2018-09-06 (Th) Emergency Rotary Keyboard EmerKeyB

A project was created in EasyEDA for the EmerKeyB. Schematics were drawn which included three pull-up resistors, one encoder and three header rows of header pins. The resistors could be left off the board if the 'pinMode(***, INPUT_PULLUP)' line was intact in the code but it didn't cost anything to put the spots there. They were placed on the underside of the board so if clearance becomes problematic, they can be removed or ignored.

Board schematics

The components were arranged so they would mate with the appropriate boards. The support tines of the rotary encoder had to be removed because they would interfere with the data pins. Removing them shouldn't cause any problems since the encoder should be supported by an enclosure rather than the PCB so no stress should translate to the soldered pins.

First, a layout was created and the routing was done. Since the last time EasyEDA was used, local routing became available. This was a huge step since attempts at asking the server to perform routing was often tiresome and fruitless. It worked well.
