SB Components’ Trekko Pico is an open-source, RP2040-powered GPS logger with multi-GNSS support

After the success of their Kickstarter campaign, SB Components has now made the Trekko Pico GPS logger available for pre-order. The Trekko Pico is a small location logger for travelers and outdoor enthusiasts that makes it easy to track routes and record their travels. A Raspberry Pi RP2040 powers the Trekko Pico, providing the programming, connectivity, and data logging functionality. The Quectel GNSS L76K module supports the concurrent reception of GPS, GLONASS (or BeiDou), Galileo, SBAS, and QZSS signals, with 32 tracking and 72 acquisition channels. There is a JST 2-pin connector that can be used to attach an external battery, and the Microchip MCP73831 controller is responsible for battery charging and management. Also, users can slot a coin cell into the holder at the back of the board to power a real-time clock for data backup purposes. Potential applications for the Trekko Pico GPS logger include surveillance, telematics, Geographic […]

Review of Purple Pi OH – A Rockchip RK3566 SBC tested in 2GB/16GB and 4GB/32GB configurations

Review of Purple Pi OH and Purple Pi OH Pro

Hello, I am going to review the Purple Pi OH boards from Wireless-Tag. The Purple Pi OH is a single-board computer (SBC) mechanically compatible with the Raspberry Pi. They are designed for personal mobile Internet devices and AIoT devices, which can be used in various applications, such as tablets, speakers with screens, and lightweight AI applications. The manufacturer sent me two models. The first model is the Purple Pi OH, which is equipped with 2GB of memory and 16GB of storage space and supports 2.4GHz Wi-Fi. The second model is the Purple Pi OH Pro, equipped with 4GB of memory and 32GB of storage space. This board supports both 2.4GHz and 5GHz Wi-Fi. The other components of both devices are almost the same. They are powered by the Rockchip RK3566 chip, which integrates a quad-core Cortex-A55 processor up to 1.8 GHz, a Mali-G52 GPU from Arm for 3D graphics acceleration, […]

Make a Raspberry Pi 5 Game Boy lookalike with the PiBoy DMGx handheld gaming console kit

Experimental Pi’s PiBoy DMGxis is a kit that converts the Raspberry Pi 5 into a handheld gaming console that looks like a Game Boy with a 3.5-inch color display and all the controls found on the original Game Boy. The company has launched several PiBoy portable game console kits for Raspberry Pi SBCs over the years, so the new PiBoy DMGx for the Raspberry Pi 5 should come as no surprise, and the company says it should be able to run emulators for N64, PSP, Dreamcast, Wii, Gamecube, PS2, and others. PiBoy DMGx kit specifications: Supported SBCs – Raspberry Pi 5; with adapters: Raspberry Pi 3 and 4 Storage – MicroSD card slot (11) Display – 3.5-inch display with 640 x 480 resolution (3) Video Output – Micro HDMI port from RPi 5 Audio – Speaker (5), 3.5mm audio jack (7) User inputs – D-Pad (10), analog stick (9), […]

Some Raspberry Pi 5 boards can be overclocked up to 3.14 GHz (and run just fine)

The Raspberry Pi 5 is advertised as a single board computer with a CPU clocked up to 2.4 GHz, but some of the boards can run stably at a higher frequency, and Jeff Geerling found out one of his boards could be overclocked up to 3.14 GHz with no issues when running a stress test. The Raspberry Pi 5 already delivers a two to three-times jump in performance against the previous generation Raspberry Pi 4 SBC when clocked at 2.4 GHz, but some already overclocked their up to 3.0 GHz, and many thought it was the maximum limit. But a recent firmware release proved them wrong, as it turns out some Raspberry Pi 5 boards can boot at 3.2 GHz and run stably at 3.14 GHz with an adequate cooling solution. The voltage was also adjusted in the config.txt to more or less safe settings. Contrary to the photo above, […]

7-inch Raspberry Pi CM4-based industrial HMI offers gigabit Ethernet, RS485 Modbus, digital and analog inputs

