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.

PCIe to 5G HAT+ for Raspberry Pi 5 takes SIMCom and Quectel 5G modules

Raspberry Pi 5 5G PCIe HAT+

Waveshare PCIe to 5G/4G/3G HAT+ for Raspberry Pi 5 is a PCIe Gen 2 x1 to M.2 HAT+ designed to take 5G modules from SIMCom and Quectel and a Nano SIM card. The kit ships with a 4-in-1 PCB antenna, associated cables, a heatsink, a 4cm 16-pin PCIe FPC cable, a 40-pin female header, and a fixture set for mounting. We had previously written about the SixFab 5G HAT for the Raspberry Pi 5 with a Quectel RM502Q-AE M.2 module, but this specific kit still relies on the USB 3.0 interface. The Waveshare kit is the first 5G kit using the PCIe interface from the Raspberry Pi 5 interface and it is offered with Quectel RM502Q-AE, RM530N-GL, RM520N-GL, or SIMCom SIM8262E-M2, SIM8262A-M2 M.2 3042/3052 modules.

DFM8001 indoor energy harvesting kit harnesses solar energy (and mechanical, thermal, RF energy with extra hardware)

DFM8001 Indoor Ambient Energy Harvesting Kit

DFRobot DFM8001 indoor ambient energy harvesting kit can power IoT devices by harnessing solar energy, and the company claims it can also capture mechanical, thermal, and RF energy from the local environment but there’s no way to do that with that kit without additional hardware. The DFRobot kit is comprised of an evaluation board with the company DFM8001 energy harvesting module, two pluggable supercapacitors, and a solar panel used as power input. You could also use other sources emitting at least 150 mV gathering energy from RF, thermal, or mechanical sources. The board features two outputs one low-voltage (1.2-1.8V) terminal up to 20mA, and a high-voltage (1.8V-4.1V) terminal up to 80mA, and two battery connectors plus a few jumpers for configuration. DFM8001 energy harvesting kit specifications: Operating voltage – 3.3V to 5.5V DC Cold start condition – Input > 400mV 15uW Sustaining voltage after cold start – 150mV. Input voltage […]

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 […]
