The EV-MTE-AGILE-900Z board deploys and tests custom applications built with the AgileNet-6T protocol, a subGHz mesh networking solution. The EV-MTE-AGILE-900Z evaluation board is embedded with the EV-MOD-AGILE-900Z board and can be used to develop a wide variety of applications.
The EV-MOD-AGILE-900Z evaluation board contains the ADuCM4050 microcontroller (MCU), an ultra low power, mixed-signal microcontroller system. The MCU provides digital peripheral interfaces such as an I2C interface and multiple serial peripheral interfaces (SPIx where x is the SPI number). The EV-MOD-AGILE-900Z evaluation board also contains the ADF7030 radio, a subGHz radio chip for a variety of applications.
The EV-MTE-AGILE-900Z evaluation board consists of a module portion, the EV-MOD-AGILE-900Z evaluation board, with an MCU processor and radio. There is also a breakoff portion provided that helps in flashing the MCU and provides multiple options to power up the board.

The EV-MTE-AGILE-900Z can be powered on in the following two ways: battery power and external power. Both the battery power and external power sourced can be used with or without the ADP5300 regulator. The ADP5300, the ultra low power step-down regulator, is present on the evaluation board and regulates the power supplied to the MCU and radio. The ADP5300 is configured to supply a constant 3 V output to the ADuCM4050 MCU processor and ADF7030 radio.
Different power configurations can power up the EV-MTE-AGILE-900Z evaluation board. The user can select the powering options by placing jumper shunts on the 1.27 mm headers (P7). The configuration of the jumper shunts for different power options are described in Table 1.

The evaluation board contains a power LED and three GPIO LEDs that are described in the Power section and the GPIO LEDs section.
The power LED (DS4) is lit if the EV-MTE-AGILE-900Z board is powered on.
Three LEDs (DS1, DS2, DS3) are connected to the general-purpose input/output (GPIO) pin of the ADuCM4050 processor. The LEDs are active high and are turned on by writing a 1 to the corresponding GPIO lines. The pin mapping between the GPIOs and LEDs is described in Table 2.
The push-button switch (see Figure 6) determines the boot mode of the ADuCM4050 processor. Table 3 shows the available boot mode settings. By default, the processor boots from the internal flash memory.
The reset push-button resets the ADuCM4050 processor when pressed.
The GPIO push-button is connected to the pin of the ADuCM4050 processor, P2_10.
To enable the user to easily download the firmware to the EV-MTE-AGILE-900Z evaluation board, UART lines are provided to the MCU through 1.27 mm headers. UART lines can also be used to monitor the program execution and to send commands from the PC to the MCU on the EV-MTE-AGILE-900Z board. The pin description of the 1.27 mm P9 header is shown in Table 4.
The RF signal is brought outside of the board through either the on-board MMCX connector (see Figure 6 and Figure 7), or through the castellations (see Figure 6 and Figure 8), depending on the capacitor configuration.
To route the RF signal through the MMCX connector, connect Capacitor C34 as shown in Figure 7, and leave Capacitor C33 unconnected. To route the RF signal to the castellations, Capacitor C33 must be connected and Capacitor C34 must be open (see Figure 8).

From the module portion of the EV-MTE-900Z board, the EV-MOD-AGILE-900Z board (see Figure 9), a total of 51 pins are accessible through castellations to allow the user to develop a wide variety of applications using the EV-MTE-AGILE-900Z evaluation board.
