Ika Lure
Note: The Ika Lure is no longer available.
The Ika Lure extends the MinnowBoard MAX LSE connection by breaking it out and adding the circuitry needed to interface with an Arduino compatible shield, making the lure electrically Arduino compatible and both 3.3v and 5.5v tolerant (configured via jumpers). This lure was produced by CircuitCo but is no longer available. (Note: Lures are owned and supported by their respective owners and manufactures. The community can only give you best effort support; issues should be taken to the respective manufacturers and designers.)
Pinout
This details the translation of the pinout from the existing LSE connector to the Arduino compatible pinout.
Note: The Analog pins go through a Ti ADS1015 and 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. Datasheet: http://www.ti.com/lit/ds/symlink/txs0108e.pdf

- 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
