Due to global part shortages, RVL-PMS-2 is out of stock. Lead times for components are extremely long, so it may be several months before we are able to restock. In the mean time, RVL-PMS-Lite can be used in its place.

The RVL Power Management System Version 2 is the ultimate solution for your next Wii portable. This compact board handles all your power needs by combining battery management and voltage regulation onto a single board. Version 2 integrates all the features of the original RVL-PMS, and improves upon them even more. 


Version 2 integrates new functions to improve your portable. Built-in U10 emulation allows the PMS 2 to operate as a replacement for the U10. 


The thermal monitoring has been upgraded to include fan speed controls. The PMS-2 monitors the temperature of your portable through a thermocouple, and adjusts the fan speed accordingly, allowing it to find the sweet spot of cool and quiet. 


Like the first iteration, the RVL-PMS 2 can operate independently of the Wii. But it also has the ability to communicate with the Wii over i2C using custom software, opening a world of versatility. On-screen indicators can display battery level and charging status in game. Using RVLoader on the Wii allows you to configure the PMS 2 right on your portable. You can change your charging parameters, calculate remaining battery life or time to charge, set the power button/switch behavior, monitor internal temperature, update your firmware, and more, all from within software on your portable.


Nobody is perfect, and sometimes a late night session ends with a wire going where it shouldn't. The new built in reverse polarity protection provides a safety net against some of the most common wiring mistakes. While these new protections will not protect you from ALL user error, they might just save you from an unexpected encounter with magic smoke.


The New PMS is smaller than the original, making it easier than ever to find a nice comfy place to rest in your portable. It also features castellated pads along the edges. These pads can be soldered to directly, or soldered wire-free onto boards of your own design using our open-source footprints. Building a tidy, highly integrated portable has never been easier.


Pairing the RVL-PMS with an RVL-PD opens the door to for more features, such as internal flash storage, and USB C Power Delivery for high speed charging. While not required, the two were specifically designed to work seamlessly together to give your portable that professional polish it deserves.
