Adafruit ItsyBitsy RP2040
We have ✅ 4 available of the AF-4888 in our Sydney warehouse. An extra 73 units available with a short lead time.
The Adafruit ItsyBitsy RP2040 brings the Raspberry Pi RP2040 to the compact ItsyBitsy form factor. Featuring a dual-core Cortex M0+ running at 125 MHz, 264 KB RAM, and 8 MB of SPI Flash, it packs serious power into a board just 1.4" × 0.7" — perfect for shrinking prototypes into tiny final builds.
The RP2040's unique PIO (Programmable I/O) state machines enable custom hardware-level protocols for NeoPixels, I2S audio, LED matrices, and more — all without using the CPU. Supports CircuitPython, MicroPython, and C/C++ with the Pico SDK.
