Microflex MCUs – Tiny USB development boards based on ESP32-S3, ESP32-S2, ESP32-C3, ESP32-C6, or Raspberry Pi RP2040 (Crowdfunding)

Microflex MCU board with ESP32 and RP2040 microcontrollers

SB Components is back with yet another crowdfunding campaign this time with the Microflex MCUs USB development boards all with the same tiny form factor and offered with a choice of five microcontrollers namely Raspberry Pi RP2040, ESP32-S3, ESP32-S2, ESP32-C3, or ESP32-C6. Microflex MCUs share the same layout with a USB-C port for power and programming, a built-in RGB LED, two buttons for Boot and Reset/User, and two rows of 10-pin with through and castellated holes to access the GPIOs and power signals such as 5V, 3.3V, and GND. But they differ in terms of the processor used, wireless features, and available I/Os as shown in the table below which sadly lacks any information about the flash and eventual PSRAM… The illustration below includes some more details for the Micro-C6 with the main components, ports, and a pinout diagram. Programming the firmware for the ESP32-series can be done through the […]

STMicro VD55G1 – A small, low-power global shutter I3C camera sensor for computer vision

STMicro VD55G1 global shutter camera sensor

STMicro VD55G1 is a new global shutter I3C camera sensor with a small die size of 2.7 x 2.2 mm, 804 x 704 pixels native resolution, and consuming about 1mW in its ‘always-on’ autonomous mode to wake up the host when motion is detected. Camera sensors are available with rolling or global shutter, with most from the former type, but as we’ve seen in our reviews of the e-Con Systems See3CAM_24CUG (USB 3.1) and the Raspberry Pi Global Shutter (MIPI CSI) global shutter cameras, the latter is much better we capturing moving objects clearly at high frame rates with fewer artifacts than with rolling cameras. The VD55G1 global shutter sensor will also benefit from the same advantage but is offered in a smaller package working over MIPI CSI and/or I3C, making it suitable for devices with small batteries used in applications such as eye tracking or motion estimation. STMicro VD55G1 […]

CWWK x86-P5 fanless mini PC with two 2.5GbE ports ships with up to Intel Core i3-N305 CPU

x86-P5 mini PC

CWWK x86-P5 is a fanless mini PC powered by an Intel Alder Lake N-series N100 (quad-core) or Core i3-N305 (octa-core) and equipped with two 2.5GbE ports using Intel i226V controllers making it suitable for networking applications such as a firewall or a soft router. But it’s also a standard mini PC with two HDMI 2.0 ports, two USB 3.2 ports, and up to four USB 2.0 ports making it a candidate to run Promox with both a desktop OS like Windows 11 or Ubuntu 22.04 and a networking OS such as pfSense or OpenWrt. CWWK x86-P5 specifications: Alder Lake-N SoC(one or the other) Intel Processor N100 quad-core processor @ up to 3.4 GHz (Turbo) with 6MB cache, 24EU Intel UHD graphics; TDP: 6W Intel Core i3-N305 octa-core processor @ up to 3.8 GHz (Turbo) with 6MB cache, 32EU Intel UHD Graphics; TDP: 15W System Memory – Up to 32GB DDR5 […]

Raspberry Pi releases PCIe FFC connector specifications, new HAT+ standard

Raspberry Pi 5 PCIe pinout and FFC cable

Raspberry Pi has released two new specifications one for the PCIe FFC connector and related cable and the other for the new Raspberry Pi HAT+ (HAT Plus) standard that’s simpler, takes into account new features in Raspberry Pi 4/5, and has fewer rules around mechanical dimensions. PCIe FFC connector specifications The Raspberry Pi 5 was announced over 2 months ago with a new PCIe FFC connector, and people may been playing around with it and even launching products such as an M.2 HAT for the Raspberry Pi 5 since then even though the pinout and specifications were not available. But Raspberry Pi has now released the specifications (PDF) for the PCIe FFC found in the Raspberry Pi 5 and likely future models as well. The 16-pin 0.5mm pitch FFC connector features a single lane PCIe interface, something we knew already, but the pinout diagram and recommendations for the FFC cable […]

UP 7000 SBC review – Part 2: Ubuntu 22.04 on a fanless Intel N100 single board computer

UP 7000 Ubuntu 22.04 review

The UP 7000 is a credit card-sized Alder Lake-N single board computer that can be used as an alternative to the Raspberry Pi 5 for industrial applications. AAEON sent me a model with an Intel Processor N100 CPU, 8GB LPDDR5, and a 64GB eMMC flash, and I went through an unboxing in the first part of the review, compared its mechanical design to the earlier UP 4000 and Raspberry Pi 5 SBC , and also installed Ubuntu 22.04 since the UP 7000 board did not come with any OS and would initially boot to the UEFI shell. I’ve now spent more time with the board and I will report my experience with the UP 7000 SBC running Ubuntu 22.04 in this article checking out features, performance, video playback, power consumption, and so on using the UP 4000 review with Ubuntu 22.04 I did last year as a template plus some […]

LONGER Laser B1 30W review – A 33-36W laser engraver tested with LightBurn

LASER LONGER B1 30W review

Today we will review the LONGER Laser B1 30W laser engraver with the LightBurn program. The machine is equipped with a laser module comprised of six 6W laser diodes for a total power of 33 – 36 W when accounting for some variation in the power delivered by each diode. The Laser B1 can cut through 20 mm thick wood and 10 mm thick black acrylic in just one cut, and with multiple passes, it can also handle up to 25mm thick wood 50mm thick black acrylic, and even 0.1mm thick stainless steel.