NORVI RPI-HMI is an industrial controller with a 7-inch touchscreen screen display powered by a Raspberry Pi CM4 and equipped with a range of interfaces including a gigabit Ethernet RJ45 port, a few USB ports, and several terminal blocks for RS485 (Modbus), digital and analog input, transistor outputs, and 24V DC power input. The new Raspberry Pi CM4-based HMI announcement follows the NORVI ESP32-HMI controller that was launched last December with an ESP32-S3 wireless microcontroller and a 5-inch LCD display with resistive touch. The NORVI RPI-HMI builds on that with a much faster Arm processor, a larger display with a capacitive touchscreen, gigabit Ethernet, and a wider range of I/Os that makes it suitable for various industrial HMI and PLC applications. NORVI RPI-HMI Industrial Controller specifications: SoM – Raspberry Pi CM4 SoC – Broadcom BCM2711 quad-core Cortex-A72 processor with VideoCore GPU System Memory – 1GB, 2GB, 4GB or 8GB LPDDR4-3200 […]

The RP2040 Connectivity Board — An IoT solution combining LTE, Wi-Fi, and BLE into a single platform

iLABs (Invector Labs), a European embedded equipment manufacturer, has released a new device, the RP2040 Connectivity Board, an IoT development board that is based on Raspberry Pi’s signature microcontroller IC, the RP2040. The RP2040 Connectivity Board features key IoT connectivity options such as LTE, Wi-Fi, and BLE (Bluetooth Low Energy). It is compatible with both Arduino and PlatformIO and is designed for professional and hobbyist users with wide-ranging connectivity needs. The SARA-R412M series module from u-blox handles cellular communication (LTE) and can be configured to enable multi-regional coverage in both GSM and LTE-M/NB-IoT radio transmissions. It features a unique and immutable root of trust and supports IoT security as a service. The RP2040 Connectivity Board also includes an Espressif ESP32-C3FN4 chip for Wi-Fi/BLE communication based on a RISC-V microcontroller core and implementing a Wi-Fi subsystem that complies with the IEEE 802.11b/g/n standard and supports various operating modes. The Bluetooth Low […]

The Lark Weather Station works with Arduino, ESP32, micro:bit, Raspberry Pi, and other boards

Lark Weather Station Arduino ESP32 Raspberry Pi

The Lark Weather Station measures wind speed, wind direction, temperature, humidity, and air pressure through a range of sensors and connects to popular development boards such as Arduino UNO, ESP32, BBC micro:bit, Raspberry Pi, or DFRobot Unihiker through I2C or UART. We’ve seen several projects for Internet-connection weather stations that retrieve weather data from the web and display the results locally, but the Lark Weather Station allows the users to get atmospheric data right in his/her current location thanks to its built-in anemometer, wind vane, and built-in sensors, as well as expansion interfaces for additional sensors. Lark Weather Station specifications: Storage – 16MB flash good to store about 160 days of data (when data is recorded once per minute) Sensors Compass Anemometer Wind Speed: 0.5~12m/s Cover to protect the anemometer during storage/transport Wind vane and wind direction shaft to report the wind direction (eight directions) Temperature Range –20~60℃ ±0.2℃ Humidity […]

Arducam KingKong – A Raspberry Pi CM4-based Edge AI camera with global shutter sensor, Myriad X AI accelerator

ArduCam KingKong is a Smart Edge AI camera based on the Raspberry Pi CM4 and system-on-module based on Intel Myriad X AI accelerator that follows the Raspberry Pi 5-powered Arducam PiINSIGHT camera introduced at the beginning of the year. The new product launch aims to provide a complete Raspberry Pi-based camera rather than an accessory for the Raspberry Pi 4/5. Smart cameras built around the Raspberry Pi CM4 are not new as we previously covered the EDATEC ED-AIC2020 IP67-rated industrial AI Edge camera and the StereoPi v2 stereoscopic camera used to create 3D video and 3D depth maps. The ArduCam KingKong adds another option suitable for computer vision applications with an AR0234 global shutter module, PoE support, and a CNC metal enclosure. ArduCam KingKong specifications: SoM – Raspberry Pi Compute Module 4 (CM4) by default CM4104000 Wireless 4GB RAM Lite (0GB eMMC). AI accelerator – Luxonis OAK SOM BW1099 based on Intel […]
