【HaaS征文】上新开源HaaS100扩展板
板载硬件资源：
- 24V转12V模块接口 x1
- 12V非隔离开关 x1
- 24V非隔离开关 x1
- 12V/24V可选的隔离继电器 x1
- 兼容SPI和I2C的OLED接口 x1
- 3.5mm音频接口 x1
- 微动按键 x3
- 5.5mmx2.1mm DC接口 x1
- 自恢复保险丝 x1
- 接线柱 x2
- PH2.54插座 x3
注：实物Rev1.2 丝印SCL(I2C)和CLK(SPI)位置错误，应该互换。（项目文件已修复此问题）
正确丝印如下：
注：使用SPI0接口，只需短接CLK和MOSI两处即可。使用I2C需要短接SCL和SDA并焊接I2C上拉电阻R12/R13。
