  * Input DC-DC must >6V, MAX is 24V
    * About [Boost Converter](https://www.gadgetronicx.com/5v-12v-dc-boost-converter/) which is a type of Switch-Regulator
      * Vo > Vi -> boost
      * Vo < Vi -> buck
      * Basic concept: DC -> AC -> DC
      * Wide input: ~24V
      * High efficiency: >85%, even 95%
      * High ripple noise (XX~XXX mV)
        * LDO may < 1mV

## About FW of CDCFE-Prototpe

### SPI??
* Seems to have relation with *RBCP*
