For our friends who are unfamiliar, the Seeeduino XIAO is the smallest Arduino compatible board in the Seeeduino Family. It has a rich interface and tiny size as well as a super low price. Because of this, the Seeeduino XIAO has become popular for use in a variety of maker projects, as well as in classrooms worldwide. We’ve learned quite a bit from the Seeeduino XIAO and are happy to bring you its newest iteration: XIAO RP2040
The XIAO RP2040 has the same dimensions and interface as the Seeeduino XIAO. It also supports Seeeduino XIAO’s Expansion board. You can easily solder it to your PCB board. The difference is that the XIAO RP2040 uses a more powerful RP2040 chip (Dual-core ARM® Cortex® M0+ @133MHz). It has 264KB of SRAM, and 2MB of onboard Flash memory and adds an RGB LED and 2 buttons to make the main control board easier to debug. This tiny board fully supports Arduino, MicroPython, and CircuitPython.
The first batch was sold out within 2 hours after going live, and is now out of stock, with the expected shipping date for the next batch in early October. You can see more details at the bazaar and WIKI.
