Raspberry Pi Pico

树莓派 Pico 和 Pico H
Raspberry Pi Pico 是一款低成本、高性能的微控制器板，具有灵活的数字接口。主要特点包括：

英国Raspberry Pi设计的RP2040微控制器芯片

双核 Arm Cortex M0+ 处理器，灵活的时钟频率高达 133 MHz

264kB SRAM 和 2MB 板载闪存

支持设备和主机的 USB 1.1

低功耗睡眠和休眠模式

使用 USB 大容量存储进行拖放编程

26×多功能 GPIO 管脚

2×SPI、2×I2C、2×UART、3×12位ADC、16×可控PWM通道

精确的片上时钟和定时器

温度感应器 / Temperature sensor

片上加速浮点库

8 个可编程 I/O (PIO) 状态机，用于自定义外设支持

Raspberry Pi Pico 是一个蜂窝状模块，可以直接焊接到载板上，而 Pico H 则带有预焊接头。

https://micropython.org/download/rp2-pico/rp2-pico-latest.uf2

1. macOS Terminal

# 安装
$ brew install minicom

# 连接 
$ minicom -b 115200 -o -D /dev/tty.usbmodem0000000000001

2.3. Connecting from a Mac
