Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SS102010428:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description **[![](https://core-electronics.com.au/attachments/localcontent/3_69772efd2a6.png)](https://www.seeedstudio.com/rp2040.html)** **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. XIAO RP2040 is a development board of the [Seeeduino XIAO](https://www.seeedstudio.com/Seeeduino-XIAO-Arduino-Microcontroller-SAMD21-Cortex-M0+-p-4426.html) series. Like the [Seeeduino XIAO](https://www.seeedstudio.com/Seeeduino-XIAO-Arduino-Microcontroller-SAMD21-Cortex-M0+-p-4426.html), 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. ## **Features** - 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(20x17.5mm) for wearable devices and small projects - Multiple interfaces: 11 digital pins, 4 analog 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](https://www.seeedstudio.com/Seeeduino-XIAO-Expansion-board-p-4746.html) ![](https://core-electronics.com.au/attachments/localcontent/image2_1__42690fdb0e5.png) In addition to the powerful CPU, the XIAO RP2040 has 2MB of Flash on board. 11 digital pins, 4 analog 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](https://www.seeedstudio.com/Seeeduino-XIAO-Arduino-Microcontroller-SAMD21-Cortex-M0+-p-4426.html), so XIAO RP2040 can be learned and developed using the Expansion board of [Seeeduino XIAO](https://www.seeedstudio.com/Seeeduino-XIAO-Arduino-Microcontroller-SAMD21-Cortex-M0+-p-4426.html). ![](https://core-electronics.com.au/attachments/localcontent/file_1445405c551.png) The XIAO RP2040 fully supports C/C++ and MicroPython because it uses the same chip (RP2040) as the [Seeed RP2040 Microcontroller family](https://www.seeedstudio.com/rp2040.html). You can also use the Thonny editor to program as if you were using [Raspberry Pi Pico](https://core-electronics.com.au/raspberry-pi-pico.html) ![](https://core-electronics.com.au/attachments/localcontent/tonny_36091973664.png) **Attention:** All the I/O pins are 3.3V, please do not input more than 3.3V, otherwise, the CPU may be damaged. ## **Specification** - CPU: Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz - Storage: 264KB of SRAM, and 2MB of on-board Flash memory - I/O PINs: 11 digital pins, 4 analog pins, 11 PWM Pins - Interface: 1 I2C interface, 1 UART interface, 1 SPI interface, 1 SWD Bonding pad interface - Power supply and downloading interface: USB Type-C interface - LEDs: 1 user LED, 1 power LED, two LEDs for serial port downloading, 1 RGB LED - button: 1 RESET button, 1 BOOT button - Power Pads: For the battery power supply - Software compatibility: Support Micropython/Arduino/CircuitPython - Projection cover for protecting the circuit - Dimensions: 20x17.5x3.5 mm ## **Application** - Wearable devices - Rapid prototyping (directly attached to the expanded PCB as a minimal system) - Perfect for all the projects need mini Arduino - DIY keyboard - USB development (USB to multi-channel TTL/USB host mode, etc.) ## **Comparison between Seeeduino XIAO and XIAO RP2040** | **Item** | XIAO RP2040 | Seeeduino XIAO | |---|---|---| | **Processor** | Dual-core ARM® Cortex® M0+ @133MHz | ARM® Cortex®-M0+ @48MHz | | **Flash** | 2MB | 256KB | | **Onboard Button** | Reset Button/ Boot Button | No Button(reset pad) | | **RGB LED** | Full-Color RGB LED | None | | **Analog Pin** | 4 | 11 | | **PWM Pin** | 11 | 10 | | **DAC Output** | None | 1 | | **Programming language** | Arduino MicroPython CircuitPython | Arduino CircuitPython | **Hardware Pinout** ![](https://core-electronics.com.au/attachments/localcontent/01_1__56935538547.jpg) ![](https://core-electronics.com.au/attachments/localcontent/XIAO-RP2040-Pin_72597f91c99.jpg) ## **Part List** - 1 x XIAO RP2040 Microcontroller - 2 x 7pins header #### Documentations [XIAO RP2040 Schematic](https://core-electronics.com.au/attachments/localcontent/XIAO_RP2040_v1_12960e9236a.zip) [XIAO RP2040 datasheet](https://core-electronics.com.au/attachments/uploads/rp2040_datasheet.pdf) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_2711.jpg)
