PineCone BL602 EVB information and schematics

• Approximate dimensions: 26mm x 43mm
• Board layout:

• PineCone BL602 EVB schematic ver 1.1
  • Note: Current schematic, cc1 and cc2 share one 5.1KOhm resistor. Next schematic design will separate out the cc1 and cc2 has it own 5.1KOhm resistors
• The board uses a CH340 Serial/USB adapter. This chip is commonly used in Arduino-class development boards. It is a full speed (12Mbps) USB interface and has vendor ID 0x1a86 with product ID 0x7523.
