CANPico open-source board adds CAN Bus to Raspberry Pi Pico

Canis Labs’ CANPico board adds a CAN bus to the Raspberry Pi Pico. The open-source hardware board can then be used as a CAN adapter connected  to a host computer The company also provides an open-source MicroPython SDK, as well as a pre-built firmware image to quickly make it started, making it possible to easily control or monitor the CAN bus using Python. CANPico specifications: MCU – Raspberry Pi Pico with RP2040 dual-core Cortex-M0+ microcontroller CAN interface through 3-pin terminal block implemented via: Microchip MCP2517/18FD (SPI) CAN controller with 2Kbyte buffer space Microchip MCP2562FD CAN transceiver. Misc Jumpers to connect a standard 120Ω CAN bus termination resistor and for disabling transmit access to the CAN bus 6-pin header for a logic analyzer or oscilloscope to see what’s happening on the bus Dimensions – Approx. 75 x 24mm The MicroPython SDK for CANPico contains two major APIs with CAN and  CANHack.

PICOmputer connects Raspberry Pi Pico to QWERTY keyboard, display, and optional LoRa module

Peter Misenko (aka Bobricius) has found an interesting use case for the Raspberry Pi Pico board with its PICOmputer, a compact terminal with a QWERTY keyboard, a small IPS display, and even footprint for an RFM95 LoRa module that would allow messaging/texting over LoRaWAN. Note the open-source hardware project is only offered as a kit with either the main board only, or the main board plus a gold or silver front panel, all without components, but fully assembled units are out of stock at this time. So read on, if you’re ready for some soldering and even some rework of the PCB, more on that latter. PICOmputer key features and specifications: Compatible with Raspberry Pi Pico board Storage – MicroSD card slot Display – Three types supported: 1.3-inch ST7789 IPS 240×240 display via 12-pin flex cable 1.54-inch ST7789 IPS 240×240 display via 12-pin flex cable ST7789 IPS 240×240 display via […]

New Raspberry Pi PoE+ HAT handles up to 25.5 Watts

The Raspberry Pi Foundation has just announced the Raspberry Pi PoE+ HAT compliant with 802.3at (aka PoE+) and 802.3af standards and support for up to 25.5 Watts input. It will replace the Raspberry Pi PoE HAT introduced in 2018 which was limited to 802.3af standard with a maximum of 15.4 Watts input and will become available around mid-June for $20 plus taxes and shipping. Raspberry Pi PoE+ HAT specifications vs PoE HAT. Besides supporting 802.3at standard with a higher current/more power, the new PoE+ HAT also adds a current sensor and relies on a planar transformer instead of a wire wound transformer with the former being more compact and efficient. The brushless fan is controlled by I2C and helps the processor on the Raspberry Pi 3/4. You may need the latest version of the Raspberry Pi OS for the new PoE+ HAT to work properly. While the Raspberry Pi PoE+ HAT […]

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 […]

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 […]
