esp32s_core's Introduction

ESP32S_CORE

一个超小廉价并且尽量保证可以手工焊接的esp32s之类的模块可用的开发板 尺寸2.7x4.88cm 小料基本上都是0603大小的0.1uf,10uf电容和0603 的10k电阻,同时esp32的焊盘选择了较宽的,基本保证有电烙铁就可以了(当然模块底下的地没链接性能不会很好) bom成本(不包括模块)(不包括ch340c接口按键,模块):大概1.3左右 加上ch340c,接口和按键也在3元附近。 至于esp32s模块 可以买全新的也可以选择闲鱼(笑) 通过各种手段压低成本(手焊,闲鱼等等)之后开发板成本可以在8元以下,弥补之前消失的9.9包邮开发板。 A cheap, small, hand solderable solution to use many expressif chip including esp32s2,esp32solo1,(any module with same design)
