MinnowBoard:MaxLure-Ika
From MinnowBoard Wiki
The Ika lure is a lure that extends the existing low-speed connection by breaking it out and adding the pieces to make allow the MinnowBoard MAX to interface with an Arduino compatible shield.
Pinout
This details the translation of the pinout from the existing low-speed connector to the Arduino compatible pinout.
- Note: The Analog pins go through a Ti ADS1015
- These pins are accessed via I2C
- Datasheet: http://www.ti.com/lit/ds/sbas473c/sbas473c.pdf
- Note: There are two Ti TXS0108E voltage translators attached to pins 2-13, RX and TX

- NOTE: For Arduino compatible shields to work, all low-speed pins should be set to GPIO except for the I2C interfaces.
- NOTE: If you are going to use PWM, those should be set in firmware appropriately
