g/n for cloud services and web APIs
• Bluetooth Low Energy for mobile pairing and sensor links
• NINA-W102 module simplifies integration and driver support

Which input/output and expansion options are available?

The MKR WiFi 1010 exposes 14 digital I/O pins—six of which support PWM—and six analog inputs with 12-bit resolution. Standard serial interfaces like I2C, SPI, and UART are available for connecting sensors, displays, and other peripherals, and the board follows the MKR pin layout for shields and accessories.

• 14 digital pins (6 PWM-capable) for motors, LEDs, and switches
• 6 analog inputs with 12-bit ADC precision for sensor readings
• I2C, SPI, UART support for displays, sensors, and external modules

Is the MKR WiFi 1010 easy to program and secure for networked use?

Yes — it's fully supported in the Arduino IDE, with libraries for WiFi, BLE, and popular cloud services that speed development. The board also includes a secure element for credential storage, improving protection of keys and certificates when connecting to networks and services.

• Full Arduino IDE support and extensive community examples
• Prebuilt libraries for WiFi, BLE, and common IoT services
• Onboard secure element to keep credentials safer during communication

Who is this for? Makers, students, and engineers who need a compact, network-ready microcontroller for connected prototypes will find the MKR WiFi 1010 a strong fit. It’s especially useful when you require both WiFi and Bluetooth on the same board, more flash memory than basic boards offer, and straightforward Arduino IDE compatibility for fast development cycles.
