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, […]
