STMicro ST4SIM-300 eSIM complies with SGP.32 GSMA eSIM Standard for IoT

STMicroelectronics has recently released the ST4SIM-300 eSIM, the first embedded SIM (eSIM) IC that complies with the new GSMA eSIM IoT Technical Specification (SGP.32). The chip is fully compliant with remote SIM provisioning of the GSMA eSIM IoT standards, so it works with 2G, 3G, 4G (LTE), CDMA, NB-IoT, and Cat-M networks. It is designed for small IoT devices and allows system operators to remotely program device subscriber identities over the air (OTA), making it a plug-and-play solution for seamless integration and management. Previously, we have written about Hologram’s IoT eSIM Chip that provides global connectivity and comes with 2FF, 3FF, 4FF, and Mff2- M2M form factors. We have also written about the Conexio Stratus Pro battery-powered nRF9161 development kit that supports eSIM as an option.

SparkFun RTK EVK offers GNSS with centimeter accuracy, WiFi, Bluetooth, 4G LTE Cat 1, and Ethernet connectivity

SparkFun RTK EVK is a fully-enclosed GNSS platform designed for fixed or mobile high-precision positioning and navigation applications with centimeter accuracy thanks to RTK (real-time kinematic) technology implemented with modules from u-blox. About two months ago, Sparkfun introduced the RTK Torch waterproof GNSS surveyor with Unicore UM980 GNSS module with RTK support, ESP32 for WiFi/Bluetooth, and an STM32WLE5C LoRa SoC. The SparkFun RTK EVK (evaluation kit) may drop LoRa connectivity, but it’s a more versatile platform with WiFi, Bluetooth, Ethernet, and LTE Cat 1 cellular connectivity, besides support for L1 + L2 RTK GNSS with L-Band correction. Sparkfun RTK EVK specifications: GNSS Receiver – u-blox ZED-F9P Concurrent reception of GPS, GLONASS, Galileo, and BeiDou Receives both L1C/A and L2C bands 184-channel u-blox F9 engine Time to First Fix: 25s (cold), 2s (hot) Max Navigation Rate: 20Hz / 25Hz depending on mode Horizontal Position Accuracy: 2.5m without RTK; 0.010m with RTK […]

HIGOLE F9B Pro Intel N100 mini computer comes with a built-in 7-inch touchscreen display and 5,000 mAh battery

HIGOLE F9B Pro mini PC with 7-inch touchscreen display

HIGOLE F9B Pro is a mini PC powered by an Intel Processor N100 quad-core CPU and equipped with a built-in 7-inch touchscreen display, a 5,000mAh battery, and full-size ports that could be confused with a 7-inch tablet if it was not so thick… GOLE/HIGOLE has made many such mini PCs with integrated displays over the years initially to lower the Windows license fee, but they’ve kept making those with new Intel families, for example with the Gemini Lake-powered GOLE1 Pro mini PC with a 5.5-inch display introduced in 2022. The HIGOLE F9B Pro is just the latest iteration with a modern Alder Lake-N CPU and a 7-inch touchscreen display.

GCT GDM7243SL is a dual-core RISC-V 5G/4G LTE modem with support for NTN, NB-IoT, LTE Cat M, Cat1bis, Cat1 and/or Cat4

CT Semiconductor Holding GDM7243SL is a multi-mode 5G/4G LTE IoT modem with two 400 MHz RISC-V cores capable of operating in Cat 4, Cat 1bis, Cat M1, Cat NB1/NB2 (NB-IoT) and non-terrestrial networks (NTN) in order to work anywhere on earth. If I remember correctly, one of the first commercial RISC-V SoCs I saw was a storage controller from Western Digital introduced in 2019. But since then, we’ve seen more and more RISC-V chips come to market from entry-level microcontrollers up to Linux-capable application processors, and even chips for datacenters that are out of the scope of topics covered on CNX Software. But with GDM7243SL, I think it’s the first time I’ve encountered a RISC-V modem, so let’s have a closer look. There are two models, the GDM7243SL1 and GDM7243SL2, with different memory and storage options, and the L1 lacks support for LTE Cat 4. GDM7243SL key features: CPU 400 […]
