Arduino Nano RP2040 Connect WiFi & Bluetooth board launched for $25.50

Arduino Nano RP2040 Connect without headers

The Arduino Nano RP2040 Connect board was announced the day of Raspberry Pi Pico launch as one of the third-party boards featuring Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller. At the time all we had was renders of the board, later on, the company showcased some mass product photos, and then released Arduino Core mbed 2.0 for the board last month. But it’s only today that it has become possible to purchase Arduino Nano RP2040 Connect board for $25.50 on Arduino store with headers. Nano RP2040 Connect specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller @ 133 MHz with 264 kB of embedded SRAM Storage – 16MB Flash IC (AT25SF128A) Connectivity – WiFi 4 & Bluetooth LE via Nina W102 uBlox module (Yes, that’s an ESP32 module.) USB – Micro USB port I/Os via 2x 15-pin headers (through and castellated holes) 20x digital I/O pins, 20x PWM pins, 20x […]

Raspberry Pi CM4 based Exo Sense Pi multi-sensor device gets optional earthquake sensor

Sfera Labs’ Exo Sense Pi is a device with multiple environmental sensors based on the 2GB version of the Raspberry Pi CM4 module designed for residential and commercial applications such as environmental monitoring and data gathering, BLE positioning, indoor people and assets tracking, rooms management and access control, voice control, and more. The Exo Sense Pi devices include optional WiFI 5 and Bluetooth 5.0 LE connectivity depending on the RPI CM4 module selected, and ships with temperature, humidity, air quality (VOC), light intensity, microphone, and PIR motion sensors by default, but there’s also an optional earthquake sensor. Exo Sense Pi specifications: SoM – Raspberry Pi CM4 (16GB eMMC flash) or CM4 Lite module with 2GB RAM by default. But obviously compatible with other models. Storage – MicroSD card socket for CM4 Lite module Wireless connectivity – 2.4 GHz, 5.0 GHz IEEE 802.11 b/g/n/ac wireless; Bluetooth 5.0, BLE depending on installed […]

Flashback: This is what the Raspberry Pi USB Computer looked like 10 years ago

The first Raspberry Pi single board computer was officially launched on February 29, 2012. Raspberry Pi Model B included a Broadcom BCM2835 ARM11 processor with 256 RAM, an HDMI port, and the familiar form factor we know today. But the very first time I wrote about the board was on May 8, 2011, exactly ten years ago, with a post entitled “25 USD ARM11 Linux Computer” showing the prototype of Raspberry Pi USB Computer that looks nothing like what was launched the next year. This just looked like a stick with an HDMI port on one hand and a USB port at the other. We did not even know it was based on a Broadcom processor at the time. Those were the preliminary specifications: CPU – 700MHz ARM11 processor GPU – OpenGL ES 2.0 capable Memory – 128MB of SDRAM Storage – SD/MMC/SDIO memory card slot Video & Audio Outputs […]

Z-Pi 7 Z-Wave gateway devkit works with Raspberry Pi and Orange Pi Zero boards

WiFi & Bluetooth are the most popular wireless protocols for home automation, alternatives like Zigbee and Z-wave have also been widely adopted, at least in some countries. And if you are interested in the latter, Aeotec has just introduced the Z-Pi 7 gateway development kit that lets you add Z-Wave connectivity to Raspberry Pi boards or Orange Pi Zero SBC with an expansion board connected over UART through the GPIO header. Aeotec Z-Pi 7 Z-Wave expansion board (ZWA025) specifications: Z-Wave connectivity Silicon Labs EFR32ZG14 Arm Cortex-M4 SoC @ 39 MHz with Series 700 and Gen7 technology Frequencies ZWA025-A: US Frequency 908.42 Mhz ZWA025-B: AU Frequency 921.42 Mhz ZWA025-C: EU frequency 868.42 Mhz TX Power – US: +9.3 dBm; EU: +4.8 dBm RX sensitivity – -97.5 dBm Range Indoor – US: 70+ meters; EU: up to 60 meters Outdoor – Up to 200 meters SmartStart native integration and S2 security.

ClusBerry-2M Industrial IoT controller takes two Raspberry Pi Compute Modules 4

Earlier this year, Techbase introduced the ClusBerry 9500-CM4 cluster system for industrial IoT that can take up to eight Raspberry Pi Compute Modules 4 housed in a DIN rail enclosure. But for smaller projects and IoT prototyping, the company has now designed ClusBerry-2M, a smaller cluster device including two independent ModBerry I/O mainboards and two Compute Module 4’s that’s equivalent to two ModBerry 500-CM4, but with support for software cluster management tools such as Docker and K3s Lightweight Kubernetes. The company did not share the full ClusBerry-2M specifications, but we can derive most of the features from the photos, previous products features, and the announcement: SoM – 2x Raspberry Pi Compute Module 4 with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, up to 32GB eMMC flash. Storage – 2x M.2 slots for NVMe SSDs Video Output – 2x HDMI 2.0 ports Connectivity 4x Gigabit Ethernet […]
