Thundervolt Lite is a stylish, highly-integrated open source power hat with software-controlled undervolting for 4-layer Nintendo Wii motherboards. It allows portablizers to reduce their Wii's power consumption and thermal dissipation and is the most compact Wii voltage regulation solution available.
These PCBs have mousebites. You may have to file or sand the nubs off for optimal fitment on the Wii motherboard.
Features:
- 0.8mm 4L rigid PCB — solders directly to 4-layer Wii motherboards
- 55 x 47mm — fits within all but the most extreme trim outlines
- 2.4V to 5.5V input (intended for 1S li-ion or 5V USB-C)
- Highly efficient I2C-controlled buck regulators for 1V, 1.15V, and 1.8V (η > 90%)
- Highly efficient I2C-controlled buck-boost regulator for 3.3V (η > 90%)
- Dynamic undervolting, configurable via Wii homebrew app
- Safe mode solder jumper to force stock voltages
- True open drain Wii power-on reset functionality (aka U10 emulation)
- Onboard TMP1075N for temperature monitoring and emergency overtemp shutdown
Thundervolt Lite is an advanced mod and is not recommended for beginners. See this BitBuilt thread for installation photos.
