PicoQuake USB vibration sensor is based on the RP2040 MCU and the ICM-42688-P vibration sensor

The PicoQuake is a USB vibration sensor with a MEMS accelerometer covering a wide range of vibrations. It is capable of capturing vibrations in the low-frequency range (tall buildings, bridges) to the high-frequency range (motors, industrial machinery). It can operate as a standalone device and connect to a computer via a USB cable. Furthermore, it is based on the Raspberry Pi RP2040 microcontroller and uses a low-noise MEMS inertial measurement unit, the TDK InvenSense ICM-42688-P, which combines a 3-axis gyroscope and a 3-axis accelerometer. The low-noise IMU sensor used enables the PicoQuake to profile vibrations of very low magnitude. The PicoQuake sensor is a product from Slovenian maker, PLab, just like the FOCn driver module we took a look at recently. Potential use cases for the PicoQuake include optimizing brushless DC motor vibrations (important in small mobility products such as electric bikes and scooters), tracking trackpad clicks, smart home automation, […]

GEEKOM A8 Review – Part 2: An AMD Ryzen 9 8945HS mini PC tested with Windows 11 Pro

In the first part of the review, we’ve already gone through a teardown and an unboxing of the GEEKOM A8 AI mini PC powered by an AMD Ryzen 9 8945HS processor with AMD Radeon 780M Graphics, 32GB RAM (upgradeable up to 64GB) and a 2TB M.2 NVMe SSD. We’ve now had more time to play with the GEEKOM A8, so we will report our experience with the Windows 11 Pro operating system in the second part of the review testing features, running benchmarks, evaluating networking and storage performance, testing the thermal design, and taking measurements for fan noise and power consumption. Software overview and features testing The System->About window in the Settings confirms we have an A8 Mini PC powered by a 4.0 GHz (base frequency) AMD Ryzen 9 8945HS processor with Radeon 780M Graphics and 32GB of RAM running Windows 11 Pro 23H2 build 22631.3593. HWiNFO64 provides more details […]

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

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. Waveshare PCIe to 5G HAT+ specifications: M.2 Key B socket for 3042/3052 5G modules with PCIe interface 16-pin PCIe FPC connector directly connected to the […]

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 […]

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

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 […]
