Product description
Adjustable output voltage from USB-C PD, 5 to 20 VDC. The USB PD trigger module EKM024 is developed and manufactured by Electrokit. Based on the well-known USB PD controller HUSB238.
A USB PD trigger is a module used to negotiate a specific voltage from a USB PD (Power Delivery) power adapter, power bank, or charger. A standard USB port normally provides 5 V, while the USB PD standard offers several different voltage levels (typically 5 V, 9 V, 12 V, 15 V, and up to 20 V). The actual voltage available from the USB PD power adapter depends on which levels it supports. Make sure the USB power supply supports 3A for selected output voltage.
The USB PD trigger sends a request according to the USB PD protocol, specifying which voltage the adapter should deliver. If the requested voltage level is not supported, or if the adapter does not support USB PD, the default 5 V will be supplied.
The output voltage is selected by placing a jumper on the included pin header. Alternatively, voltage and current limit can be configured via I²C (Qwiic connector).
Note that a PD-compatible USB power source capable of delivering the desired output voltage is required. The module does not generate its own voltages and can only supply 5 V / 500 mA if the PD negotiation cannot be established.
The module is fully assembled and comes with a screw terminal and pin header that can be soldered in place.
