NiCE5340 SoM packs Nordic nRF5340 MCU, Lattice iCE40 FPGA, and 11 sensors into a tiny 29x16mm form factor

Stefano Viola's NiCE5340 SoM

Stefano Viola’s NiCE5340 SoM is built around a Nordic Semi nRF5340 Bluetooth SoC, an iCE40 FPGA, 11 sensors, a battery charger, and various other peripherals in a 29×16 mm form factor. The nRF5340 used in the SoM is a low-power, dual-core Arm Cortex-M33 SoC with Bluetooth 5.4, Bluetooth LE (BLE), Thread, Zigbee, and other proprietary protocols. Meanwhile, the Lattice iCE40 FPGA features 3520 logic cells, 80 Kbits of embedded Block RAM, I2C, and SPI blocks, and many other features that make it suitable for applications like environmental monitoring, health tracking, and others. Previously, we have written about Unexpected Maker NANOS3, TinyS3, FeatherS3, and ProS3 boards, and ESP32-S3 4G dev board which all fall under the tiny and compact board category but this is the first time we have seen an MCU board with so many features built into a module of that size.

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

GDM7243SL2 block diagram

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 […]

FOSDEM 2024 schedule – Open-source embedded, mobile, IoT, robotics, RISC-V, etc..


FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where thousands of developers meet in Brussels on the first week-end of February to discuss open-source software & hardware projects. FOSDEM 2024 will take place on February 3-4 with 880 speakers, 818 events, and 66 tracks. Although I won’t attend, I’ve created a virtual schedule like every year with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “FOSS Mobile Devices”, “ Energy: Reimagining this Ecosystem through Open Source”, “RISC-V”, and others. FOSDEM Day 1 – Saturday, February 3, 2024 10:30 – 10:55 – Screen Sharing on Raspberry Pi 5 Using VNC in Weston and Wayland with the Yocto Project and OpenEmbedded by Leon Anavi In 2023, embedded Linux developers received eagerly awaited news: […]

MicroPython 1.20 released with Raspberry Pi Pico W support, mip package manager, smaller footprint

MicroPython 1.20 Pico W

Damien George has recently announced the release of MicroPython 1.20 with support for the Raspberry Pi Pico W board., a new lightweight package manager called mip, a smaller footprint thanks to the use of compressed type structs, and many other changes. mip package manager The new mip package manager uses a custom protocol optimized for embedded systems to query and install packages, and intends to replace upip for installing packages from micropython-lib or any URL. Mip can be run directly on a device, as long as it has network connectivity, or via mpremote from a host computer. Damien explains all pure-Python drivers have been moved from the micropython repository to the micropython-lib repository as part of the change in order to make it easier to install the packages needed for a given project. MicroPython is getting smaller The MicroPython binary size has been reduced by many kilobytes for all ports […]

HARDWARIO CHESTER – A configurable Zephyr OS LPWAN IoT gateway with LoRaWAN, LTE IoT, GNSS connectivity

CHESTER configurable IoT gateway

HARDWARIO CHESTER platform is a configurable LPWAN IoT gateway whose main function is to connect as many devices and environments as possible to the Internet using connectivity such as LoRaWAN, LTE Cat M1, or NB-IoT, as well as GNSS for geolocation. Contrary to most IoT gateways, it does not run Linux on an application processor, and instead, the “brain” of the CHESTER IoT gateway is a Raytac Bluetooth 5.0 module based on a Nordic Semi nRF52840 Arm Cortex-M4 microcontroller running Zephyr real-time operating system, which connects to LTE IoT modem and a LoRaWAN module through UART, and expansion modules through I2C, 1-wire, and GPIO interfaces.

Embedded Open Source Summit 2023 schedule – Zephyr OS, Security, IoT, Embedded Linux, and more

Embedded Open Source Summit 2023

The Linux Foundation has just announced the full schedule for the Embedded Open Source Summit, which will take place on June 27-30, 2023 in Prague, Czech Republic, as well as virtually starting on June 26. Over 175 sessions, birds of a feather (BoF) tracks, and workshops related to embedded and open-source innovation will be presented at the event itself comprised of six micro conferences: Automotive Linux Summit Europe, Embedded IoT Summit, Embedded Linux Conference, LF Energy Embedded Summit, Safety-Critical Software Summit, and Zephyr Project Developer Summit. Even though I’m not going to attend personally, I’ve gone through the schedule to create my own little virtual schedule with some sessions relevant that should be interesting to me and hopefully to CNX Software readers. Monday, June 26 (Virtual sessions) The first day of the event will have a Yocto Dev training in the morning, and a bunch of virtual sessions that are […]
