Overview

The Pico2-SPE is a small, low-cost, versatile boards from KWS Computersysteme Gmbh. They are equipped with an RP2350a SoC, an on-board LED, a USB connector, an SWD interface. The Pico2-SPE additionally contains an Microchip LAN8651 10Base-T1S module. The USB bootloader allows the ability to flash without any adapter, in a drag-and-drop manner. It is also possible to flash and debug the boards with their SWD interface, using an external adapter.

Hardware

  • Dual Cortex-M33 or Hazard3 processors at up to 150MHz

  • 520KB of SRAM, and 4MB of on-board flash memory

  • USB 1.1 with device and host support

  • Low-power sleep and dormant modes

  • Drag-and-drop programming using mass storage over USB

  • 26 multi-function GPIO pins including 3 that can be used for ADC

  • 1 SPI, 2 I2C, 2 UART, 3 12-bit 500ksps Analogue to Digital - Converter (ADC), 24 controllable PWM channels

  • 2 Timer with 4 alarms, 1 AON Timer

  • Temperature sensor

  • Microchip LAN8651 10Base-T1S

  • 3 Programmable IO (PIO) blocks, 12 state machines total for custom peripheral support

    • Flexible, user-programmable high-speed IO
    • Can emulate interfaces such as SD Card and VGA

Supported Features

Connections and IOs

The default pin mapping is unchanged from the Pico-SPE.

Programming and Debugging

.. zephyr:board-supported-runners::

As with the Pico-SPE, the SWD interface can be used to program and debug the device, e.g. using OpenOCD with the Raspberry Pi Debug Probe <https://www.raspberrypi.com/documentation/microcontrollers/debug-probe.html>_ .

The overall explanation regarding flashing and debugging is the same as for :zephyr:board:rpi_pico. Refer to :ref:rpi_pico_programming_and_debugging for more information. N.b. OpenOCD support requires using Raspberry Pi's forked version of OpenOCD.

Below is an example of building and flashing the :zephyr:code-sample:blinky application.
