Thanks for the feedback everyone. I like the look of the Sifam faders and the option to just take the LEDs out or find dimmer ones seems nice to have. Sounds like there is no issue with the circuit if the LED is removed since that has been recommended.

Anybody have part numbers for these LEDS and something that may be dimmer?
Mine are just generic 2x3x4mm LEDs. I bought 180 of them in 9 colors for $10 from China on eBay. Very easy to replace. Just take the cap off, pull out the LED and replace. No harm done if you get it backwards either (on the replacement LEDs).

Reporting back -- got the F8R module today and it looks really great with less intense LEDs.

I’m really interested in getting one of these. By any chance would anyone know from where I could buy an I2C cable to connect to an ER-301? European vendors preferable

there's nothing special about the cables. These are the same thing I have in the shop

There IS something a little special about the ER-301 Rev07 hardware I2C connection. The SCL and SDA connections on that revision are reversed as compared to most modules. It also requires a diode to be jumpered on the SoC. Neither of those issues are present on the latest Rev10 hardware.

Thanks for the pointer. I’ll make sure to grab a few of these.

My ER-301 is a rev10 model so should be easy to get it working
