spacemouse enterprise sings

Post by yerdna »

Recently discovered that spacemouse enterprise sings when you dim the LCD.

Looks like the EE that designed the dimming circuit didn't use the right capacitor dielectric on the LCD backlight net...or the CM that builds them did a part swap without thinking too much.
