Solder Party’s RP2350 Stamp is an update to the company’s tiny RP2040 Stamp module based on a Raspberry Pi RP2350A, and they also introduced the RP2350 Stamp XL module that makes use of the extra GPIO pins on the RP2350B, and a “RP2xxx Stamp Carrier XL” carrier board taking either module. RP2350 Stamp and RP2350 Stamp XL The RP2350 Stamp has exactly the same layout as the RP2040 Stamp and mostly benefits from the more powerful Cortex-M33 cores, additional memory, and security features, while the XL variant adds more GPIOs, footprint for a PSRAM chip, as well as UART and SWD connectors. Both come with a 16MB SPI flash for storage. RP2350 Stamp specifications: Microcontroller – Raspberry Pi RP2350A MCU CPU – Dual-core Arm Cortex-M33 processor @ 150MHz Memory – 520KB internal RAM 8KB OTP Storage Package – QFN-60; 7×7 mm Storage – 16MB flash I/Os – All 30x I/Os […]

Ezurio Sona NX611 – An NXP IW611-powered Wi-Fi 6 industrial IoT module
Ezurio, formerly Laird Connectivity, has announced the Sona NX611, a new Wi-Fi 6 module designed for industrial IoT applications. The module uses the NXP IW611 chipset and supports Wi-Fi 6 (802.11ax) and Bluetooth 5.4. It operates in the 2.4 GHz and 5 GHz bands, achieving data rates up to 600 Mbps, and can withstand industrial temperatures from -40°C to +85°C. The Sona NX611 comes in several form factors, including SiP (System-in-Package), M.2 1216 SMT, and M.2 2230 E-Key pluggable options. It is compatible with NXP processors and supports Ezurio’s Linux connectivity stack software and Android OS. The module is under development and is expected to be in mass production by September 2024. It will have global certifications like FCC, ISED, UKCA, CE, and Bluetooth SIG.

Quectel LG290P is the world’s first quad-band GNSS module (L1, L2, L5, and E6)
The Quectel LG290P is a quad-band, multi-constellation, high-precision, real-time kinematic (RTK) GNSS module that supports GPS, GLONASS, Galileo, BDS, QZSS, and NavIC constellations. A typical GNSS module like the SparkFun GNSS L1/L5 can receive signals from only one or two frequency bands, but the Quectel module can receive signals from four different frequency bands (L1, L2, L5, and E6) simultaneously and features built-in anti-jamming technology for improved signal reception in challenging environments. All these measures make this chip suitable for high-precision navigation applications like autonomous robots, UAVs, precision agriculture, surveying and mapping, and autonomous driving. Previously we have written about higher precision GPS modules like the SparkFun RTK EVK module, SparkFun RTK Torch module, the Cavli C17QS IoT GNSS module and much more feel free to check those out if you are interested in those topics.
