Hardware Description

Overview

The Top and Bottom Assembly views of the RYZ014AAA are represented in Figure 17 and Figure 18.

Power Supplies

RYZ014AAA has two power domains:

1. One power domain for the entire auxiliary and debug circuitry (AUX).
2. One power domain for the LTE modem (CORE).
   

The auxiliary power domain can only be powered via USB.
The LTE modem can be powered in three different ways: USB, VBAT_IN, VBAT_CORE.

• USB
  When USB is connected and no other voltage is applied to the board, a regulator generates 3.3V_AUX which is used to power the LTE modem

• VBAT_IN
  VBAT_IN is available on J4 connector and on pin 2 on connector P3. VBAT_IN must respect the voltage range defined by the module in RYZ014AAA board. When VBAT_IN is above 1.6V, the module power VBAT_CORE is automatically switched from the 3V3_AUX to the VBAT_IN supply.

Note: When powering the LTE module via VBAT_IN, there is some extra leakage on the power supply circuitry itself as per Table 2. Therefore, it is not recommended to use this power supply when measuring the LTE module rock bottom current.

Table 2. Power Leakage if Power by VBAT_IN

See also Section 3.1, How to Connect an External Power Supply on page 11

• VBAT_CORE
  The module VBAT_CORE is available on ST3 jumper. By disconnecting ST3 jumper, the LTE module can be powered directly with an external supply. This setup is recommended when measuring the module’s rock bottom

See also Section 3.2, How to Connect a Series Current Meter on page 12.

Power-On and Reset

RYZ014AAA has two buttons to control power and reset:

• Reset push button (S1): resets the module when pressed.
• Power toggle button (S2): cuts USB power ON/OFF

USB Port and UART Switches

RYZ014AAA provides access to all the LTE modem UARTs via the USB connector. Each individual UART can be redirected to the expansion connector via the S3 switch. When the switch is in “UART” position the UARTs are redirected to the USB port:

SIM Card

RYZ014AAA supports connectivity from a MFF2 SIM (U11) or from a SIM slot (J6). Both solutions connect to RYZ014A SIM0 interface. A multiplexer automatically selects between the embedded MFF2 SIM and the SIM slot as per Figure 13

• When a SIM card is plugged into the push-eject SIM slot (J6), this will be used to connect to the modem
• If a MFF2 SIM is soldered into U11 and the soldering bridge SB10 is configured as OPEN, then on the absence of SIM card in J6, the modem will default to use the SIM soldered into U11.
  

LEDs

Two LEDs are present in the board:

• Power LED (D1): turns on whenever there is USB power
• Activity LED (D2): turns according to network activity if ST2 jumper is fitted and the ACTIVITY LED function is enabled on the module (with AT command AT+SQNLED, please refer to AT Commands Reference Manual for details.)

User Button and Switch

RYZ014AAA board provides a user button (S4) and a u ser switch (S5).

Expansion Connectors

The expansion connectors for RYZ014AAA boards are intended to:

• Allow hardware designers to connect external peripherals for prototyping.

Two expansion connectors are available on RYZ014AAA board. They provide access to all the modem interfaces.

Table 3 provides the correspondence between the expansion connector signals and the module signals.

LTE Antenna and RF Connectors

The EVK features an integrated antenna with a matching circuit. The matching circuit is automatically driven by two of the module GPIOs depending on the operating frequency. In addition, EVK features an RF connector (J1) allowing connecting the board to an external antenna or test equipment. This connector is compatible with Murata® MXHS83QE3000 cable.
Note: When an external antenna is connected on J1 connector, the internal antenna is automatically disconnected.
Alternatively, an SMA connector can also be soldered on J5. This requires also adding a 0Ohm resistor on R57 and removing R54, as shown below:

Default Position for Jumpers and Switches

The below image shows the default position of all jumpers and switches in the board as manufactured by Renesas:

• ST2 and ST3 jumpers are fitted
• S3 is set in “UART” position in order to redirect the UARTs to the USB port

Advanced Functions

How to Connect an External Power Supply

Power via VBAT_IN on J4 Connector

The external power supply can be connected at the Power Input connector J4 (VBAT_IN). When the supply voltage at VBAT_IN is above 1.6V the module power VBAT_CORE is automatically switched from the 3V3_AUX to the VBAT_IN supply.
Note: J4 is a 2-way, 1-row, right angle PCB terminal block header. To connect to J4, a 3.81mm pitch, 2-way PCB terminal block can be used.

Power via VBAT_CORE on ST3 Connector

The external power supply can be connected at the ST3 VBATT_CORE for the module VBAT1 to supply and measure power.

How to Connect a Series Current Meter

Strap ST3 can also be used to connect a Series Current Meter. The module current must be measured from this point otherwise there is a risk of measuring additional current from the host board.
If using a current measuring power supply, then the power should be connected to the strap ST3.

How to Perform a Remote Reset

When using RYZ014AAA on a remote setup, it may be handy to have the means to reset the board remotely via the host PC. For this, RYZ014AAA includes the means to reset via one of the UART1 ports available on the USB connector
To enable remote reset, a 10 kOhm resistor needs to be fitted on R35.

Remote reset is done by toggling the UART1 DTR pin to High-Low-High. This can be done using a TeraTerm script as shown below:

script as shown below:
; change flow control to "none"
setflowctrl 3
; DTR Reset
setdtr 0
pause 1
setdtr 1
pause 1
setdtr 0

This script sets the DTR high for 1 second, and low for 1 second, and then high (to reset the platform).

How to Modify the Board by Soldering Bridges

Caution: The schematics for the current revision of your board should always be checked before changing solder bridges functions.

Table 4. Solder Bridges Identification

Figure 28 shows 2 fitted and 2 not fitted solder bridges.

Solder bridges can be fitted or removed using a single soldering iron to quickly make or break a connection as shown in Figure 29.
