Tiny Raspberry Pi RP2040 module connects to USB-C + buttons board via FPC connector

Raspberry Pi RP2040 module with FPC USB-C board

Waveshare RP2040-Tiny is another tiny Raspberry Pi RP2040 module that joins others like Pimoroni Tiny 2040, DFRobot Beetle RP2020, or Solder Party RP2040 Stamp, but with a twist as the solderable module features an FPC connector in order to optionally connect a separate board with a USB-C port as well as Boot and Reset buttons. This design enables the convenience of having a USB-C port for power and programming, plus the Reset and Boot buttons during firmware development, and developers can only keep the tiny and ultrathin module when integrating it into a project or product. Alternatively, there may be designs that benefit from having the USB-C port located further away from the main module with all I/Os, and it can also facilitate troubleshooting when the product is already integrated into a product. Waveshare RP2040-Tiny specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB […]

Review of SONOFF BASICR4 Smart Switch and S-MATE2 Smart Remote Control

Sonoff SMATE-2 + BASICR4 automation demo

We’ve received two new devices from SONOFF for testing, namely the BASICR4 Smart Switch and the S-MATE2 Smart Remote Control. For those familiar with SONOFF devices, the Basic series is well-known as it was one of the initial products SONOFF introduced to the Smart Home market. It’s a Wi-Fi switch that can be used for various purposes, including controlling lights, fans, and other electrical devices. The BASICR4 model enhances capabilities while reducing costs compared to its predecessor. The S-MATE2, on the other hand, is the second version of a simple Remote Controller powered by batteries. It wirelessly connects to other SONOFF devices that support the eWeLink Remote Gateway feature, enabling full control within the same ecosystem. This expands its usability across different devices. Let’s delve into the details. SONOFF BASICR4 Introduction The Basic series has been a long-standing Wi-Fi Switch family allowing control of electrical devices through the eWeLink app […]

AirGradient ONE Kit Review – An open-source indoor air quality monitor

The product we are reviewing today is the “AirGradient ONE” air quality monitor kit which is an updated version of the earlier AirGradient air quality monitor. The device is equipped with sensors from Sensirion and Plantower, allowing it to measure many air quality parameters such as CO2, PM2.5, TVOCs, NOx, temperature, and humidity. It is an indoor air quality monitor that is both open-source software and open hardware. This means that the Arduino source code, schematic diagrams, PCB, and 3D models of the enclosure are available to developers. AirGradient ONE DIY Kit Unboxing The device was packaged within a cardboard box, with a greeting card from the manufacturer. The card features a QR code linking to a webpage with the installation guide. Since I requested the Kit version (there’s also a fully assembled model), some sensors were not pre-assembled and they were well-packaged in separate seals. The main PCB was […]

Microchip PIC18-Q24 8-bit MCU focuses on security and supports Multi-Voltage I/O (MVIO)

The newly introduced Microchip PIC18-Q24 8-bit MCU implements security measures such as the Programming and Debugging Interface Disable (PDID) feature and optional support for an immutable bootloader, as well as support for Multi-Voltage I/O (MVIO) to interface with digital inputs or outputs at different operating voltages without the needs for level shifters. While it’s fun to find a new MCU platform that you can hack via serial, JTAG, or other debug interfaces, it can be a security issue, and the Microchip PIC18-Q24 aims to make that impossible by disabling programming and debugging interfaces and the 8-bit microcontroller also offers an option to make the bootloader impossible to modify once a specific configuration bit has been set. Microchip PIC18-Q24 key features and specifications: MCU core – 8-bit C compiler optimized RISC core @ up to 64 MHz Memory – Up to 4 KB of Data SRAM Memory Storage – Up to […]
