So I’ve learned that the LED lights and LED display that I’ve used in earlier versions of the SV650 ECU Decoder have the unfortunate issue that the LED display is completely washed out in daylight. The LED lights, even though they are 10mm are hard to see as well.

Hence, I’ve redesigned the board around the Nokia 5110 LCD display. These display was originally used in cell phones and being LCD should be easier to see in sunlight. Suzuki even used a LCD display in the OEM dash. The biggest challenge with using a LCD display was finding one which would fit in the existing footprint. I really didn’t want to increase the board size since bigger boards cost more money. The biggest challenge was finding a switch which would fit- in the end, I went with a 6mm switch which *just* fits.

Of course, removing the LED lights and changing the display will require a significant rewrite of the code, but there are good libraries for the Nokia 5110 display so hopefully that won’t be too hard.
