DUDE the artwork came out absolutely perfect, I’m so pumped

Those are 0.2mm drill / 0.3mm pad vias! The 3 pads at the bottom are for flashing the ATTiny w/ a pogo flasher.

TL;DR - assembled a wundervolt today, but a bug in the design means I need to make another revision. --- Update time! My inductors arrived from DigiKey this week, and so I had everything I needed to assemble a board. It was first time assembling a board with BGA components and it turned out...

This is really cool!! Thanks for sharing your design. The era of stacked PCBs is here...

Dude this is stunning!

+1 on a cheapo CH341A-based device, I use Heads up that flashrom works on linux, windows, and macOS. I use it on macOS.

I'm really excited about this board. Apart from the features Yveltal pointed out, here's what I'm pumped about: Having battery management on a separate board arguably enables more flexibility and modularity: You can use Thundervolt on both Wii micros and portables You can use different...

Quick update, the boards arrived at the end of January and look great! I'm going to try to assemble one soon, but I forgot to order the inductors in my last DigiKey order - so have to wait for those. In the mean time I've written some basic firmware and an I2C driver for the LP8758. Still...

The ATtiny1616 (and all tinyAVR 0/1/2 series MCUs) is programmed via UPDI. I use a 3-pin handheld pogo probe connected to a SerialUPDI programmer.

Yes! The firmware is on the GitHub repo and handles the power on/off logic and the addressable LEDs. The three pads above U8 are for flashing the compiled firmware:

What sort of framerate are we talking for SkiFree?

It turns out that I'm absolutely terrible at keeping a worklog updated as I build! I'm working on a cutting edge post right now, but figured I'd do one last worklog post that contains the fun stuff I forgot to post along the way. Back in January I ordered my first revision boards. Assembly was...

The wii system menu only works if you have relocated Bluetooth. Is this on a trimmed board without Bluetooth?
