mCookie-Hub is designed for ease of the connection between Microduino Sensor Series and the core modules on the UPIN27 base board as well as further extended experiment.


Features

  • Integrate twelve sensor interfaces;
  • Small size with sensor interface integrated on the Upin 27 base board;
  • All function pins are extended;
  • Prevent reverse sensor connection
  • Uses 4 pin, 1.25mm pitch JST headers

Specification

  • All mCookie function pins are connected to the base board of the Hub, including digital, analog, serial port and IIC interface.
  • Hub's interface pinout per header: GND, VCC, GPIO-A and GPIO-B.
  • Two IIC interfaces.
  • Uses 4 pin, 1.25mm pitch JST headers / connectors.

Pin Description

Most sensors / trinkets use the first signal (SIGNAL-A) when connecting to the sensor hub.


Hub to Sensor / Trinket Connection Mapping
Hub Header Sensor / Trinket's Connector
GND ( - ) (PIN1) GND
VCC ( + ) (PIN2) VCC
GPIO-A (PIN3) SIGNAL-A -- INPUT / OUTPUT (usually)
GPIO-B (PIN4) SIGNAL-B -- Not connected (usually)

  • Therefore, when referencing the sensor / trinket in code. Use the first number (GPIO-A) on the labeled header. See examples below.
  • Some modules use both signals A & B, but they are limited.
  • Please refer to the specific sensor / trinket page for more detailed information on a specific one.
  • In order to use the second signal. An IO splitter is used to split the signals out into two seperate connectors. More can be read about the IO splitter: IO Splitter
  • IIC (I2C) uses both signals, but these headers are strictly for IIC communication.

Example

  • With a Light Sensor that is plugged into the A2/A3 header. Use A2 to access the light sensor. (On the A2/A3 header: GPIO-A=A2; GPIO-B=A3)
  • With an Single Color LED that is plugged into the 6/7 header. Use 6 to control the LED. (On the 6/7 header: GPIO-A=6; GPIO-B=7)

Each sensor / trinket page has more specific details to which pins are used, but the general rule is use the first signal (SIGNAL-A).

Each sensor / trinket may require usage of a specific type of pin, such as an analog pin. This information can be found on the wiki page for that specific sensor / trinket.
