RP2 Nano is a $6.6 Raspberry Pi RP2040 board with Arduino Nano form factor

ArtronShop RP2 Nano board features the Raspberry Pi RP2040 microcontroller in the Arduino Nano form factor in a way that’s much cheaper than the official Arduino Nano RP2040 Connect board. That’s possible because Thailand-based AtronShop did not include all the bells and whistles such as WiFi and Bluetooth connectivity, sensors, and used a smaller flash. So the RP2 Nano basically offers the same I/Os and features as the Arduino Nano, but the Microchip ATmega328 8-bit AVR microcontroller gives place to the more powerful Raspberry Pi RP2040 dual-core Cortex-M0+ MCU plus 2MB flash, and the board also adds an extra Grove connector for expansion. RP2 Nano specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller @ 133 MHz with 264 kB of embedded SRAM Storage – 2MB SPI flash USB – 1x USB Type-C OTG port for power, data, and programming Expansion Arduino Nano headers (2x 15-pin headers) Up to […]

ESP32-S3 based Arduino Nano ESP32 board supports Arduino and MicroPython programming

The Arduino Nano ESP32 is an ESP32-S3-based WiFi and Bluetooth microcontroller board designed for IoT applications for hobbyists and enterprise use cases. The new Nano board comes with 8 MB PSRAM and 16 MB flash storage and can be programmed with either the Arduino or MicroPython languages. It’s not the first ESP32 board from Arduino, as the Nano RP2040 Connect pairs a Raspberry Pi RP2040 MCU with an ESP32 module from u-Blox and the just-released Arduino UNO R4 WiFi marries a Renesas RA4M1 Arm Cortex-M33 MCU with an ESP32-S3-MINI-1 module. But the Arduino Nano ESP32 is different since it’s the first ESP32 board from Arduino where the Espressif chip is the only microcontroller onboard and handles both wireless connectivity and GPIOs. Arduino Nano ESP32 specifications: Wireless module – u-Blox NORA-W106-10B with MCU – ESP32-S3 dual-core Xtensa LX7 microcontroller @ up to 240 MHz with vector extensions, 512KB SRAM, 384KB ROM, […]

smolOS brings a Linux-like command line interface to ESP8266 microcontroller

smolOS (pronounced small OS) is an open-source, lightweight MicroPython program that implements a POSIX-style (Linux-like) command line interface for the ESP8266 WiFi microcontroller. Krzysztof Jankowski (w84death) designed smolOS to be easy to use, allowing the listing and removing of files and also including the smolEDitor which, as its name implies, is a simple text editor. There are currently eight commands with the familiar ls, cat, and rm, plus ed to launch the text editor, welcome to show the welcome screen above, cls to clear the screen, mhz to set the processor speed to 80 or 160 MHz, and info to display some hardware and software information. The project looks to be a work in progress, and the developer highlights the editor is at the alpha stage of development, so more features may be implemented over time by Krzysztof himself or by the community of developers. I also assume other microcontrollers […]

Micro RP2040 is a tiny Raspberry Pi RP2040 module with a USB Type-C port, 28 castellated & through holes

SB Components’ Micro RP2040 is a tiny module based on the Raspberry Pi RP2040 Arm microcontroller with up to 23 GPIOs and a USB Type-C port for easy powering and programming. Ever since the Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller was released, companies have been making tiny modules based on it. Some come with a USB Type-C port such as the Pimoroni Tiny 2040 and the Adafruit QT Py RP2040 boards, while others focused on providing a smaller form factor for soldering only with design such as the RP2040 Stamp or the minuscule 12x12mm Femto module. The Micro RP2040 module comes with a USB-C port and more I/Os than competing modules thanks to a slightly larger 25 x 24.95mm design. Micro RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 264kB of SRAM Storage – 2MB QSPI flash USB – USB Type-C […]
