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 […]

$70 Raspberry Pi AI Kit combines official M.2 HAT+ with Hailo-8L AI accelerator

Raspberry Pi AI Kit Raspberry Pi 5

Raspberry Pi Limited has just launched the “Raspberry Pi AI Kit”  comprised of the official M.2 Key M HAT+ and a 13 TOPS Hailo-8L M.2 AI accelerator module and selling for $70 through distributors. We had seen Raspberry Pi showcase an AI camera at Embedded World 2024, so when I received an email from a representative about a “Raspberry Pi AI Kit” I thought it would be the announcement about the camera. Instead, it’s a kit comprised of existing parts with the most interesting aspects being the price and availability (hopefully) since Hailo-8/8L accelerators are mostly found in more expensive embedded/industrial solutions, and easier documentation to get started. Raspberry Pi AI Kit highlights: Support SBC – Raspberry Pi 5 M.2 HAT+ with PCIe Gen2 x1 interfaces, M.2 Key M support, Hailo-8L AI accelerator with Up to 13 TOPS of performance M.2 2242 form factor Typical power consumption – 1.5W Thermal […]

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 […]

Mekotronics R57 – A Rockchip RK3576 Edge AI fanless mini PC with HDMI input/output, dual GbE, RS232, RS485, DIO…

Mekotronics R57 fanless RK3567 mini PC

Mekotronics R57 is a fanless edge AI mini PC powered by a Rockchip RK3576 octa-core Cortex-A72/A53 SoC with a 6 TOPS NPU, 4GB LPDDR5, a 32GB eMMC flash, and features such as RS485 and dual gigabit Ethernet that makes it suitable for industrial automation. I initially thought it was a cost-down version of the Mekotronics R58 mini PC that I reviewed with Android 12 as my first ever Rockchip RK3588 device. But while the mechanical design is similar and some of the ports are in the same position, there are some changes with the new model equipped with only one HDMI output, one HDMI input, two GbE jacks, and a terminal block with RS232, RS485, and digital inputs and outputs. Mekotronics R57 specifications: SoC – Rockchip RK3576 CPU 4x Cortex-A72 cores @ 2.2GHz, four Cortex-A53 cores @ 1.8GHz Arm Cortex-M0 MCU at 400MHz GPU – ARM Mali-G52 MC3 GPU with […]

DSTIKE Deauther Watch X is a cheap wireless hacking tool that runs the ESP8266 Deauther firmware

Deauther Watch X worn on wrist

The DSTIKE Deauther Watch X is a Wi-Fi hacking tool that can be used to test wireless networks, powered by the ESP8266 wireless microcontroller and running the open-source Deauther firmware from SpacehuhnTech. It only works on 2.4GHz networks, since 5GHz Wi-Fi is not supported by the ESP8266. It also features a real-time clock module for displaying the time, like an actual watch. If you are not familiar with the term, a Wi–Fi Deauther is a device that can perform deauth or de-authentication attacks on Wi-Fi networks. It can kick other devices off a Wi-Fi network they are connected to, for learning or other purposes. The Deauther Watch X is the latest product in the DSTIKE Deauther Watch series from Travis Lin and we previously took a look at DSTIKE ESP32 Watch Development Board. The Watch X development board comes in a wristwatch form factor, uses an ESP8266 module instead of […]
