The ZY12PDN module is a USB Type-C PD (Power Delivery) trigger module. It allows you to access various voltages available through USB Type-C power protocols. Here are some key features:

• Power Delivery Control Chip: Supports multiple power delivery protocols with a maximum power rating of 100W (up to 20V @ 5A).
• Input: USB Type-C (PD) port
• Output Voltages: 5V, 9V, 12V, 15V, and 20V, which can be cycled through using a push button.
• Microcontroller: Typically uses an ST-Micro STM32F030.
• Compatibility: Supports PD2.0 and PD3.0 protocols.
• Size: Approximately 31mm x 15.1mm x 4.3mm.

This module is useful for applications that require different voltage levels from a USB Type-C power source.
