Retrocomputing enthusiasts will be delighted to learn that a new ZX Spectrum replica is on the market: the ESP32 Rainbow. The single board computer swaps the Zilog Z80 for an ESP32-S3 microcontroller chip running an emulator, bringing the classic 80s computer back to life with a modern twist. It features a built-in color display, a microSD card slot for storage, a built-in touch keyboard in the ZX Spectrum style, and a USB Type-C port for power and data. The keyboard was recreated using full-color UV printing and is the most true-to-life component of the ESP32-S3-based ZX Spectrum single board computer. The touch keys won’t likely offer the best typing experience but that is reminiscent of the original ZX Spectrum. A lovely cherry on top is that the onboard USB-C port supports HID and the device can be used as a keyboard on another computer. The ZX Spectrum is one of […]

The CYOBot Crawler is a four-legged robot powered by eight 180-degree servo motors. The CYOBot Wheeler form factor features four 360-degree motors linked to wheels at the end of each leg and is essentially a hybrid between […]
STMicro STSPIN32G0 3-phase motor controllers support up to 24V for portable appliances, up to 600V for industrial automation
STMicro STSPIN32G0 is a new series of advanced 3-phase motor controllers with variable voltage ranging from 45V to 600V that extend STMicro’s portfolio of devices with an integrated MCU and motor driver. The new series combines a triple-half bridge gate driver with the Arm Cortex-M0+-based STM32G0 microcontroller and is capable of handling six-step and field-oriented control (FOC) algorithms. The integrated design of the STSPIN32G0 series offers cost-savings and “significant BOM area reduction without compromising performance and robustness.” There are two main versions of the STSPIN32G0 series, low-voltage and high-voltage. The low-voltage 3-phase motor controllers include a voltage regulator, one or three shunts, and a gate driver rated at 45V and up to 0.6A. They are mainly targeted at home appliances, power tools, and drones. The high-voltage versions can handle either 250V or 600V, making them suitable for industrial inverters and fans. They are targeted at home appliances, air conditioners, home […]
iBASE IB962 3.5-inch SBC features Intel Core Ultra 5/7 SoC, up to 64GB SODIMM memory, and three M.2 slots
iBASE Technology has unveiled the IB962 3.5-inch single-board computer (SBC) powered by the Intel Core Ultra 5/7 100 Series processor family (formerly Meteor Lake U/H) and delivering an “optimal balance of performance and power efficiency.” The IB962 3.5-inch SBC mostly follows the IB961 board‘s design, offering more powerful SoC options, more system memory, and an HDMI 2.0 display interface supporting 4K resolution at 60Hz. It provides dual Gigabit Ethernet networking, three USB 3.2 ports (two via pin headers), three USB 2.0 ports, and three M.2 slots (M-Key + E-Key + B-Key) for networking, storage, and cellular communication. While IB962 is not a single-board computer in the strictest sense since it uses SODIMM sockets, it is still quite compact and useful for portable or space-constrained applications. It is intended for industrial automation, manufacturing, retail, entertainment, healthcare, and various edge AI applications. It is a larger alternative to AAEON’s PICO-MTU4 Pico-ITX SBC […]
Signaloid C0-microSD is an iCE40UP5K FPGA SoM in the microSD card form factor (Crowdfunding)
Cambridge-based hardware and cloud computing company, Signaloid has begun crowdfunding for the C0-microSD – a tiny, programmable iCE40UP5K FPGA system-on-module (SoM) in a microSD card form factor. It comes preloaded with a RISC-V softcore and users can also load custom FPGA designs onto the board. Part of the Signaloid C0-microSD’s unique appeal is its SD card form factor, which allows it to fit in unused full SD or microSD slots. This allows the implementation of FPGA-based hardware acceleration in systems without traditional expansion interfaces like PCIe M.2 slots. It can also be interfaced with as a standard SD block device and used to bring hardware-accelerated data processing to existing industrial automation, manufacturing, and robotics systems. The iCE40UP5K FPGA SoM has two main use cases: a hot-pluggable FPGA module or a hot-pluggable RISC-V co-processor module. The SD interface allows you to load custom FPGA bitstreams and applications onto the module from […]
