SparkFun Blocks for Intel® Edison - GPIO Block

Contributors: CaseyTheRobot

Board Overview

• Level Select - Jumper selects GPIO reference voltage, Can be set to 3.3v or VSYS
• Power Pins - Raw access to power pins on Edison
  • GND - Ground pin for all blocks and Edison
  • VSYS - Raw input for Edison and all Blocks.
  • Normal output (with power blocks) 4.0V-4.1V.
  • You can power an Edison through this pin. Acceptable voltages 3.3V-4.5V
  • 1.8v - 1.8v supplied by Edison internal power supply
  • 3.3v - 3.3v supplied by Edison internal power supply
• General GPIO - Genaral use GPIO pins.
• GPIO/UART1 - GPIO pins that can also be used as a second UART. (Useful for GPS receivers and other serial devices)
• GPIO/PWM - GPIO pins capable of generating PWM waveforms. (Useful for LED dimming and Motor control)
• Expansion Header - The 70-pin Expansion header breaks out the functionality of the Intel Edison. This header also passes signals and power throughout the stack. These function much like an Arduino Shield.
