New Raspberry Pi PoE+ HAT handles up to 25.5 Watts

The Raspberry Pi Foundation has just announced the Raspberry Pi PoE+ HAT compliant with 802.3at (aka PoE+) and 802.3af standards and support for up to 25.5 Watts input. It will replace the Raspberry Pi PoE HAT introduced in 2018 which was limited to 802.3af standard with a maximum of 15.4 Watts input and will become available around mid-June for $20 plus taxes and shipping. Raspberry Pi PoE+ HAT specifications vs PoE HAT. Besides supporting 802.3at standard with a higher current/more power, the new PoE+ HAT also adds a current sensor and relies on a planar transformer instead of a wire wound transformer with the former being more compact and efficient. The brushless fan is controlled by I2C and helps the processor on the Raspberry Pi 3/4. You may need the latest version of the Raspberry Pi OS for the new PoE+ HAT to work properly. While the Raspberry Pi PoE+ HAT […]

ESP32-WROOM-DA dual PCB antenna WiFi module aims for longer range, better reliability

Espressif Systems ESP32-WROOM-DA is another ESP32 based WiFI & BLE module with a twist as its dual PCB antenna design aims to provides a longer range and more reliable connectivity by automatically switching to a specific PCB antenna depending on signal strength. The new module features ESP32-D0WD-V3 dual-core Xtensa LX6 dual-core processor with a maximum frequency of 240 MHz, along with 520 KB of SRAM and 448 KB of ROM, and has been designed to be pin-to-pin compatible with ESP32-WROOM-32E module found in products such as Pico Wireless, in order to ease migration between the two modules. Espressif did not provide detailed specifications for the new WiFi module, but assuming it’s mostly based on ESP32-WROOM-32E design, ESP32-WROOM-DA should have the following key features & specifications: WiSoC – Espressif Systems ESP32-D0WD-V3 embedded, Xtensa dual-core 32-bit LX6 microprocessor, up to 240 MHz with 448 KB ROM for booting and core functions, 520 […]

Rock Pi 4 Plus SBC gets Rockchip OP1 processor, eMMC flash pre-loaded with Twister OS Armbian

The low-cost Rock Pi 4 SBC was unveiled in 2018 with a Rockchip RK3399 processor, up to 4GB RAM, and Raspberry Pi 3 form factor. Rock Pi 4 Plus builds on the relatively popular single board computer with an upgrade to Rockchip OP1 processor, which is a higher performance RK3399 SoC typically used in Chromebooks and ASUS Tinker Board 2. The new board also adds 16 to 128 GB eMMC flash, instead of relying on an optional eMMC module, and will come pre-loaded with Twister OS Armbian lightweight desktop OS based upon Armbian Focal 20.04.1 LTS (aarch64) for Rockchip RK3399-based SBCs. Four variants of Rock Pi 4 Plus share most of the same specifications: SoC – Rockchip OP1 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 2.0 GHz, 4x Cortex-A53 @ up to 1.4 GHz, a Mali-T864 GPU with support OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, DX11, and AFBC, and […]

Genmitsu 6060 XY-Axis Extension Kit for PROVerXL4030 – DIY desk and folding cart

Karl here. I teased this article in the final review of the Genmitsu PROVerXL 4030 CNC Router. I was really happy with the base kit. You can check out all my thoughts there. SainSmart recently released an extension kit that I have now had for a few weeks. It increases the stock size from 300 x 400 to 600 x 600. That is what we are here to check out today. When I inquired about the kit I didn’t realize how boring a review of the kit would be but I will do my best to bring some additional value beyond just unboxing and building experience. Unboxing The parts list is minimal 2x Y-axis Aluminum Extrusion (lead screw included) 2x X-axis Aluminum Extrusion (lead screw included) 2x Front/Back Plate 7x Drag Chain 9x Drag Chain 4x Hexagonal Wrench, 4mm, 3mm, 2.5mm, 1 mm The original kit came with some decent […]
