PRODUCTION DATA
The micro-USB connection is the primary communication interface from your PC to the EVM GUI Application. Figure 2-3 illustrates connection associated with communications between the EVM and GUI, as well as firmware programming (some components have been removed from the picture for clarity).
The EZFET_LITE (based on the Texas Instruments MSP430F5528) is programmed at the factory with firmware that implements UART and JTAG over USB.

Table 2-2 describes each communication connection.
| Designator | Description |
|---|---|
| J5 | MSP430 14-pin JTAG interface. Used for programming EZFET_LITE firmware on MSP430F5528 during manufacturing and not used during normal user operation. |
| J6 | Micro-USB interface for main MCU (MSP430G2553). Both UART and JTAG are routed over this connection. |
| J7 | These headers route communications and 3.3V to the main MCU. Jumpers must be installed on 3V3, RX, TX, TDIO, and TCK positions. |
