Getting started with WiFi on Raspberry Pi Pico W board

Raspberry Pi Trading announced the Raspberry Pi Pico W board basically based on the same design as the original Raspberry Pi Pico board with RP2040 dual-core Cortex-M0+ microcontroller but adding a wireless module with WiFi 4 and Bluetooth LE 5.2, although the latter is not enabled on the board at this time. The company sent me a sample for review/evaluation, and I’ll focus on the WiFi part since the Raspberry Pi Pico W supports the same MicroPython and C/C++ SDKs as for the Raspberry Pi Pico board plus additional APIs for wireless connectivity. Raspberry Pi Pico W unboxing The board I received was cut from a 480-unit reel, and I also got a one-meter long micro USB to USB cable, which should probably not be included by default for people ordering the $6 board. Just like its predecessor, the board is tiny, and The pinout is the same as the […]

Raspberry Pi Pico W – A $6 Raspberry Pi Pico board with WiFi 4

I was expecting the next official Raspberry Pi board to be either an update of Raspberry Pico with WiFi and Bluetooth or with a machine learning accelerator and the new $6 Raspberry Pi Pico W delivers that wish through the addition of 2.4GHz WiFi 4. Having said that, I was actually expecting a competitor to ESP8266 or ESP32 with a new Raspberry Pi wireless microcontroller, but it did quite happen that way as the Raspberry Pi Pico W features the same Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller found in Raspberry Pi Pico board coupled with an Infineon CYW43439 chip that’s supposed to support both 2.4 GHz WiFi 4 and Bluetooth LE 5.2. Bluetooth is not enabled right now, but may be at a later stage. Raspberry Pi Pico W specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB QSPI flash Connectivity […]

MNT Pocket Reform 7-inch modular mini laptop takes a range of Arm (and FPGA) modules

MNT Pocket Reform is an open-source hardware mini laptop with a 7-inch Full HD display, an ortholinear mechanical keyboard, and trackball, that follows the path of its older and bigger sibling: the MNT Reform 2 laptop initially launched with an NXP i.MX 8M quad-core Arm Cortex-A53 module. The new laptop will not only support a similar “NXP i.MX 8M Plus” module but also a range of other Arm modules namely an NXP Layerscape LS1028A module with up to 16GB RAM, the Raspberry Pi CM4 module via an adapter, Pine64 SOQuartz (RK3566, up to 8GB RAM), as well as based on AMD Xilinx Kintex-7 FPGA for industrial use. MNT Pocket Reform specifications: Available system-on-modules Standard: NXP i.MX 8M Plus quad-core Arm Cortex-A53 @ 1.8GHz with 4 or 8 GB DDR4, Vivante GC7000UL GPU, 2.3 TOPS NPU NXP Layerscape LS1028A dual-core Arm Cortex-A72 with 8 or 16GB DDR4, Vivante GC7000UL GPU Raspberry […]

DevTerm portable Linux terminal now supports Raspberry Pi CM4 via a $19 adapter

DevTerm modular, portable Linux terminal initially designed for modules based on Raspberry Pi CM3 form factor, can now work with Raspberry Pi CM4 for extra performance and memory thanks to a $19 adapter. The Devterm was initially launched in 2020 with a 6.8-inch IPS screen, a keyboard with 67 keys, and a battery module, all connected through the ClockworkPi v3.14 carrier board taking a choice of core modules based on Allwinner H6 or Rockchip RK3399 (now supported in Armbian), besides the Raspberry Pi Compute Module 3 mentioned above. More recently, it also got an Allwinner D1 RISC-V module. The Raspberry Pi CM4 module should bring performance similar to the Rockchip RK3399 module for most tasks, although it may vary a lot depending on workloads, and for regular Raspberry Pi users, software that will be more familiar, and may be better supported. I’ve just a bit surprised it took so long, […]

Iono RP D16 industrial IO module features Raspberry Pi RP2040 MCU

Iono RP D16 industrial IO module Raspberry Pi RP2040

Sfera Labs has launched another Raspberry Pi RP2040-based hardware platform with the Iono RP D16 industrial IO module following the Exo Sense RP multi-sensor module we covered last month. The Iono RP D16 module provides sixteen digital 24V I/O lines, an RS-485 serial interface, a wide range 12-28V power supply input, and its DIN-rail case enables installation in electrical cabinets and automation control systems.

CrowPi L is a $200 laptop shell for Raspberry Pi 4

Two years ago, we reviewed CrowPi 2 Raspberry Pi 4 laptop designed for STEM education with embedded electronics modules and Letscode software with step-by-step tutorials to learn Scratch and Python programming. I found it quite good, but many people were mostly interested in having a Raspberry Pi 4 laptop, and the price tag was a bit high at the time. That’s probably why Elecrow has now designed for CrowPi L laptop shell for Raspberry Pi 4 based on the CrowPi 2 but without all the electronics modules, and with a built-in battery to operate more like an actual laptop. CrowPi L laptop shell specifications: Compatible SBC’s – Raspberry Pi 4 Model B only Storage – Full-size SD card slot Display – 11.6-inch 1366×768 IPS screen (CrowPi 2 was 1920×1080) Video Output – HDMI output for external monitor Camera – 2MP camera Audio – Built-in microphone and stereo speaker; 3.5mm audio […]

Ubuntu Core 22 released for IoT devices and embedded systems

Canonical has just released Ubuntu Core 22, a containerized variant of Ubuntu 22.04 LTS, optimized for IoT devices and embedded systems and supporting Ubuntu’s new real-time kernel. In Ubuntu Core, everything is a snap, including the kernel, OS, and applications both to improve security to sandbox each package and to enable updates of specific packages from the IoT App Store over-the-air (OTA). If something goes wrong during the update, the system will automatically roll back to the previous version, so the device cannot be bricked. The Snap system also minimizes network traffic through delta updates. Ubuntu Core 22 also provides advanced security features with secure boot, full disk encryption, secure recovery, as well as confinement of the OS and applications as discussed above. Customers also benefit from Canonical’s 10 years (until 2032) of security maintenance of kernel, OS, and application-level code, which can be important for deployments in enterprise and […]
