Evoluent PCB Upgrade
$50.00 USD
This replacement PCB for the Evoluent VerticalMouse (VM4/VMC/VMD) upgrades its terrible stock sensor with a 1000Hz, gaming grade PMW3360DM.
Installation and configuration instructions are available on Github.
This is slightly more technical than my other producs - it uses the Arduino bootloader, and changing settings involves flashing new firmware to the board. This is pretty easy, but please don't buy if you have 0 technical ability.
