Hi All,

I'm helping a friend with his Brewtroller (Pro 4.0) and it looks like we broke his I2CLCD expansion board version 2. Does anyone have a schematic/BOM for that board? (I found Eagle files for the Version 1 board). I replaced the ATMega controller, but it looks like the Y1 Crystal died too. Anyone know what that part is?

Thanks,
Jeff

I don't see a Y1 on my BOMs, but there are I2CLCD boards for preorder if you need one.

I might have to just preorder a board. Does anyone know how to program the old I2CLCD boards? I found a little bit of code on Github, but not even a read me file on how to load it or which arduino build it goes with.

Does anyone have the user guide to the I2CLCD boards?

You would need an AVR programmer to program the I2CLCD board. The Firmware is on the Github. Ideally, you should never need to do that.

I see. My LCD went out and when I probed the back of the board I saw 7.5V on VCC. I replaced the LDO and now have 5V on VCC, but I assume the Mega168 is dead. I bought a new Mega and soldered it on, so now I just need to figure out how to get the code loaded.

You have the I2CLCD boards under preorder, but it says stock of 9. Do you actually have some in stock? I might be better off just buying a new card at this point. I assume it will work with a Brewtroller 4.0.

I am building a limited number of board in this run, hence the stock number. The boards should work fine with a 4.0 brewtroller
