IoTsmart RP2350A: Dual-Architecture Automation Controller

Built for control, not just connectivity — our latest module is engineered around Raspberry Pi's RP2350A microcontroller. This powerful dual-core, dual-architecture MCU isn't just a component; it's the core of a solution engineered to deliver precise, deterministic control for demanding automation tasks.

Discover the power of the IoTsmart RP2350A module, engineered around the advanced Raspberry Pi's RP2350A microcontroller, packing a dual-core and dual-architecture design: dual-core Arm Cortex-M33 processor and dual-core Hazard 3 RISC-V processor, flexible clock running up to 150 MHz, 520KB of SRAM, and 4MB of onboard flash memory. This module is a core component of our modular ecosystem (learn more on our Philosophy page).

Comprehensive examples are actively maintained to help accelerate your project development.

Applications

* Local HMI via EYESPI is only possible with IoTsmart RP2350A version 2-01 and later; not available on 1.xx versions.

Note: Version 2-01 in stock is electrically identical to 2-02 — the only difference is the missing QR code on the bottom-side silkscreen.

Compatible Mezzanines:

• Digital: IoTextra Input, IoTextra Relay2, IoTextra SSR Small, IoTextra MOSFET2, IoTextra Octal, IoTextra Octal2, IoTextra Octal3
• Analog: IoTextra Analog, IoTextra Analog3
• Combo: IoTextra Combo

Unmatched Performance & Capabilities

• Advanced Multi-Core Processor: At its core, the IoTsmart RP2350A features a high-performance dual-core Arm Cortex-M33 processor and a dual-core Hazard 3 RISC-V processor, delivering blazing-fast flexible clock speeds up to an impressive 150 MHz.
• Expanded Memory: Benefit from enhanced application capacity with 520KB of SRAM and a generous 4MB of onboard flash memory.
• Dedicated Data Storage: 8Kbit or 16Kbit EEPROM (M24C08 / AT24C08C or compatible) for robust configuration and user data persistence.

Superior Connectivity & Integration

The IoTsmart RP2350A provides comprehensive connectivity options for complex projects:

• 12-pin HOST Connector: Provides I²C (SDA and SCL), 8 GPIO contacts, and two power contacts (+5V and GND). Choose your installation method:
• TOP (H-HOST) Option: For vertical mounting into your IoTextra series mezzanine.
• BOTTOM (V-HOST) Option: For horizontal mounting into your IoTextra series mezzanine.
• EYESPI Interface (optional): An onboard EYESPI connector adds plug-and-play support for popular LCDs and other displays using a standardized 18-pin FPC cable.
• Dual Qwiic^© Connectors: Two Qwiic^© connectors for I²C communication allow easy daisy-chaining of multiple devices and sensors without the need for additional hubs. I²C pull-up resistors are enabled by default.
• Optional UART Connector: The UART connector is supported but not pre-installed; it must be soldered by the user.

Power & Debugging Essentials

• Input Power: The module operates on a non-isolated +5VDC input power, conveniently supplied via a JST connector.
• Optimal Size: Measuring 47 x 30 mm, this module maintains a compact footprint while delivering superior performance.
• Debugging: For debugging your projects, a Tiny Adaptor Board with Cable is required (please note: this item is not included and must be purchased separately).

Key enhancements in version 2.02 compared to 1.xx versions:

• Optimized Form Factor: The module now measures 47x30 mm, providing better mechanical compatibility and a more seamless fit when docked with IoTextra mezzanines.
• EYESPI Interface: A new onboard EYESPI connector adds plug-and-play support for popular LCDs and other displays using a standardized 18-pin FPC cable.
• Dual Qwiic^© Connectors: The addition of a second Qwiic connector allows for easy daisy-chaining of multiple I²C devices and sensors without the need for additional hubs.

Module size:

Version 2-02 47 x 30 mm.
Version 1.xx 31 x 40 mm.
