esp32-picodk's Introduction

基于ESP32-PicoD4的开源迷你开发板

最近芯片疯狂涨价,ST系列的MCU价格已经上天,所以后面打算以ESP32为项目的主力平台。

实际上ESP32性能比STM32还强不少:

  • 双核架构,主频还高
  • 带WiFi/蓝牙能力(SiP封装内带射频匹配电路)
  • 原生基于FreeRTOS
  • 直接兼容Arduino生态
  • GPIO-Matrix(神器,GPIO互换,PCB Layout友好度拉满)
  • 接口丰富(3个UART、2个I2C、2个SPI、居然还带CAN
  • SiP封装,外围电路极其简洁

最重要的,在芯片价格涨麻了的今天,ESP32只要十多元一片,好家伙我直接推爆好吗。

同时为了方便以后做原型验证,需要用有一个评估板,看了一圈市面上并没有很满意的(连TypeC的都没几个),所以花了一下午自己设计了一个,也开源给大家。

板子设计已打样验证无误,好用记得点星星👇

特性

  • 所有GPIO引出
  • 板载一个MPU6050、一个OLED、一个CAN-PHY芯片、一个USB转串口、一个用户LED、一个用户按键
  • 上面提到的外设芯片都是可以在板子背面通过跳线选择连接GPIO或者断开的,所以不影响GPIO作其他用途
  • 极致迷你尺寸
  • 带配套亚克力外壳(设计中稍后更新)
