STMicro STM32WL is the World’s First LoRa SoC

There is no denying that the Internet of Things is going to disrupt a lot of markets and it’s already happening to some extent. The question being asked is: “What IoT connectivity technology will lead this disruption era?”. One major technology in this connectivity race is LoRa. LoRa’s long-range, low-power, small footprint, simplicity, and the amazing community backing it, have allowed it to find its way into various applications while gaining for the top LPWAN IoT connectivity technology. STMicroelectronics, one of the biggest semiconductor manufacturer, also believes in the potential of LoRa with the launch of STM32WL, making it the World’s first die-integrated LoRa System-on-Chip. Traditional LoRa embedded platforms usually involve the need for a separate MCU chip and different LoRa transceiver chips either coupled together in one single package or separately. This undoubtedly adds extra design complexity, size, and even cost. STMicro hopes to address this with their STM32WL SoC. This new device opens the door to original applications by …

RAK7244 LoRaWAN Developer Gateway Combines Raspberry Pi 4 with LoRa HAT, Optional 4G LTE Connectivity

Raspberry Pi 4 LoRaWAN LTE Gateway

After launching RAK831 Lite LoRaWAN gateway based on Raspberry Pi 3 board in 2018, RAK Wireless introduced Pilot Gateway Pro RAK7243 gateway with the more recent Raspberry Pi 3B+ SBC earlier this year. But with the launch of Raspberry Pi 4 last June, the Raspberry Pi 3B+ has become much harder to procure, so RAK has now launched an updated LoRa gateway featuring Raspberry Pi 4 SBC together with the company’s RAK2245 Pi Hat Edition LoRaWAN gateway concentrator module. RAK7244 LoRaWAN Developer Gateway specifications: SBC – Raspberry Pi 4 Model B with 2GB RAM Connectivity LoRa RAK2245 Pi Hat LoRaWAN gateway concentrator module with 1x SX1301 baseband processor, 2x SX125x Tx/Rx front-ends LoRaWAN v1.0.2 support Support for 8 channels and spreading factors SF7 to SF12 Bands – 433MHz, 470MHz, 865MHz, 868MHz, 915MHz, 920MHz, 923MHz Tx Power: 27 dBm Max RX Sensitivity: -139dBm Cellular – Optional 4G LTE support via RAK2013 Cellular Pi HAT (Quectel EG95  LTE CAT4 module) GNSS – …

Pocket Popcorn Computer Handheld Linux Computer Looks Like an Improved, Faster PocketCHIP (Crowdfunding)

Pocket Popcorn Computer

PocketCHIP was a Linux handheld computer powered by Allwinner R8/GR8 Cortex-A8 based CHIP board. The battery-powered device came with a small resistive display, 512 MB RAM, 4GB NAND flash, and a keyboard allowing to run Debian with PICO8 GUI so you could play retro games, access the terminal and so on. But since Next Thing Co folded last year the products are not available anymore. Since the designs were open source, Source Parts first tried to resurrect the board via their slightly modified Popcorn Computer but the Kickstarter campaign was unsuccessful. The company is now attempting to bring back PocketCHIP (sort of) with Pocket Popcorn Computer (abbreviated as Pocket P.C.) with a new design, and a much more powerful quad-core Cortex-A53 processor and overall better specs. Pocket Popcorn Computer specifications: SoC – Allwinner A64 quad-core Arm Cortex-A53 CPU with Arm Mali-400MP2 GPU System Memory – 2GB DDR3 RAM Storage – 32GB eMMC Memory, Internal microSD card connector Display – 4.95″ …

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.
