FlexiPi is a bendable Raspberry Pi Pico clone made of flexible PCB (Crowdfunding)

FlexiPi is a bendable Raspberry Pi RP2040 board made of flexible PCB with the same layout as the original Raspberry Pi Pico, but featuring a USB-C port instead of a micro USB port on the official board. This follows the Flexduino flex PCB clone of the Arduino UNO made by “EDISON SCIENCE CORNER”, but the smaller design of “TOP Gadgets” FlexiPi may make it potentially more useful since it could be inserted into tight or round enclosures. FlexiPi specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 48 MHz (overclockable to 133 MHz) with 264KB SRAM Storage – 2MB QSPI flash USB – 1x USB Type-C 1.1 port used for power and programming Expansion 2x 20-pin 2.54mm pitch header and castellated holes with 26 GPIOs, 3x 12-bit ADC up to 500 Kbps, 2x UART, 2x I2C, 2x SPI, 16x PWM, 2x programmable high-speed I/O 3.3V I/O voltage Sensor – […]

SONOFF ZBMINIR2 review – A mini Zigbee switch & Zigbee router tested with eWeLink and Home Assistant

We have received another Zigbee device from SONOFF for review, namely the ZBMINIR2 which we’ll review with both eWelink adn Home Assistant. Many people may be familiar with the first-generation mini Zigbee Switch that SONOFF released in 2020, known as the ZBMINI. ZBMINI was one of the early Zigbee Switch models, which also acted as a Zigbee Router. The ZBMINIR2 is SONOFF’s second-generation mini Zigbee Switch including both software and hardware upgrades compared to its predecessor. Improvements include a smaller size, better signal quality, an increase in the number of supported devices (2x), wider coverage (5x), and additional features. Let’s dive into the details. Unboxing ZBMINIR2 Zigbee switch Inside the box, you’ll find a small user manual and the ZBMINIR2 device as usual. It is notably smaller than the predecessor model, which makes installation much easier in many cases. For example, it can now fit into the wall box behind […]

Renesas RX260 and RX261 64 MHz RXv3 MCUs target power-efficient touch applications

Renesas RX260 RX261 RXv3 microcontrollers

The Renesas RX260 and RX261 two new 64 MHz microcontrollers part of the high-performance, high-efficiency RX product family with integrated capacitive touch-sensing and high power efficiency in both active and standby modes. The microcontrollers are based on the RXv3 core with a performance score of 355 CoreMark @ 64MHz, which is “2.5 times higher than competing 64 MHz class MCUs.” The chips are also power-efficient, with a consumption rate of 69μA/MHz during active operation and 1μA only in standby mode. According to Renesas, the chips are up to 25% more efficient in active mode and 87% more efficient in standby mode than other 64 MHz class MCUs. Another competing factor is the onboard 8KB of data flash, eliminating the need for external EEPROM. The RX260 and RX261 Group MCUs support noise- and water-resistant capacitive touch via Renesas’ third-generation capacitive touch IP (CTSU2SL). They also integrate an “automatic judgment function” that […]
