freehelot Yes, tested working on debian 11 both on USB, bluetooth and Wi-Fi dongle included. Only thing that doesn't work is the software for changing lights and or macros, you'd have to find another software for that or simply use wine or windows machine to setup your preferences. They are memorized on the keyboard itself. I use it daily to switch between work laptop and my PC instead of using KVM switch.

freehelot Voltage is their rated voltage, meaning maximum voltage allowed to pass through before they blow out.Only way you can change that is changing the voltage passed to capacitors.Considering capacitor wiring, you should read some electronics books or repeat high school physics before doing anything, but for short:Parallel connection: Ctotal = C1 C2 .... CnSerial connection: 1 div Ctotal = (1 div C1) (1 div C2) ... (1 div Cn)Had to replace division symbol with "div" since bg doesn't allow that symbol.

freehelot I had bluetooth speakers and wired connected to it at the same time. There is a switch on the device where you select what mode of operation you want, it's all in the manual and the description.

freehelot It has some neat feature to track your sleep cycles if you want to see that. I personally like the alarm in the morning, as if someone is gently pulling on my hand, less stressful then full pledged alarm. If you don't use the Band alarm or are not interested in sleep cycles that will automatically log your sleep hours, you can always do it manually by logging sleep times.

freehelot It doesn't have gps If you want GPS features when you're walking or exercising, you'll have to turn on Bluetooth, keep it connected to Mi Fit and turn on GPS on your mobile phone. Tested working on Mi Band 4 and 6.

freehelot The body is only available in black. Strap can be bought in 6 colors supported by Xiaomi, or you could find more belt colors and variations on other sites like Ali.

freehelot Any bluetooth capable headphones should work with this device. I see the sony ones have BL V5.0 so in general it should work as others have shown that other bluetooth headphones work. For pairing information I suggest you read the manual for the headphones on how to pair.

freehelot If you meant latency, I haven't noticed any when connected between speakers and my pc, nor in bluetooth. I do have to mention I don't have the tools to measure latency (there is probably some negligible) but you probably can't hear it.
