Sensor HUB module (mCookie)

Regular price $14.00 Sale

Enables easy to use plugging of sensors. 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.

12 slots available. 14 digital I/O, 6 analog I/O, 2 I2C I/O.

Compatible with mCookie series.

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 separate connectors. More can be read about the IO splitter: IO Splitter
  • IIC (I2C) uses both signals, but these headers are strictly for IIC communication.
