LCD 8×20 LDS8H1011B

It took me a lot of work to find at least pin outs for LCD 8×20. Seems tipical, but it doesn’t. Maybe info below will be useful.

Display description contains ALPS NEA02028AA and LDS8H1011B and chip M50530. The rest is in Mitsubishi M50530-XXXFP data sheet – LCD controller-driver. Here.
