RP2040-Zero Mini Version is a Pico-like MCU board built around the Raspberry Pi RP2040. This castellated module is designed for direct soldering to carrier boards, making it suitable for SMD applications. Key specifications - RP2040 microcontroller designed by Raspberry Pi (UK): dual-core Arm Cortex-M0+ up to 133 MHz, 264 KB SRAM, 2 MB Flash memory. - Type-C USB connector for USB 1.1 with device and host support. - Low-power sleep and dormant modes for energy-efficient operation. Module and connection details - Castellated module enables direct soldering to carrier boards. - Drag-and-drop programming via mass storage over USB. I/O and peripherals - 29 multi-function GPIOs (20 via edge pinout, others via solder points). - 2 × SPI, 2 × I2C, 2 × UART. - 4 × 12-bit ADC. - 16 × controllable PWM channels. 2-3 practical use scenarios - Compact robotics controller: manage sensors, actuators, and motor feedback with multiple interfaces (SPI, I2C, UART) and PWM outputs in a small form factor. - Sensor hub or data logger: collect data from various sensors through I2C/SPI, read analog signals with ADC, and store or transmit data efficiently. - USB peripheral or development board: leverage drag-and-drop programming via USB for rapid prototyping and testing, with flexible USB connectivity.
