Giveaway Week 2022 winners announced!

CNX Software Giveaway Week 2022 Winners

CNX Software’s Giveaway Week 2022 has just ended, and it’s time to announce the winners. Just like last year, some companies added to the review samples I offered with Rakwireless and ELECFREAKS offering a LoRaWAN devkit and an educational robot respectively. If you check out the photo of the items given away below you’ll find quite more than seven because the SONOFF NSPanel kit includes four Zigbee modules, and more importantly, we also organized a parallel giveaway week on CNX Software Thailand with small boards such as the Raspberry Pi Zero W or XIAO BLE. We had eight winners on CNX Software: NanoPi R5S gateway – Ingmar, GERMANY e-con Systems e-CAM20_CURB camera – Johnny, ESTONIA Pico:ed Smart Cutebot Kit –  jednorozec, CZECH REPUBLIC Pico:ed V2 board – Leonardo, BRAZIL Sonoff NSPanel Pro and Zigbee modules – Tim, CANADA RAK Developer Kit (Air Quality Kit) – Magnus, SWEDEN GL.iNet GL-S10 BLE […]

$858 Linux mini PC features NVIDIA Jetson Xavier NX 8GB module, 128GB NVMe SSD

NVIDIA Jetson Xavier NX mini PC

Seeed Studio is now selling the “A203 Mini PC” industrial Linux mini PC based on an NVIDIA Jetson Xavier NX module with 8GB RAM, and a 128GB SSD loaded with JetPack 5.0.2 (Ubuntu 20.04). If the name is familiar it’s because it is based on the Leetop A203 carrier board introduced about a year ago, with HDMI, two USB 3.0 ports, RS232, and other I/Os. The mini PC also offers Gigabit Ethernet, WiFi, and Bluetooth connectivity, and is designed to operate in the -20°C to 80°C temperature range for embedded, industrial, and functional safety applications. A203 mini PC specifications: System-on-Module – NVIDIA Jetson Xavier NX with hexa-core Armv8 processor, 384-core Volta GPU, 8K/4K video decoder and  4K video encoder, up to 21 TOPS of AI performance, and 8GB LPDDR4x Storage – 128GB M.2 NVMe SSD, MicroSD slot Display – HDMI 2.0 Type-A port up to 4Kp60 Camera – 1x MIPI […]

Using SenseCraft firmware for no-code programming on Wio Terminal

No code programming SHT40 sensor

In the conclusion of our SenseCAP K1100 Sensor Prototype kit review with LoRaWAN and Vision AI, the author suggested that it would be great if SeeedStudio could develop a new firmware that can connect without coding instead of using Arduino programming: I had to rely on my knowledge and experience with LoRaWAN to transmit data wirelessly over long distances. That’s because LoRaWAN has a more complicated connection process than Wi-Fi or Bluetooth. It would be great if Seeed Studio could develop a new firmware that can connect without any coding It did not take long, as SeeedStudio very recently released the first version of SenseCraft open source smart sensor software for no-code sense, process, and uplink that happens to be compatible with the Wio Terminal part of the SenseCAP K1100 development kit. So let’s test the new SenseCraft firmware together. SenseCraft navigation keys We can use Wio Terminal’s joystick as follows: […]

AI, computer vision meet LoRaWAN with SenseCAP K1100 sensor prototype kit

Wio Terminal Grove Vision AI LoRaWAN module

CNXSoft: This is another tutorial using SenseCAP K1100 sensor prototype kit translated from CNX Software Thai. This post shows how computer vision/AI vision can be combined with LoRaWAN using the Arduino-programmable Wio Terminal, a Grove camera module, and LoRa-E5 module connecting to a private LoRaWAN network using open-source tools such as Node-RED and InfluxDB. In the first part of SenseCAP K1100 review/tutorial we connected various sensors to the Wio Terminal board and transmitted the data wirelessly through the LoRa-E5 LoRaWAN module after setting the frequency band for Thailand (AS923). In the second part, we’ll connect the Grove Vision AI module part of the SenseCAP K1100 sensor prototype kit to the Wio Terminal in order to train models to capture faces and display the results from the camera on the computer. and evaluate the results of how accurate the Face detection Model is. Finally, we’ll send the data (e.g. confidence) using […]

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

SenseCAP K1100 review LoRaWAN sensors

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 […]

$4.9 CAN bus module features GD32E103 Cortex-M4 microcontroller

CAN Bus Grove module GD32E103

Seeed Studio has introduced a new CAN Bus Grove module based on 120 MHz Gigadevice GD32E103 Arm Cortex-M4+ microcontroller with support for CAN FD at up to 5Mbps and controlled by AT command over a serial interface. The new module appears to be a drop-in replacement for the company’s $19.90 Serial CAN-BUS Grove module based on Microchip MCP2551 and MCP2515, and the main benefit of the new GD32E103 module is that it is much more cost-effective going for only $4.90 including shipping. GD32E103 CAN BUS Grove module specifications: MCU – Gigadevice GD32E103 Arm Cortex-M4F microcontroller @ up to 120 MHz with 64KB to 128KB flash, 20KB to 32KB SRAM CAN Bus – 2-pin terminal block with CAN FD up to 5 Mbps Host connection – 4-pin Grove connector with UART up to 115,200 bps (default 9,600 bps) Misc – Tx and Rx LEDs Operating voltage – 3.3V Dimensions – 40 […]

reComputer J101/J202 carrier boards are designed for Jetson Nano/NX/TX2 NX SoM

recomputer J101 J201

Seeed Studio’s reComputer J101 & J202 are carrier boards with a similar form factor as the ones found in NVIDIA Jetson Nano and Jetson Xavier NX developer kits, but with a slightly different feature set. The reComputer J101 notably features different USB Type-A/Type-C ports, a microSD card, takes power from a USB Type-C port, and drops the DisplayPort connector, while the reComputer J201 board replaces the micro USB device port with a USB Type-C port, adds a CAN Bus interface, and switches to 12V power input instead of 19V. The table below summarizes the features and differences between the Jetson Nano devkit (B1), reComputer J101, Jetson Xavier NX devkit, and reComputer J202. Note the official Jetson board should also support production SoM with eMMC flash, but they do ship with a non-production SoM with a built-in MicroSD card socket instead. The carrier boards are so similar that if NVIDIA would […]

Seeed Studio outs $5 XIAO ESP32C3 board with WiFi and BLE, battery support

XIAO-ESP32C3

Seeed Studio’s XIAO family of tiny MCU boards expands with the XIAO ESP32C3 board equipped with ESP32-C3 WiFi and Bluetooth LE (BLE) microcontroller, support for LiPo batteries, and following the same 21 x 17.5mm form factor. If I’m counting right, this is the fifth member following the original XIAO based on Microchip SAMD21G18 Cortex-M0+ MCU, XIAO RP2040, and the nRF52840-based XIAO BLE and XIAO BLE Sense boards which I tested with Edge Impulse. XIAO ESP32C3 specifications: Wireless MCU –  Espressif Systems ESP32-C3 single-core RISC-V microcontroller @ 160 MHz with 400KB SRAM, 384KB ROM, 4MB flash Wi-Fi 4 & Bluetooth LE 5.0 connectivity Antenna – External u.FL antenna USB – USB Type-C port for power and programming Expansion I/Os 2x 7-pin headers with 1x UART, 1x I2C, 1x SPI, 11x GPIO (PWM), 4x ADC, I2S 3.3V I/O voltage (not 5V tolerant) Debugging – JTAG pads Misc – Reset button, Boot button, […]
