U-blox SARA-R410M-02B Module Supports LTE Cat M1 and Cat NB1 in a Single Package

We previously covered U-blox SARA-R4 LTE Cat M1 and SARA M2 NB-IoT (Cat NB1) modules, but in case you need support for LTE Cat M1 and Cat NB1, instead of just one or the other, in your product, U-blox launched a new SARA-R4 model with SARA-R410M-02B module supporting both standards. U-blox SARA-R410M-02B module specifications: LPWAN connectivity LTE Cat M1 Half-duplex: 375 kb/s DL and UL LTE Cat NB1 Half-duplex: 27.2 kb/s DL, 62.5 UL Shared bands – 1, 2, 3, 4, 5, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28; Cat M1-only band – 39 Coverage enhancement Mode A and Mode B (in upcoming firmware), 3GPP Rel 13 e-DRX (Extended Discontinuous Reception) supported in upcoming firmware SMS support – MT/MO PDU / Text mode; SMS over SG/NAS Voice – VoLTE (Cat M1) using AMR-WB codec (U)SIM supporting 1.8 and 3V GNSS/GPS support with CellLocate and Hybrid positioning coming […]

u-blox SARA-S200 RPMA Module Supports the Machine Network

RPMA is one of the many LPWAN IoT communication standards, but it does not get as much press coverage as SigFox or LoRa because it targets larger scale deployments, and is not really accessible to individuals. It’s still used by companies in many countries, and u-blox has just released SARA-S200 RPMA module that will also work with the Machine Network, also relying on RPMA and managed by Ingenu. u-blox SARA-S200 module specifications: Connectivity Wireless Frequency – 2.4 GHz ISM Radio Spectrum – 80 MHz Occupied Bandwidth – 1 MHz Modulation – Dynamic – Direct Sequence Spread Spectrum (D-DSSS) Multiple Access Scheme – Random Phase Multiple Access (RPMA) Transmit Power – +22 dBm Receive Sensitivity – -133 dBm Data Throughput – 100 kB per day Link budget – 176 dB (FCC/IC) Host Interface – 7-wire SPI that includes handshaking for deep sleep modes Power Supply – 3.2 V to 3.4 V […]

u-Blox Unveils SARA-R4 LTE Cat M1 and SARA-N2 NB-IoT Modules for Professional IoT Applications

While I’ve mostly read about SigFox and LoraWan solutions for long range, low power, and low bitrate communications for the Internet of Things so far, there are many active of planned LPWAN standards for IoT applications, and 3GPP Release 13 standard stipulates two LTE LPWAN standards, namely LTE Cat M1 (eMTC) and LTE Cat NB1 (NB-IoT), with the former supporting 1 Mbps downlink and uplink peak data rates, and the latter 250 Kbps downlink, and 250 Kbps (multi-tone) or 20 Kbps (single tone) uplink data rates. U-Blox has released modules for both standard with SARA-R4 LTE Cat M1 and SATA-N2 NB-IoT modules. SARA-N2 Cat NB1 cellular module specifications: LPWAN Connectivity – 3GPP Release 13 NB1; NB-IoT bands: 5, 8, 20; downlink: 227 Kbps, uplink: 21 Kbps Positioning – GNSS via Modem Interfaces – 1x UART, 1x SPI, 2x GPIO, 1x DDC(I2C) for GNSS Features – Antenna supervisor, embedded IPv4 & […]

Ublox NEO-6M $10 GPS Module with Antenna Works with Arduino, Raspberry Pi, etc..

Last week, I wrote about NavSpark Mini a $6 GPS + Beidou module, that’s also available for “free” plus $10 shipping. However, if you don’t have an antenna, you’d also need to add a $9 antenna, bringing the total price to $19 for this low cost GPS solution. But there’s actually a cheaper alternative with Ublox NEO-6M GPS module, as it sells for $10 with a GPS antenna including shipping on either Aliexpress or eBay. Ublox NEO-6M based GPS module specifications: NEO-6M-0-001 module Storage – EEPROM for configuration data External interfaces – UART; default baudrate: 9600 bps Misc – RTC battery (MS621FE) Power Supply – 3 to 5V The battery may not always be included due to transport regulations, so you may have to purchase it separately and solder it yourself. The module is not exactly new, and has been around at least since 2013, so there’s also some documentation, […]
