Waveshare RP2040-Tiny compact size by doing away with USB and buttons

Waveshare has announced an ultra-compact microcontroller board based on CNX Software's Raspberry Pi RP2040 microcontroller without sacrificing usability by moving the buttons and USB Type-C connector to a removable daughterboard.

The Waveshare RP2040-Tiny board measures 18×23.5mm. The Raspberry Pi RP2040 microcontroller consists of two Arm Cortex-M0+ cores running at 133MHz, 264KB of static RAM (SRAM) and 2MB of off-chip flash memory. There is also a general purpose input/output (GPIO) port on the board. The daughter board has missing buttons and a USB Type-C connector.

The RP2040-Tiny has access to all four analog-to-digital converter (ADC) pins, 16 pulse width modulation (PWM) channels, two SPI, two I2C and two UART buses, an on-board clock and temperature sensor, and even has room for an RGB LED.

The RP2040-Tiny is available now from the Waveshare store for $4.49.
