Waveshare has introduced the launch of an ultra-compact microcontroller board constructed across the Raspberry Pi RP2040, which achieves an impressively small footprint with out sacrificing usability — by shifting buttons and the USB Sort-C connector to a detachable daughterboard.
The Waveshare RP2040-Tiny improvement board, dropped at our consideration by CNX Software program, delivers on the promise of its identify: the system measures simply 18×23.5mm (round 0.71×0.93″), but it consists of the Raspberry Pi RP2040 microcontroller with dual-core Arm Cortex-M0+ cores working at 133MHz, 264kB of static RAM (SRAM), and 2MB of off-chip flash storage — and consists of 20 general-purpose enter/output (GPIO) pins round three of its edges.

The key to its measurement is that it lacks each reset and boot-selection buttons, and has no USB connector for energy and programming — all nice-to-have options throughout a mission’s improvement course of however which might be sacrificed at deployment to cut back the general footprint. With that in thoughts, the fourth fringe of the RP2040-Tiny features a flat versatile circuit (FFC) cable connector to be used with an elective daughterboard.
The daughterboard is the place you will discover the lacking buttons and a USB Sort-C connector. The thought is easy: use each boards collectively throughout improvement to make it simpler to program the microcontroller and iterate the firmware, then while you’re able to deploy you may lose the daughterboard and energy the principle board through one among its pins.

Regardless of its small measurement, the RP2040-Tiny consists of all the largest and finest options of the RP2040 — together with entry to all 4 analog-to-digital converter (ADC) pins, 16 pulse-width modulation (PWM) channels, two SPI, two I2C, and two UART buses, plus the on-board clock and temperature sensor, and even finds room for a user-addressable RGB LED. The 2 Programmable Enter/Output (PIO) blocks, which allow you to run state machines individually to the 2 Arm cores, are additionally current and proper.
The RP2040-Tiny is now out there on the Waveshare retailer for $4.49 earlier than quantity reductions; including the USB daughterboard and FFC cable will increase the worth to $4.99.
