Do you have the FRDM-A-S32K358 Arduino shield?

SSSkkkmolea — Thu, 04 Jun 2026 04:30:27 GMT

I am planning to buy the FRDM-A-S32K358, but there are no datasheets or schematics available. I would like to know if an Arduino shield is available, if it has fewer pins than the S32k3X8EVB-Q289, or if there are significant hardware differences between the boards themselves. Are there no schematic diagrams available? Or perhaps a DSN file?

Hello,

1. Arduino Compatibility
The FRDM-A-S32K358 is part of the NXP FRDM Automotive ecosystem and is designed with ease of prototyping in mind.

The board provides Arduino-compatible headers, enabling the use of standard Arduino shields for rapid application development.

For reference, the S32K3X8EVB-Q289 evaluation board also supports an Arduino-compatible pin layout.

2. Pin Availability

It is important to distinguish between:

MCU capability (S32K358 device) vs.
Accessible pins on the evaluation board

While the S32K358 MCU supports a high number of GPIOs (depending on package)

The S32K3X8EVB-Q289 is a full evaluation board providing broad access to MCU pins through multiple connectors and expansion interfaces.
The FRDM-A-S32K358, by design, is a compact and cost-optimized board, and therefore exposes a reduced subset of pins, primarily through Arduino-compatible headers.

As a result, not all MCU pins or peripheral signals are available externally on the FRDM board.

3. Hardware Differences Between FRDM and EVB

The two boards target different use cases:

FRDM-A-S32K358

Compact, low-cost
Rapid prototyping, software development
Arduino shields

S32K3X8EVB-Q289

Full evaluation platform
Full hardware evaluation and validation
Arduino + additional connectors and interfaces

The S32K3X8EVB-Q289 typically integrates a broader range of external interfaces, connectors, and measurement capabilities, making it more suitable for detailed hardware evaluation and system validation.

4. Schematics and Design Files

The product is relatively new and I do not see any dedicated documentation here on the public web page.

You can either wait for update of the page or request it by NXP support ticket at NXP.com.

Best regards,

Peter

For S32K358, there are 3 types of demo board on the official website as below, which one you are talking about?

RD-K358BMU RD-BESSK358BMU EVBMA6X02BMU

It seems there are no arduino connector

Hello,

S32K3X8EVB-Q289

https://www.nxp.com/design/design-center/development-boards-and-designs/S32K3X8EVB-Q289

The boards you listed are not equivalent general-purpose evaluation boards, but rather application-specific reference designs focused on battery management systems (BMS).

As I have express in the post above.

Best regards,

Peter
