The US082-FS3000EVZ board enables quick
prototyping of the FS3000 mass air velocity sensor
module for a custom system design. The board
provides a standard Pmod Type 6A (Extended I2C)
connection for the onboard sensor to plug into any
MCU evaluation kit with a matching connector.
The US082-FS3000EVZ features Pmod connectors
on both sides of the board allowing additional Type
6/6A boards to be connected in a daisy-chained
solution with multiple sensors on the same MCU
Pmod connector. Because of the standard connector
and software support, the US082-FS3000EVZ is ideal
for the Renesas Quick-Connect IoT to rapidly create
an IoT system.

1. Functional Description
The US082-FS3000EVZ functions as a sensor building block to create a custom system solution. Use the board
individually or with a combination of other sensors by using the Pmod Type 6A interface. For a full list of available
sensor Pmod boards, visit the Quick-Connect IoT website.
2. Setup
2.1 Required or Recommended User Equipment
The following additional lab equipment is recommended for using the board (and is sold separately):
▪Any MCU board that supports Type 6A Pmod.
▪The US082-INTERPEVZ interposer board when using one of the Renesas MCU kits (Tabl e 1).
2.2 Programming Interface
Programming of the system can be accomplished through the Renesas IDE, e2 studio. See the MCU evaluation
kit documentation to set up the initial project in e2 studio. As the project is initialized, adding the FS3000 sensor to
the project takes five steps:
1. Navigate to the file in the FSP Configuration View. In the case shown in Figure 2, select the FS3000 Flow
Sensor.
2. Select the FS3000 Stack and edit the configuration values for your required operation.
3. Click the Generate Code icon and the system generates the code to configure the sensor with the MCU.
4. Sample calls are shown in below in the Example Code showing the function that opens the sensors; similar
calls are required for the I2C bus. Review the manual related to FSP configuration and function APIs for
additional information.
Note: Renesas recommends downloading and reviewing sample projects available on the Renesas website.
5. Use the data in your application.

Example Code to Start the Sensor after Configuration in FSP
/* Quick setup for g_fs3000_sensor0. */
void g_fs3000_sensor0_quick_setup(void)
{
fsp_err_t err;
/* Open fs3000 sensor instance, this must be done before calling any FSXXXX API */
err = g_fs3000_sensor0.p_api->open(g_fs3000_sensor0.p_ctrl, g_fs3000_sensor0.p_cfg);
assert(FSP_SUCCESS == err);
2.3 Software Installation and Usage
Visit the Renesas website for the latest version of the e2 studio and for more information on a full system design,
software development, and the availability of additional hardware.
The minimum FSP version supporting the FS1015 sensor block is FSP 3.8.0. For the latest sensor support, use
the latest release. For the latest connectivity support and details on creating customized IoT system solutions, visit
the Quick-Connect IoT site.
2.4 Kit Hardware Connections
Follow these procedures to set up the kit as shown on Figure 3.
1. Verify that the MCU evaluation kit being used has a Pmod connector set to Type 6A. (For help, see the kit
hardware manual).
a. If no Type 6A Pmod is available, ensure the MCU evaluation kit can use the US082-INTERPEVZ interposer
board and insert the board into the MCU connector before adding any sensor boards.
2. Plug in the US082-FS3000EVZ to the Type 6A connector, being careful to align Pin 1 on the sensor board and
MCU kit.

3. Connect the J4 and J5 jumpers to place 4.7k pull-up resistors on the I2C bus lines.
a. Only one set of pull-up resistors should be used on the I2C bus lines. If multiple sensor boards are used,
only one board should have the jumpers present.
b. MCU kits typically do not have pull-up resistors present on these lines, so make sure to check for them.
4. The sensor is now ready to be used in the system. Follow the MCU kit instructions for connecting and powering
up the evaluation kit.
