The RVL Power Management System Version 2 is the ubiquitous power 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. This board is optimized for 4 layer Wii boards, and not designed for use with 6 layer Wii boards that draw substantially more power. NEW FUNCTIONS 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. COOL AND QUIET 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. SMARTER THAN EVER 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. SAFETY FIRST 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. SMALLER AND CLEANER The New PMS is smaller than the original, making it easier than ever to find a nice comfy place to rest in your portable.
