• 嘉立创 EDA 设计https://pro.lceda.cn/
• 嘉立创 投片生产．https://www.jlc.com/

• JP2 , JP16
1-2 5V
2-3 3.3V
*JP2 : MCU + CH340K VCC
JP16: CH340K V3 *

• 不可热插入
• JP2 & JP16 必须成对使用!

• SW4 为常闭开关(NC), 刻录时用
• 焊接时 U4 优先 (1117-3.3V)
• J9/J10 OPEN -> USART TTL-2-USB, 外用 (VCC=5V)
• R10 光敏电阻 = 10K


PCB 100mm x 50mm

STC配套刻录软件, 可以设定硬件, 生成代码, 挺方便的!
最近不搞测试了, 不然加上 MAX485, 做成节点, 4个 DIO/ Relay Board, 还可以．
搞了 20多个, 没想出能用来做甚么? 暂时先打包, 冰起来．

<笔记>天才脑袋比不上烂笔头, 写给自己看, 自用资料。
