Spark Analyzer is an ESP32-C3-powered device built to streamline the process of developing and debugging USB-C Power Delivery (UCPD) solutions. The board’s design is simple, compact, and includes helpful power delivery and analysis functionality, at an affordable price. Spark Analyzer runs on an ESP32-C3FH4 microcontroller, a low-power SoC with a single-core RISC-V CPU with onboard 2.4 GHz Wi-Fi and Bluetooth 5 (Low Energy) connectivity. The wireless chip lets users control the Spark Analyzer and monitor its operation remotely. It also supports integration with other smart devices via Matter.  The device allows you to adjust voltage output from 5V to 20V, depending on your project requirements. Power is sent to a connected device via the two-pin screw terminal block on the device, and a Cross Chip sensor measures the electrical current sent through the device using Hall effect. It includes a software safety feature that turns off the output field-effect […]

STMicro ST60A3H0 and ST60A3H1 60 GHz transceiver ICs aim to replace USB cables

ST60A3H0 ST60A3H1 60 GHz transceivers

STMicro ST60A3H0 and ST60A3H1 are short-range 60 GHz transceiver ICs that tunnel eUSB2, I2C, SPI, UART, and GPIO signals and aim to replace USB and other cables in consumer devices such as digital cameras, wearables, portable hard drives, and small gaming terminals. They should also find their way into industrial applications such as rotating machinery where cable use may be challenging. The smaller ST60A3H0 chip provides more flexibility and requires an external antenna, while the ST60A3H1 chip is a fully integrated solution with a built-in linear antenna. Both are capable of USB 2.0 speeds of up to 480 Mbps and support UART, GPIO, and/or I2C signals so they are not limited to USB cables and can be used in a range of applications. ST60A3H0 and ST60A3H1 key features and specifications: 60 GHz V-Band transceiver for short-range contactless connectivity up to 480 Mbit/s eUSB2, UART, GPIO, or I2C RF tunneling Low […]

Ovrdrive USB is an open-source, privacy-oriented USB flash drive that can self-destruct (Crowdfunding)

Ovrdrive USB flash

We have previously covered the Tillitis Tkey, an open-source security key in a USB-C case but the Ovrdrive USB stick is not a security key. It is a simple, plain USB flash drive with a special security feature. It will appear completely blank unless you plug this drive in three times in quick succession. The Ovrdrive flash drive is aimed at journalists in repressive areas and security researchers but may be useful to other security and open-source hardware enthusiasts. As for how it works, the Ovrdrive has two identical circuits connected to the ATtiny24A microcontroller that controls the rapid plug-in functionality. When the flash is plugged in, the microcontroller powers on, and the CHG1 node goes high, charging C3 through D2. The pin will remain high for a while and then slowly discharge via R1 and body resistance. C3 and the identical C14 will remain high through power cycling/a quick […]

Solar power manager module supports 6V-24V input range, battery charging, MPTT function, and outputs 5V/3A

Raspberry Pi 4 solar panel

Waveshare Solar Power Manager Module (D) is a compact power module for solar panels with support for 6V to 24V input, MPTT (Maximum Power Point Tracking), and battery charging. It outputs 5V up to 3A via a USB-C port or terminal block and should be suitable for a range of projects. A few weeks ago, we wrote about the FireBeetle 2 ESP32-C6 IoT development board with DFRobot highlighting support for solar charging of lithium batteries thanks the the CN3165 chip. But with a range of just 4.5 to 6V for solar panel input and a lack of support for MPTT, several readers were unimpressed by the solution. The Waveshare Solar Power Manager Module (D) recently popped up in my news feed, and I thought it might be worth a look. Waveshare Solar Power Manager Module (D) specifications: Solar panel input 6V to 24V via DC jack or 2-pole screw terminal […]

Mcuzone MP4GM 4G LTE PCIe Module for Raspberry Pi 5 also adds three USB 2.0 interfaces

Pi5 PCIE 4G LTE Module with USB

Mcuzone recently announced the MP4GM, a new 4G LTE module for the Raspberry Pi 5 SBC. This module connects to the Raspberry Pi 5 via PCIe and includes three extra 1.25mm JST connectors for three additional USB 2.0 interfaces. This HAT is compatible with various 4G LTE mini PCIe modules from Mcuzone and Fibocom, providing flexible options for 4G connectivity. We have previously covered a 5G Modem Kit for the Raspberry Pi 5, but this is the first time we have found out about a 4G LTE kit designed for the Pi 5. We have also covered Mcuzone RK3308 SoM and the MDK3308-EK Evaluation Kit, designed for smart voice applications as well as a Raspberry Pi CM4 board with dual Ethernet capabilities all from MCUzone. So, feel free to check those out if you are interested in their products. Mcuzone MP4GM 4G LTE module specification: Model – MP4GM PCIe to […]

Tillitis Tkey is an open-source RISC-V security key in a USB-C case

Tkey security key with an open lid

Tillitis’ TKey is a small, simple security key in a USB-C form factor, and described as a “new type of flexible USB security token” that is inspired by DICE (Device Identifier Composition Engine) and measured boot powered by a simple 32-bit RISC-V core, the PicoRV32, in a Lattice iCE40 UP5K FPGA. While we have covered hardware security modules in the past, this is the first security key we have seen that is based on an FPGA running a RISC-V core. The security token lacks persistent, onboard storage, unlike alternatives such as Yubikey Neo. Apps need to be loaded onto the key every time it is connected to a host device. It uses measured boot to generate a unique identifier for each application and is more secure than the alternatives since private keys are not stored on the device. Also, the hardware and software for the TKey are completely open-source for […]
