Semtech SX1302 LoRa Transceiver to Deliver Cheaper, More Efficient Gateways

SX1302 Raspberry Pi Gateway

After our interview with Rak Wireless CEO, we received a comment inquiring about the availability of SX1302 gateways. Semtech so far had two LoRa transceivers for gateways namely SX1301 and SX1308, but I had never heard about a third one. Semtech SX1302 is brand new, the latest generation of baseband LoRa chip for gateways that is said to reduce current consumption in order to simplify the thermal design of gateways, as well as the BoM (bill of materials) costs), while being capable of handling a higher amount of traffic. Semtech SX1302 LoRa Transceiver Key features: Up to -141 dBm sensitivity with SX1250 Tx/Rx front-end 125 kHz LoRa reception with: 8 x 8 channels LoRa packet detectors 8 x SF5-SF12 LoRa demodulators 8 x SF5-SF10 LoRa demodulators 125 /250 / 500 kHz LoRa demodulator (G)FSK demodulator Direct interface to Semtech transceivers SX1255, SX1257 and SX1250 SPI host interface Single 32 MHz clock QFN68 Package Temperature Range – -40°C to +85°C.

Atomic Pi x86 SBC Meets Intel Neural Compute Stick 2 in $99 Neural Computing DevKit (Crowdfunding)

Atomic Pi Neural Computing Development Kit

IoT Team launched the $34 Atomic Pi SBC powered by an Intel Atom x5-Z8350 processor via a Kickstarter campaign last December. At the time, it only ships to the US, and looked too good to be true. But the thing is real coming from a failed robotics project, and the low-cost x86 board went back for sale via Amazon and other channels with worldwide availability last spring. The price has even gone a bit lower as you’ll find it for $32.95 on Amazon. Note that it requires some technical skills to get started and with 16GB eMMC flash it only supports Liux distributions such as Ubuntu 18.04, and installing Windows 10 is possible, but you’ll be seriously limited. Atomic Pi is back in the news, as IoT Team has now launched another Kickstarter campaign for the board, except it’s not sold standalone, but instead as part of a $99 neural computing development kit that combines Atomic Pi SBC with 2GB …

Energous Launches WattUp Hearables Developer Kit with Near-Field Wireless Charging

WattUp Hearables Developer Kit

We previously wrote about Energous WattUp near, mid, and far-field wireless charging while covering SKIIN smart underwears that could be recharged using WattUp near-field wireless technology, but the technology inside can also support future on the desk (mid-field) or in the room (far-field) charging. The company has now introduced the WattUp hearables developer kit that sadly still does not seem to support mid- and far-field charging yet but provides everything to manufacturers to get started with wireless charging for Bluetooth earbuds, smart headphones, and similar gadgets. The kit offers all hardware and software resource to get started with developing wirelessly charged audio devices: Transmitter reference design with power supply, based on Dialog Semi DA14680 Bluetooth LE chip, DA4100 wireless power transmitter, as well as EN3921 and EN3913M front end ICs. Receiver reference design with DA2223 RF to DC receiver and DA14585 Bluetooth LE SoC Mobile app Reference design user guide Datasheets Transmitter schematic and layout Receiver schematic and layout Software …

ESP32-MeshKit is a Development Kit for ESP32 Mesh Networking

ESP-MESH kit

The ESP8266 was a jewel in its peak, it ruled the maker’s world in the need for creating a low-cost WiFi module. Being Arduino compatible also furthered  its glory then the ESP32 came in. ESP32 offered so much more than the ESP8266, and most importantly it was also affordable. With support for Bluetooth and WiFi, ESP32 was to open a new frontier for the development of Internet of Things applications. A major drawback of the affordable ESP32 was the lack of official support of mesh network for the chip, something that was easily possible with the ESP8266. Mesh network allows you to build a network of nodes that can communicate with each other, self heal, and many more possibilities.  But thankfully, back in 2018, Espressif Systems released the ESP Mesh Development Framework (ESP-MDF) which sits on top of the IoT Development Framework (ESP-IDF), the official development framework for the chip. The launch of the framework makes it possible to develop …

GigaDevice Releases GD32V RISC-V MCU and Development Boards

GD32VF103 RISC-V General Purpose MCU

A few years ago, we came across GigaDevice GD32 microcontroller compatible with STMicro STM32F103, but with a higher 108 MHz clock, and zero wait state internal flash. The MCU was also a drop-in replacement for the STMicro alternative since beside being software compatible, it was also pin-to-pin compatible. The company is now back with a new microcontroller, but it’s not Arm-based. Instead, GigaDevice GD32V is based on RISC-V open source architecture. GD32V General Purpose RISC-V MCU GigaDevice GD32V is a 32-bit RISC-V general-purpose MCU that targets industrial and consumer applications such as IoT, edge computing, artificial intelligence and “vertical industries”. The new GD32VF103 series RISC-V MCU family features 14 models with the following key specifications: Core – GD32VF103 32-bit rv32imac RISC-V “Bumblebee Core” @ 108 MHz Memory – 8KB to 32KB SRAM Storage  – 16KB to 128KB flash Peripherals – USB OTG and CAN 2.0B I/O – 3.3V, 5V tolerant Supply Voltage – 2.6 to 3.6V Package – QFN36, LQFP48, …
