Seeeduino XIAO RP2040 Seeed Studios

DESCRIPTION

XIAO RP2040 is a microcontroller using the Raspberry RP2040 chip. It runs at up to 133MHz, is built with rich interfaces in a tiny thumb size, and fully supports Arduino, MicroPython, and CircuitPython. The onboard interfaces are enough for developing multiple applications.

Like the Seeeduino XIAO, it is a compact board with a wide range of interfaces. The XIAO RP2040 is equipped with the Raspberry RP2040 chip (Dual-core ARM Cortex M0+ @133MHz). Powerful performance and low power, ideal for various wearable and small projects.

Some key features include:

• Powerful MCU: Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz
• Rich on-chip resources: 264KB of SRAM, and 2MB of onboard Flash memory

• Flexible compatibility: Support Micropython/Arduino/CircuitPython
• Easy project operation: Breadboard-friendly & SMD design, no components on the back

• Small size: As small as a thumb(20×17.5mm) for wearable devices and small projects
• Multiple interfaces: 11 digital pins, 4 analogue pins, 11 PWM Pins,1 I2C interface, 1 UART interface, 1 SPI interface, 1 SWD Bonding pad interface

• Broad compatibility: Pins compatible with Seeeduino XIAO and supports Seeeduino XIAO’s Expansion board

In addition to the powerful CPU, the XIAO RP2040 has 2MB of Flash on board. 11 digital pins, 4 analogue pins, 11 PWM Pins,1 I2C interface, 1 UART interface, 1 SPI interface, 1 SWD Bonding pad interface. Some PINs have various functions, moreover, XIAO RP2040 supports the USB Type-C interface which can supply power and download code. 1 Reset button, 1 BOOT button, 1 user-programmable RGB LED, 1 power LED, 2 status indicators, and 1 user LED are on board, allowing developers to debug their code very easily.

The XIAO RP2040 is very compact because all electronic components are soldered on the same board surface, which means you can easily solder the XIAO RP2040 to your own PCB. XIAO RP2040 is pin-compatible with Seeeduino XIAO, so XIAO RP2040 can be learned and developed using the Expansion board of Seeeduino XIAO

The XIAO RP2040 fully supports C/C++ and MicroPython because it uses the same chip (RP2040) as the Seeed RP2040 Microcontroller family. You can also use the Thonny editor to program as if you were using Raspberry Pi Pico

Please Note: 

• All the I/O pins are 3.3V, please do not input more than 3.3V, otherwise, the CPU may be damaged.
