Renzo's chaotic list

BUS physical pinout:

PMOD:
  i2c:
        VCC GND SDA SCL
        VCC GND SDA SCL

  GPIO (type 1):
        VCC GND IO  IO  IO  IO

  SPI (type 2):
        VCC GND CLK MISO MOSI SS
  SPI (type 2A):
        VCC GND CLK MISO MOSI SS
        VCC GND xxx xxx  RST  INT

  UART (type 3):
        VCC GND TXD RXD RTS CTS
  UART (type 4):
        VCC GND RTS RXD TXD CTS
  UART (type 4A):
        VCC GND RTS RXD TXD CTS
        VCC GND xxx xxx RST INT

  HBRIDGE (type 5)
        VCC GND SB  SA  EN  DIR
  Dual HBRIDGE (type 6)
        VCC GND EN2 DIR2 EN1 DIR1

JEENODE:
        5V DIO GND 3V3 AIO IRQ
        or:
        5V SDA GND 3V3 SCL IRQ

        (DIO is digital IO, AIO is analog IO, SDA/SCL are i2C signals).

MAKEBLOCK ME boards:
  Red ports (Motors):
        SCL SDA VMOT GND DIO DIO
  Grey port (UART):
        xxx xxx GND VCC TXD RXD
  Dark Grey (Analog):
        ___ ___ GND VCC AIO AIO
  Blue (dual digital)
        ___ ___ GND VCC DIO DIO
  White (i2c)
        SCL SDA GND VCC ___ ___
  Yellow (single digital)
        ___ ___ GND VCC ___ DIO
  (one port can be Analog, single/dual digital, i2c compatible).


Bus Data Link.
  uart/rs232.
    asynchronous,
  1wire Dallas.
    DS18B20 is the only notable/widesread chip using it
  i2c (a.k.a. twi, two wire interface).
    synchronous bus, up to 128 nodes (master + 127).
  spi (serial peripheral interface)
    synchronous bus, 3 wires: clock, miso, mosi
    it needs separate SS (not enable) pins.
  ...i2s, can
