UG65 LoRaWAN gateway supports Node-RED, up to 2,000 nodes

Node-RED is a popular flow-based, visual programming development tool originally developed by IBM for wiring together hardware devices, APIs, and online services as part of the Internet of Things. But despite being designed for the IoT, I’ve seldom seen Node-RED support for LoRaWAN hardware, the only exception being the Axon platform, a tiny WiFi & LoRaWAN board. But there’s at least one more option with Milestone IoT’s UG65 LoRaWAN gateway, launched late last year, getting a firmware update that adds Node-RED support. UG65 LoRaWAN gateway specifications: SoC – NXP quad-core Cortex-A53 processor @ 1.5 GHz System Memory – 512 MB DDR4 RAM Storage – 8 GB eMMC flash Connectivity LoRaWAN Semtech SX1302 based Fully Integrated Internal Antenna (Optional: 1 × 50 Ω N-Female External Antenna Connector) 8 channels Frequency Bands – CN470, IN865, EU868, RU864, US915, AU915, KR920, AS923 Sensitivity – -140dBm Sensitivity @292bps Output Power – 27dBm Max Protocol […]

PGA2040 is a Compact Raspberry Pi RP2040 Breakout Board by Pimoroni

Pimoroni is known for its development boards with a small form factor. PGA2040 is another compact breakout board featuring the Raspberry Pi RP2040 microcontroller. The board comes in the form of a Pin Grid Array (PGA) with RP2040 at its center. The PGA allows the accommodation of 48 pins around the perimeter of SoC on such a small footprint. After seeing some of the advanced RP2040 boards featuring wireless functionalities in the past few months, such as the Arduino Nano RP2040 Connect board, Pico Wireless Carrier board, and Wio RP2040 Mini development board, the PGA2040 is a simple board with only necessary components, thus making it suitable for compact, simple applications. However, this increases the complexity and efforts from users for interfacing additional components to implement advanced applications. Talking more about the necessary components on the board, it comes with a Crystal Oscillator, 8MB of QSPI flash, and a 3V3 […]

PC-based Logic Analyzers Comparison: PGY-LA-EMBD vs Logic16 Pro vs SP209

Comparison of PGY-LA-EMBD vs Logic16 Pro vs SP209

Building an embedded system requires multiple devices to communicate with the central processor, generally through an SPI or I2C bus. If your system is quite complex and things don’t work out as expected, then a Logic Analyzer might save your day. So, choosing the correct Logic Analyzer is critical to a successful project. This article gives a PC-based Logic Analyzers comparison, and we’ll compare products from three companies: Prodigy Technovations, Saleae, and Ikalogic. Factors to keep in mind while selecting a Logic Analyzer Before we dive into the comparison part, we should be aware of a few points based on which we’ll compare them. Logic analyzers come with a certain number of channels. The higher the number of channels is, the costlier is the product. So, select the number of channels appropriately depending on the size of your project. Several other technical specifications should also be considered, which are listed […]

Posture correction smart sensor helps you sit or stand upright

It’s easy to adopt a bad posture either while sitting in front of a computer or while walking and your mobile, and over time this may lead to unaesthetic and/or painful postural disorders. To solve this issue, a posture correction smart sensor may be used in place of a posture belt with what looks like a GPS tracker placed on the back of the patient, and which notifies bad postures by vibrating and to your smartphone depending on a user-configured angle range. Specifications listed for the posture-correction-smart-sensor: Sensor – Unnamed Bosch gravity sensor Connectivity – Bluetooth 4.2 Misc Medical-grade gel patch to attach the device to the bag Vibration motor Battery – 200mAh; 30 minutes charge good for about 5 days when using it for about 8 hours per day Dimensions – 6 x 4 x 1.2 cm Weight – 16 grams. The device ships with a micro USB cable […]

$3.5 RV-Debugger Plus UART & JTAG debug board comes with BL702 Zigbee & BLE RISC-V SoC

USB to UART debug boards are a necessity for anyone playing with single board computers, at least when using bleeding-edge bootloader or Linux kernel where the target board may not always boot, or when troubleshooting booting problems. Those are often based on FDTI or WCH chips, but Sipeed RV-Debugger Plus features Bouffalo Lab BL702 Zigbee & Bluetooth LE RISC-V SoC instead and offers both UART and JTAG interfaces. So let’s have a look at both the board and SoC. Sipeed RV-Debugger Plus USB to TLL debug boards are meant to be simple and that’s the case for Sipeed latest BL702 board as it comes with a 12-pin connector with Tx/Rx for UART, 8 signals for JTAG, plus 5V, 3.3V, and GND power signals. We can also see pads for Tx/Rx/CTS, a boot button, a crystal oscillator, and a USB-C port to connect to the host computer. What I don’t see […]
