Finally Merlins Glassbower has been given a new PCB without VU-meter – which was making way too much noise when switching the LEDs despite the chip beeing a low noise version.
Its version 1.5 now. If you want to build a boost 27dB without OpAmps check it out here: Merlins Glassblower V1.5 PCB
The ROG Umble board has been verified to be workiing with the SMD JEFT versions. No more searching for the discontinued parts. Check it out here: ROG Umble V1.4 PCB
