It includes information about how the module functions and how to use the board. Schematics and layout documentation are also included. 1 EVM Overview The RF-TCA8418-MVK module provides I2C access to a keypad and joystick with select. The module is compatible with any Modular and Versatile Reference Kit (MAVRK) motherboard with an open RF slot. The RF slot is designed for communications and as an input interface between the MAVRK motherboard and a PC, external components, or users. This module connects to the motherboard's RF port. For a full list of RF pinouts with description please see the RF Pinout for MAVRK wiki page. 1.1 EVM Description Figure 1. RF-TCA8418-MVK MAVRK Module The RF-TCA8418-MVK Module provides row/column scanning of: • Twelve (12) switch keypad with press and release detect. • A four (4) position joystick (Up, Down, Right, Left) plus a push to select function. TCA8418 features highlighted by this MAVRK module include: • Last ten (10) keystroke storage. • Keylock and Unlock functionality. 1.2 Highlighted Products • • TCA8418 I2C Controlled Keypad Scan IC TS5A2066 Dual-Channel 10-Ohm SPST Analog Switch SLAU383 – December 2011 Submit Documentation Feedback RF-TCA8418-MVK MAVRK Module Copyright © 2011, Texas Instruments Incorporated 5 EVM Overview 1.3 www.ti.com Block Diagram Figure 2.

The RF-TCA8418-MVK module can operate over the voltage range of 1.65V to 3.65V DC with a typical current draw of less than 1mA. 2.2 Getting Started: Configuring the EVM Configuring the RF-TCA8418-MVK EVM is as simple as installing it into one (1) of the RF slots on a motherboard, such as the MAVRK Pro Motherboard. Figure 3. RF-TCA8418-MVK Module on the MAVRK Pro Motherboard Note: Most demos and test routines use MAVRK_RF1, but any of the RF slots can be used as long as the changes are noted in the #define of the software. For example, in the TCA8418 demo project, the RIGHT and LEFT are #defined to the MAVRK_RF3 and MAVRK_RF4 slots.

TCA8418 RF Slots Defined in the C Code These definitions are used further in the code for initialization of the module and later for the checking for a key press for that module. Figure 5. TCA8418 RF Slot Definitons Used as C Code Variable Names The default slots of MAVRK_RF3 and MAVRK_RF4 from the demo can be easily changed to, for example, MAVRK_RF1 and MAVRK_RF2 by simply changing the RIGHT (#define RIGHT MAVRK_RF1) and LEFT (#define LEFT MAVRK_RF2). 8 RF-TCA8418-MVK MAVRK Module Copyright © 2011, Texas Instruments Incorporated SLAU383 – December 2011 Submit Documentation Feedback Hardware Description www.ti.com 2.3 EVM Connectors, Fuses, and Switches The RF-TCA8418-MVK EVM has two connectors on the back side of the module that connect it to an RF slot on a motherboard like the MAVRK Pro Motherboard. For a full list of RF pinouts with description please see the RF Pinout for MAVRK wiki page. Figure 6. Back side of the RF-TCA8418-MVK MAVRK Module, showing the RF connectors The RF-TCA8418-MVK EVM consists of twelve (12) momentary switch push buttons and one (1) 8 position navigation switch with a push to select function. The function of 11 of the momentary switches is defined by the 12th switch, the SHIFT switch.

You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees, affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes. 2. You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates, contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard. 3. Since the EVM is not a completed product, it may not meet all applicable regulatory and safety compliance standards which may normally be associated with similar items. You assume full responsibility to determine and/or assure compliance with any such standards and related certifications as may be applicable. You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even if the EVM should fail to perform as described or expected. 6.5.2 Certain Instructions It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60° C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use these EVMs. SLAU383 – December 2011 Submit Documentation Feedback RF-TCA8418-MVK MAVRK Module Copyright © 2011, Texas Instruments Incorporated 17 Important Notices 6.5.3 www.ti.com Agreement to Defend, Indemnify and Hold Harmless You agree to defend, indemnify and hold TI, its licensors and their representatives harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in connection with any use of the EVM that is not in accordance with the terms of the agreement.
