Giveaway Week 2024 – Jupiter RISC-V mini-ITX motherboard

The 11th edition of CNX Software giveaway week is underway! We have seven items to give away this time around: six review samples I will send myself and one from a company offering one of its cellular IoT development kits… The contest is open worldwide, and CNX Software Thailand is also joining the fun with four additional items available to people with an address in Thailand. The first prize of this year’s giveaway is Shenzhen MILK-V Technology’s Jupiter RISC-V mini-ITX motherboard powered by a 1.8 GHz SpacemiT K1/M1 octa-core processor, equipped with 16GB LPDDR4x, and various interfaces and features such as M.2 PCIe 2.0 x2 socket for an NVMe SSD, a 4K-capable HDMI video output, two gigabit Ethernet ports, WiFi 6 and Bluetooth 5 module, and more. I reviewed the Jupiter mini-ITX motherboard with Ubuntu-based Bianbu OS and an Auriga 6-Bay NAS mini-ITX chassis last August and the results were […]

Murata unveils stretchable PCB technology for medical and bio-sensing applications

Many PCB vendors now provide flexible PCB manufacturing services, but Murata goes further with stretchable PCB technology that’s not only bendable but can be twisted and stretched to better fit on the body for bio-sensing and medical applications even on parts such as an elbow. Traditional bio-monitoring sensors have some limitations. For example, they can become unstuck when the body moves, damage the delicate skin of infants and the elderly, data may be distorted due to body movement, and Murata explains “there is a risk of a decline in insulation and the occurrence of ion migration when using a thermoplastic polyurethane elastomer (TPU), known as a stretchable base material, in a high humidity environment”. The company’s stretchable printed circuits ((SPC) are supposed to solve or at least mitigate all those issues. The technology is under development, but Murata still shared some highlights of the technology: Stretchable electrode printing in compliance […]

MicroPython v1.24 release adds support for RP2350 and ESP32-C6 microcontrollers, various RISC-V improvements

Micropython v1.24 with ESP32-C6 and RP2350 support

MicroPython has become one of the most popular ways of programming microcontrollers, and the just-released MicroPython v1.24 adds support for the widely-used Raspberry Pi RP2350 and Espresif ESP32-C6 microcontrollers and a range of other changes. Those include improved RISC-V support with native code generation, an updated Zephyr v3.7.0 RTOS with threading support, unified TinyUSB bindings across ports, a portable UART IRQ API, and enhanced mpremote recursive copy. Damien George goes into more detail about the RISC-V improvements: … include an RV32IMC native code emitter, native NLR and GC register scanning implementations for 32- and 64-bit RISC-V, support for placing RV32IMC native code in .mpy files and also freezing it, and RISC-V semihosting support. Testing for RISC-V is done with the qemu and unix ports, and the support is utilised in the esp32 and rp2 ports. The Raspberry Pi RP2350 comes with both Arm Cortex-M33 and RISC-V cores, and the good […]

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 – […]
