$6 RAK3172 WisDuo LoRaWAN module features STMicro STM32WL LoRa SoC

RAK3172 WisDuo is a LoRaWAN module smaller than most coins with 15.5×15 mm dimensions made possible thanks to STMicro STM32WL Cortex-M4 LoRa SoC, which we previously found in Seeed Studio’s $10 LoRa-E5 module and corresponding development boards. But while Seeed Studio relies on STM32WLE5JC SoC with 256KB flash and 64KB RAM in a 73-pin UFBGA package, RAKwireless RAK3172 Wisduo is powered by STM32WLE5CC with the same amount of memory or storage, but in a 48-pin UFQFPN package, and an even lower price at just $5.99 in single units. RAK3172 Wisduo specifications: SoC – STMicro STM32WLE5CC55 Arm Cortex‐M4 MCU @ 48 MHz with 256 KB flash memory with ECC, 64 KB RAM, and a sub-GHz radio based on Semtech SX126x LoRaWAN 1.0.3 specification compliant Supported bands – EU433, CN470, IN865, EU868, AU915, US915, KR920, RU864, and AS923 LoRaWAN Activation by OTAA/ABP LoRa Point to Point (P2P) communication Range – Greater than […]

M5Stack Atom DTU LoRaWAN Kit also supports WiFi, RS485, Modbus communication

ESP32 WiFI, Bluetooth, LoRaWAN, and RS485 kit

M5Stack is known for its ESP32 based building blocks for the IoT with WiFi & Bluetooth wireless connectivity, I/O headers, and block-specific features like a tiny color display, a speaker, a touchscreen display, a camera, and more. The company’s latest product is the M5Stack Atom DTU LoRaWAN Kit based on ESP32 ATOM Lite, as well as ASR Micro ASR6501 LoRa module (SX1302 based) and one RS485 header that allows for industrial communication notably with the Modbus protocol.

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 […]

Cellular system-on-module integrates Quectel BG95-M3 Cat M1, NB-IoT, GPS module

Most systems-on-module come with a processor, memory, storage, and maybe a PMIC and some extra chips such as an Ethernet PHY. Some add wireless connectivity with a WiFi & Bluetooth module, but TT Electronics S-2Connect Creo SoM is more unusual as a Linux-powered SO-DIMM module with built-in Cat M1 & NB-IoT cellular connectivity, as well as GPS. This is implemented through Quectel BG95-M3 multi-mode LPWA module and an eSIM and a micro SIM socket in combination with an NXP i.MX 6UL processor Cortex-A7 processor along with 256MB RAM and a 4GB eMMC flash. S-2Connect Creo SoM specifications: SoC – NXP i.MX6UL Cortex-A7 System Memory – 256MB DDR3L Storaage – 4GB eMMC flash Connectivity LTE Cat M1 (eMTC), Cat NB2 (NB-IoT) 2G/EGPRS fallback via Quectel BG95-M3 module based on Cortex-A7 processor running ThreadX Bands LTE – 1, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26, 27, 28, […]

BastWAN Feather-compatible LoRaWAN board features RAK4260 Microchip R34 module

We’ve previously written about a Feather-compatible LoRaWAN board equipped with RAK4260 module based on Microchip R34 LoRa SIP called Penguino Feather. It appears somebody, namely Electronic Cats based in Mexico, decided to design an almost identical board with BastWAN. Let’s see if there are any differences besides the cheaper price. BastWAN specifications: LoRa module – Rak wireless RAK4260 module with: SiP – Microchip SAML21 Arm Cortex M0+ MCU @ 48 MHz, 32 KB RAM, 256 KB Flash, Semtech SX1276 LoRa Connectivity Frequency Range – 862 to 1020 MHz High level of accuracy and stability (32MHz TXCO) Max Tx Power: 20dBm; Max Sensitivity: -148dBm; Rx Current: 17mA (typical) Compliant with LoRaWan 1.0.2 Antenna – SMA and u.FL (IPEX) antenna connector I/Os – Feather headers with 20x IO pins including PWN, serial, I2C, SPI, 6x 12-bit ADC, 1x 10-bit DAC HW security – ATECC608A crypto authentication chip Programming and debugging 10-pin 4-pin […]

n-Fuse introduces SX1303 mPCIe LoRaWAN concentrator card

I first noticed Semtech SX1303 LoRa baseband processor for gateways was in RAKwireless WisGate Developer Base equipped with RAK5146 SX1303 mPCIe LoRaWAN concentrator card. But n-Fuse now offers another option with their LRWCC3-MPCIE mini PCIe card that is an update to their earlier SX1302 based n-Fuse LRWCC2-MPCIE card announced last year. n-Fuse LRWCC3-MPCIE specifications are very similar with the differences highlighted in bold: MCU – STMicro STM32 LoRa Connectivity Semtech SX1303 digital baseband processor with 2xSX1250 and 1xSX1261 Tx/Rx front-ends Frequency Range – 863 to 870 MHz or 915 to 928 MHz Sensitivity 868 Mhz <= -125dBm at SF7, BW 125KHz <= -140dBm at SF12, BW 125kHz 915 Mhz <= -125dBm at SF7, BW 125KHz <= -140dBm at SF12, BW 125kHz Max RF Output Power – Up to +27dBm Listen Before Talk prevents collisions while accessing the spectrum.
