The 'old' board is still very popular among our readers, so it's time to give it a facelift :-) We decided to use a different type of LCD mainly because the pinning of the  EA DIPS082 display used in the original design is rather exotic. On this new board, you can hook up any alfanumeric LCD module with a standard 2x8 pin connector, so it's not limited to connecting a 2-lines and 8-characters display.
We had to redesign the PCB and the component placement differs from the 140009 board, but the electronics and functionality of the boards are completely identical, except for the brand/type of the display of course.
The ready-made boards in our shop will be sold with a 2x8 LCD with backlight.
