Tested: YZX Studio ZYPDFS PD3.1 140W (28V/5A) USB-C PD Trigger/Decoy Board

The USB-C Power Delivery protocol has made life easier for many devices, being a viable means of providing DC power at a range of voltages and power levels. Standard USB-C PD The YZX is limited to 60W (20V/3A) with cables that have no eMarker and 100W (20V/5A) when used with a compatible cable, this wasn’t quite enough for all devices. High-end laptops, for example, are a notable exception and some proprietary extensions have existed to squeeze a bit more out of it (e.g. Lenovo’s 140W at 20V/7A or even Raspberry Pi’s 25W at 5V/5A). The USB-C PD Extended Power Range (EPR) protocol makes for a standardised way to push the power envelope of PD from 100W up to 240W (48V/5A). This is the basis of the majority of ports on modern chargers that support outputs greater than 100W with 140W being a common tier (28V/5A). As I needed to do some testing of 140W capability, I needed a way to trigger this mode. Conventional trigger boards won’t do and I really didn’t want to have a Fnirsi FNB58…
