I am wondering if this LCD display will work with Brucontrol.   https://www.sunfounder.com/iic-i2c-twi-serial-2004-20x4-lcd-module-shield-for-arduino-uno-mega2560.html

Amazon has it for only $10

here is the link to the wiki http://wiki.sunfounder.cc/index.php?title=I2C_LCD2004

It looks like it could work, but I see a different chip than the one on the Adafruit LCD backback, so I cannot day for certain. You could try it, or st least cross reference the chips to make sure they are conpatible. Sorry!

I ordered one last night, should be here tomorrow and I will test it this weekend.  Both chips have the same I2C address range.  With the sunfounder having a default 0x27 and I think the adafruit being 0x20 so I can just jump A0, A1, and A2 to ground and hope the chip can work with the same library.

I was able to change the address to 0x20 which is the same as the adafruit default.  Unfortunately, the chips are different enough where the adafruit_liquid crystal library won't work.

Sorry... the adafruit one isn't very costly... best to grab one of those.
