+## RP2040 ZERO
++ RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom.
++ Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz.
++ 264KB of SRAM, and 2MB of on-board Flash memory.
++ USB-C connector, keeps it up to date, easier to use.
++ The castellated module allows soldering direct to carrier boards.
++ USB 1.1 with device and host support.
++ Low-power sleep and dormant modes.
++ Drag-and-drop programming using mass storage over USB.
++ 29 × multi-function GPIO pins (20× via edge pinout, others via solder points).
++ 2 × SPI, 2 × I2C, 2 × UART, 4 × 12-bit ADC, 16 × controllable PWM channels.
++ Accurate clock and timer on-chip.
++ Temperature sensor.
++ Accelerated floating-point libraries on-chip.
++ Programmable I/O (PIO) state machines for custom peripheral support.
