 +======Another WIO unit ======
 +
 +This clock uses large Kingbright SA40-19 displays.\\
 +100mm is a size which is visable from a large distance, useful for most Railroad layouts as a wall mount system clock.\\
 +In connection (WIFI) with Rocrail, it can display the same time as the (fast) clock on screen.\\
 +But without connection to Rocrail, it will function as a normal time display.\\
 +The system is using the same pcboard for every display, each configured to where it is used for.\\
 +Only one Lolin module should be installed and two PCA9622 chips on a small board control the displays and their intensity.\\
 +When functioning als standard clock, it collects its time via Wifi from Internet (Frankfurt).\\
 +More to come......\\
