Getting Started with LoRaWAN on SenseCAP K1100 sensor prototype kit (Part 1)

CNXSoft: This getting started guide/review of the SenseCAP K1100 sensor prototype kit is a translation of the original post on CNX Software Thai. The first part of this tutorial describes the kit and shows how to program it with Arduino to get sensor data to a LoRAWAN gateway and display it on Wio Terminal, before processing the data in a private LoRaWAN network using open-source tools such as Grafana. The second part – to be published later – will demonstrate the AI capability of the kit. In the digital era where IoT and big data are more prevalent, a large amount of data is required to be collected through sensors. To enable the digital transformation, SeeedStudio’s SenseCAP K1100 comes with all necessary sensors and equipment including the Wio Terminal, AI Vision Sensor, and a LoRaWAN module. With this plug-and-play platform, makers can easily create DIY sensors for data collection and […]

StarFive VisionFive V1 RISC-V SBC gets Ubuntu 22.04.1 Server image from Canonical

Canonical has been working on RISC-V support for Ubuntu for a while and released Ubuntu 20.04/21.04 64-bit RISC-V images for QEMU and HiFive boards last year. Now the company has released an Ubuntu 22.04.1 Server image for the StarFive VisionFive V1 RISC-V single board computer. While that’s a good development, The VisionFive V1, and other RISC-V platforms, are nowhere close to being Ubuntu-certified hardware, and Canonical posted a note reading “It is an early RISC-V developer access through Ubuntu 22.04.1.” The VisionFive V1 SBC is a pretty good platform for development with a StarFive JH7100 dual-core RISC-V processor, 8GB RAM, Gigabit Ethernet and WiFi connectivity, HDMI output, and four USB 3.0 ports, plus GPIOS headers, and MIPI CSI and DSI connectors. It offers a good middle ground between the high-end (and relatively expensive) HiFive Unmatched mini-ITX motherboard and the low-end Allwinner Nezha single board computer both of which can also […]

MediaTek T830 to power 5G FWA routers and mobile hotspots

MediaTek T830 is a consumer premise equipment (CPE) SoC with a quad-core Cortex-A53 processor, an integrated Sub-6GHz 5G modem, hardware-based network acceleration engines,and optional support for Wi-Fi 6/6E, and son the new WiFi 7. It’s unrelated to the MediaTek Filogic 830 WiFi router SoC and instead, offers an upgrade to the MediaTek T750 5G chipset for higher performance multi-gigabit CPE products, such as fixed wireless access (FWA) routers and mobile hotspots (Mi-Fi) with up to 7 Gbps 5G speeds. MediaTek T830 specifications: CPU – 4x Arm Cortex-A55 cores @ up to 2.2 GHz GPU – Unnamed 3D GPU Networking accelerators MediaTek Network Processing Unit QoS Acceleration and Tunneling Offload Engine for VLAN / PPTP / L2TP / GRE Memory I/F – LPDDR4x / LPDDR5 Storage I/F – nMCP (NAND-based Multi-Chip Package) suggested. SPI, eMMC 5.1, and ONFI (Open NAND Flash Interface) supported Display I/F – MIPI DSI interface for up […]

Elecrow’s Raspberry Pi Pico Advanced Kit ships with 32 electronics modules, 32 project tutorials

We’ve just reviewed the Raspberry Pi 4-powered CrowPi L laptop and Crowtail Starter kit used to teach programming and electronics, but Elecrow has now launched the “Raspberry Pi Pico Advanced Kit” with 32 electronics modules, a smart kit car, and 32 tutorials that should be a more affordable way of teaching electronics and programming. However, it does so in a different way, as instead of using visual programming and Python, the Raspberry Pi Pico Advanced Kit’s lessons rely on MicroPython, and the projects are different with for example parts to build an obstacle avoidance, line tracking, or remote controlled car. Package content: Optional Raspberry Pi Pico board with Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller Breadboards 2x 400 holes solderless breadboards 1x 170 holes solderless breadboard Display modules 1602 LCD display module (Blue) OLED module 4-bit digital LED display module Lights 10x 5mm LEDs in green, red, blue, yellow, and […]

Nordic Semi nRF7002 is a dual-band WiFi 6 companion IC for nRF52, nRF53, and nRF91 wireless chips

Nordic Semiconductor nRF7002 dual-band WiFi 6 companion chip is the first WiFi chip from the company and is designed to add Wi-Fi connectivity to solutions based on nRF52840 and nRF5340 wireless SoCs, and nRF9160 cellular IoT SiP, as well as non-Nordic host microcontrollers. The nRF7002 also adds Wi-Fi-based locationing (SSID sniffing of local Wi-Fi hubs) when used alongside Nordic’s existing products, and the launch means Nordic is now one of the rare companies offering chips for Bluetooth, 802.15.4 (Matter/Thread), Wi-Fi, and cellular IoT (NB-IoT, LTE Cat M). This was made possible with the acquisition of the development team, core Wi-Fi expertise, and Wi-Fi IP assets of Imagination Technologies Group in 2020. Nordic Semi nRF7002 key features specifications: Complies with 802.11a/b/g/n/ac/ax 2.4 GHz and 5 GHz dual-band Wi-Fi 6 Station (STA) 1 Spatial Stream (SS) 20 MHz channel bandwidth 64 QAM (MCS7), 86 Mbps PHY throughput OFDMA (Downlink and Uplink) BSS […]

TinyMaix is a lightweight machine learning library for microcontrollers

Sipeed TinyMaix open-source machine learning library is designed for microcontrollers, and lightweight enough to run on a Microchip ATmega328 MCU found in the Arduino UNO board and its many clones. Developed during a weekend hackathon, the core code of TinyMax is about 400 lines long, with a binary size of about 3KB, and low RAM usage, enabling it to run the MNIST handwritten digit classification on an ATmega320 MCU with just 2KB SRAM and 32KB flash. TinyMax highlights Small footprint Core code is less than 400 lines (tm_layers.c+tm_model.c+arch_O0.h), code .text section less than 3KB Low RAM consumption, with the MNIST classification running on less than 1KB RAM Support INT8/FP32 model, convert from keras h5 or tflite.

NVIDIA Jetpack 5.0.2 release supports Ubuntu 20.04, Jetson AGX Orin

The NVIDIA Jetpack 5.0.2 production release is out with Ubuntu 20.04, the Jetson Linux 35.1 BSP 1 with Linux Kernel 5.10, an UEFI-based bootloader, support for Jetson AGX Orin module and developer kit, as new as updated packages such as CUDA 11.4, TensorRT 8.4.1, cuDNN 8.4.1. NVIDIA Jetson modules and developer kits are nice little pieces of hardware for AI workloads, but the associated NVIDIA Jetpack SDK was based on the older Ubuntu 18.04 which was not suitable for some projects. But the good news is that Ubuntu 20.04 was being worked on and initially available through the Jetpack 5.0.0/5.0.1 developer previews, and NVIDIA Jetpack 5.0.2 SDK is the first production release with support for Ubuntu 20.04. Besides the upgrade to Ubuntu 20.04, the Jetpack 5.0.2 SDK also adds support for both the Jetson AGX Orin Developer Kit and the newly-available Jetson AGX Orin 32 GB production module. It still […]
