没看懂啊~~~有使用的视频不？

没看懂？要视频？没这么复杂吧。就是一个最小系统，TQFP32的不要焊接罢了。
“直接烧AVR意义似乎有限，毕竟AVR离开外围电路似乎工作也会有问题”这句话倒是没看懂。哪个MCU离开外围电路工作会没有问题？
拿Arduino搞些小开发很方便，但有时想做个独立的作品出来，放一个Arduino的板子又不太合适，例如面积体积有限制等，还是需要直接使用芯片。但是芯片首先需要烧Arduino的bootloader进去，成品板上最多放个下载Sketch的连接器（4~5根线）用于更新，不太会在成品板上烧bootloader的。这个主要就是烧bootloader用的。用的时候接好线，把TQFP32的ATMEGA328或168芯片直接放在中间的焊盘上用手按住，把作为编程器的Arduino板子插上USB口，就能利用Arduino as ISP来烧写bootloader了。
烧写成功后的提示信息（例）：
