= Purpose of this Wiki Page =

This page documents the AFE-TPL0401-MVK evaluation module designed for use with the Modular and Versatile Reference Kit (MAVRK). The AFE-TPL0401-MVK module provides a quick and simple way to interface with the port expanders, digital potentiometers, and LED controllers mounted on the board. Additionally, the on-board devices use I2C and single-wire communication, and thus can be used to evaluate the functionality of these bus protocols.

= EVM Overview= This section contains general information pertinent to this module.

EVM Description
The AFE-TPL0401-MVK provides a platform to evaluate the performance of TI port expanders, digital potentiometers, and LED controllers. These devices interface using I2C and single-wire buses, and are used to control LEDs and an op amp mounted on the board. Switches mounted on the board can be used to receive user input, and shorting jumpers are used configure device inputs. Various test points are provided for easy access and debugging of internal signals.

Power Requirements
The AFE-TPL0401-MVK can be connected to a MB-PRO-MVK MAVRK Module through any of the AFE slots. All power (3.3 V and 5.5 V) is provided by the motherboard through the AFE connectors.

Getting Started: Configuring the EVM
The preferred method of working with this EVM is through a MAVRK Motherboard. The motherboard, along with a MAVRK MCU module, provides the needed power and digital control for this EVM. When used with the MB-PRO-MVK, the AFE-TPL0401-MVK can be used in any of the 4 AFE slots to test both the left and right MCU busses. See the Hardware Design Guide for MAVRK AFE Modules for details on AFE-MCU communication.

EVM Test Points
Available test points are shown in the diagram below, and can easily be attached to with a scope or multimeter probe. Ground test points are colored black, and a ground pad is available in the bottom right corner for attaching probe ground leads.



EVM Switches, Jumpers, and Headers
The AFE-TPL0401-MVK contains fours switches, three jumpers and a header which can be used to modify the EVM operation. The table below describes their functionality.

Their locations on the board are shown below.



EVM LEDS
