| ###################################### |
| |
| Overview |
| ******** |
| |
| The UPD301C Basic Sink Application Example Evaluation Kit (EV11L78A) |
| is a low-cost evaluation platform for Microchip's UPD301C Standalone |
| Programmable USB Power Delivery (PD) Controller. This RoHS-compliant |
| evaluation platform comes in a small form factor and adheres to the |
| USB Type-C™ Connector Specification and USB PD 3.0 specification. |
