Cytron MOTION 2350 Pro – A Raspberry Pi RP2350 board for robotics and motor control

As mentioned in the Raspberry Pi Pico 2 article, third-party RP2350 boards are already available, and one of them is the MOTION 2350 Pro board from Cytron designed for robotics and motor control. The board features a DC motor driver capable of controlling up to 4 brushed DC motors with voltage ratings from 3.6V to 16V. It also features eight 5V servo ports, eight GPIO ports, and three Maker ports for sensor or actuator modules. Each I/O is matched with its own LED which makes the board ideal for the education market and also simplifies debugging. Finally, a USB 1.1 host port is present to connect peripherals such as the RF dongle for a joystick or a keyboard. Cytron MOTION 2350 Pro specifications: Microcontroller – Raspberry Pi RP2350 CPU – Dual-core Arm Cortex-M33 processor @ 150MHz (RISC-V cores are not mentioned, so they are likely not used at all) Memory […]

$5 Raspberry Pi Pico 2 launched with Raspberry Pi RP2350 dual-core RISC-V or Arm Cortex-M33 microcontroller

The Raspberry Pi Pico 2 is an MCU development board based on the new Raspberry Pi RP2350 dual-core RISC-V or dual-core Cortex-M33 microcontroller with 520 KB on-chip SRAM, a 4MB flash, a micro USB port for power and programming and the same GPIO headers as the Raspberry Pi Pico board with an RP2040 dual-core Cortex-M0+ microcontroller with 264KB SRAM. The RP2350 embeds both an open-source Hazard3 RISC-V dual-core CPU and a dual-core Cortex-M33, but only one cluster can be used at a given time. Apart from the faster MCU cores and higher SRAM capacity, the RP2350 is about the same as the RP2040, albeit it also adds one extra PIO block bringing the total to three. One important new feature is built-in security when using Arm Cortex-M33 cores with Trustzone and other security features. Raspberry Pi RP2350 microcontroller Let’s have a closer look at the RP2350 microcontroller, before checking out […]

Arduino to switch from Arm Mbed to Zephyr RTOS

Following Arm’s decision to stop supporting Mbed from July 2026 onwards, Arduino has now decided to use Zephyr RTOS instead of Arm Mbed for Arduino boards that rely on the latter including Arduino GIGA, Arduino Nano 33 BLE, Arduino Nano RP2040 Connect, as well as Arduino PRO boards/solutions such as the Portenta, Nicla, and Opta families. Note that Arduino UNO, MKR, and Nano families are not impacted by the change since their Arduino Core implementation does not rely on Mbed. The change is not going to happen overnight as software development takes time, and Arduino plans to release the first beta based on ZephyrOS by the end of 2024. and a rollout for various boards starting in 2025 long before Arm Mbed is phased out for good. Arduino is not new to the Zephyr project as the company became a Silver member last year, and they were aware that Arm […]

Raspberry Pi RP2040-based Pico Video4 display board features 4 composite video outputs

The Pico Video4 Display is a Raspberry Pi RP2040-powered board that supports up to 4 analog composite video display interfaces with dedicated frame buffer memory accessible via SPI. The four video outputs are sent out through an RCA connector and a VGA DB15-HD connector that uses the red, green, and blue channels to create a composite video signal. The Pico Video4 Display is based on the Raspberry Pi RP2040 microcontroller chip and the VLSI VS23S040 four-megabit static RAM device with a video display controller that can output NTSC, PAL, and VGA video from the memory array. It provides the composite video outputs with a dedicated frame buffer and other hardware. This ensures that the RP2040’s limited processing power and memory are not hogged up in generating the video signal, leaving room for other major tasks. It has 8 inputs that are voltage-compatible to the input voltage, from 5V to 12 […]

Radxa X4 low-cost, credit card-sized Intel N100 SBC goes for $60 and up

Radxa X4 is a credit card-sized Intel Processor N100 single board computer (SBC) that costs almost the same as a Raspberry Pi 5 with the 4GB RAM model going for about $60 and the 8GB RAM variant around $80. The x86 SBC offers many of the same features as the Raspberry Pi 5 including dual micro HDMI output, four USB 3.2/2.0 ports, Ethernet and WiFi networking, and the 40-pin GPIO header handled through a Raspberry Pi RP2040 microcontroller. Networking is better with 2.5GbE and WiFi 6, M.2 SSD support is built-in and four to eight times faster compared to PCIe HAT for the Pi 5, and the USB 3.2 ports are capable of 10 Gbps speed. So let’s little not too like, and the main downside is the lack of MIPI CSI and DSI connectors for projects requiring those camera and display interfaces. Radxa X4 specifications: SoC – Intel Processor […]

The Pico Display Base Board offers a simpler way to create Raspberry Pi Pico LCD projects

The Pico Display Base Board is a printed circuit board from Applying Microcontroller Solutions that provides a platform for building Raspberry Pi Pico-based display projects. It works with a Raspberry Pi Pico board and an LCD screen based on the Solomon Systech SSD1963 display controller. The Pico Display Base Board features a 40-pin header (Display Port) which connects to GPIO on the Pico to provide an 8-bit parallel interface for the display and SPI pins for the touchscreen and integrated SD card. It supports various display sizes from 4.3 inches up to 7 inches. Displays up to five inches can be powered directly by the Pico. A jumper block on the board can be used to pass power to the LCD and wire the display’s optional flash chip to the Pico. A USB-C port on the board can provide an alternative power source for larger displays. It also has male […]
