Prototype Board Revisions

Rev1

• Designed by: @mozzwald
• Consisted of protoboard, wire-jumpered parts, SIO cable connected via header pins. * White tick indicates pin 1.
• NodeMCU 1.0 sits on top
• Cable prone to breakage
• While it wasn't explicitly designed to pull power from SIO, mine seemed to (Thom)
• Retired when I got Mozz's rev2.

Rev2

• Designed by: @mozzwald
• SMD board
• NodeMCU 1.0 sits on top
• First iteration of surface mount SIO connector
• Required external USB power
• Saw heavy usage during initial test development
• Still in use

Rev3

• Designed by: @a8bit
• SMD board
• NodeMCU 1.0 sits on top
• Second iteration of surface mount SIO connector, much more chamfering
• Can work on either SIO or USB power
• Still in use
• Contains pass-through for connecting SIO cable.
