KS Elektronikdesign is soon to launch the USBpwrMe on Crowd Supply, an adapter that can be used to power USB devices directly from a bench power supply. It supports USB Type-A and Type-C ports, operates from 3 V–20 V, and can perform charge negotiation at 5 V. Both ports can be used simultaneously; however, the campaign notes that only one USB output should be used at max load.
To help prevent damaging something by accident while testing, the adapter includes reverse polarity protection and overvoltage protection. In negotiated mode, the adapter can supply up to 10 W through USB-A and 15 W through USB-C. In pass-through mode, up to 25 W can be supplied through USB-A or 35 W through USB-C. The adapter is compatible with bench supplies with binding post spacing of 19–23 mm, and includes status LEDs.
USBpwrMe has you covered whether you need to troubleshoot a prototype, monitor power consumption, or just power a USB device from your bench supply. The design files of this open-source project will be made available on GitHub before the campaign launches, under the CERN Open Hardware License Version 2 (CERN-OHL-W v2).
