Raspberry Pi UPS HAT takes two 18650 batteries (Crowdfunding)

Raspberry Pi UPS solutions have been available for years with products like PiJuice Zero, PiVoyager, or LiFePO4wered/Pi+. But the team at SB Components has designed another UPS HAT for Raspberry Pi with a holder for two 18650 batteries. The HAT is designed for 5V operation up to 2.5A, connects with the Raspberry Pi SBC through the I2C bus from the 40-pin GPIO header, and is equipped with a 0.91-inch OLED for information display. UPS HAT for Raspberry Pi specifications: Power Input – 8.4V/2A via DC jack Power Output – 5V up to 2.5A through LDO chip (GPIO header and 2x USB ports) Display – 0.91-inch OLED Host interface – I2C Misc – On/Off switch Battery support 18650 Lithium battery (not included) via holder for two batteries Battery reverse indicator Charging and voltage monitoring via TI INA219 I2C chip Battery voltage balancing with Hycon HY2213 Battery protection IC (Hycon HY2120) Dimensions […]

Phased out Raspberry PI CM4 quad SATA carrier board becomes open-source hardware

Wiretrustee carrier board for Raspberry Pi CM4 was unveiled about one year ago with four SATA connectors to help people build their own 4-bay NAS. Unfortunately, the company decided to discontinue the project due to the semiconductors market situation. The good news is the board is now open-source hardware with all resources shared publicly including the Allegro schematics and PCB layout, Gerber files, 3D models for the heatsink, and case designs for 2.5-inch or 3.5-inch drives. All files are available under “CERN Open Hardware Licence Version 2 – Permissive”. Here’s a quick reminder about the Wiretrustee board specifications: Supported SoM – Raspberry Pi Compute Module 4 and 4 Lite Storage 4x SATA 2.0 via Marvell 88SE9215 (PCIe 2.0 x1 to 4 6Gb/s SATA ports, no HW RAID) MicroSD card slot Video Output – HDMI 2.0 up to 4Kp60 Networking – 1x Gigabit Ethernet port USB – 2x USB 2.0 ports […]

Manufacturing samples of Xassette-Asterisk open-source hardware board

We covered Xassette-Asterisk open source-hardware Allwinner D1s RISC-V Linux SBC last October. But it will most likely never be mass-manufactured since SdtElectronics, the designer, has no resources and time for production. So I thought I should give it a try, and I managed to get 10 boards manufactured and assembled. Time for a little disclaimer. While the post is not sponsored in the sense I did not get paid for it, NextPCB agreed to cover all costs, aka sponsor, and manufacture ten boards. Today, I’ll report my experience manufacturing an open-source hardware board, but I had no time to check whether any of the boards worked. Manufacturing timeline Since I did not want to go through the whole process of ordering the PCB, purchasing the components, and soldering each board individually, I opted for NextPCB’s PCB manufacturing and assembly services. Here’s the detailed timeline: November 9 – Ordered 10 boards […]

ESP32 UWB board features DW1000 module for accurate indoor positioning

FiRa “Fine Ranging” UWB technology was introduced a few years ago and is now found in devkits and Apple U1 chip. Makerfabs ESP32 UWB board provides another option with Espressif ESP32-WROVER-32 or ESP32-WROOM-32 WiFi & Bluetooth module combined with a Decawave DW1000 module for precision tracking. Makerfabs explains the board acts like a continuously scanning radar that locks onto another device (called Anchor, since it’s usually in a fixed location) and communicates with it to determine the distance between objects by calculating the time of flight (ToF) between devices, or in other words, the roundtrip time of challenge/response packets. ESP32 UWB board specifications: Wireless modules: WiFi & Bluetooth LE – ESP32-WROVER-32 or ESP32-WROOM-32 module with ESP32 dual-core processor @ 240 MHz UWB – B&T BU01 module based on Decawave DW1000 chip; IEEE802.15.4-2011 UWB compliant wireless transceiver module with a precision of 10cm indoors, a data rate of up to 6.8 […]

Qualcomm IPQ8072A networking SBC supports dual 10GbE, WiFi 6

DR8072 V01 is a networking SBC based on Qualcomm IPQ8072A communication processor, with two 10GbE interfaces, one through an SFP cage and the other through an RJ45 connector, plus four Gigabit Ethernet ports, and 4×4 MIMO WiFi 6 connectivity (AX3700). Based on Qualcomm AP.HK09 reference design, the board follows Wallys Communications’ DR8072A embedded router board introduced earlier this year, also based on Qualcomm IPQ8072, but equipped with two 2.5 GbE interfaces and WiFi 6 connectivity. DR8072 V1 specifications: SoC – Qualcomm Atheros IPQ8072A quad-core Arm Cortex-A53 @ 2.2 GHz part of Qualcomm Networking Pro 1200 Platform System Memory – 512MB DDR4 2400MHz 16-bit interface (option up to to 2GB RAM) Storage – 8MB NOR flash, 256MB NAND flash Networking Wireless On-board 4×4 2.4GHz MU-MIMO OFDMA 802.11b/g/n/ax, max 17dBm per chain, up to 1147Mbps On-board 4×4 5GHz MU-MIMO OFDMA 802.11a/n/ac/ax, max 17dBm per chain, up to 2475Mbps Frequencies – 2.412 to […]

UP Xtreme i11 Edge Compute Enabling Kit Review – Part 1: Unboxing and Teardown

AAEON’s UP Xtreme i11 Edge Compute Enabling Kit is an industrial mini PC based on the UP Xtreme i11 Edge single board computer powered by a choice of Tiger Lake processors and designed for edge applications for the industry. I recently got contacted by AAEON who sent me a version of the Edge Compute Enabling Kit with an Intel Core i7-1185GRE SoC, 16GB RAM, and a 128GB SSD pre-loaded with Ubuntu. I’ll start the review by checking out package content and interfaces, and teardown the hardware, before testing is with Ubuntu next month. UP Xtreme i11 Edge Compute Enabling Kit unboxing Customs took a keen interest in the package, opened it to check it out, and resealed it. But I eventually got the package, and customs their money… The package includes a 12V/6A power supply together with a power cord, EU type in my case, but the company will ask […]

DIY Pip-Boy wrist computer is equipped with Adafruit Feather RP2040 board

The Pip-Boy is a (virtual) personal information processor found in Fallout post-apocalyptic role-playing video games. But John Edgar Park decided to bring the wrist computer to (real) life combining an Adafruit Feather RP2040 board, a round IPS TFT color display, directional buttons, a joystick, and a battery. The Raspberry Pi RP2040 based Pip-Boy is programmed with CircuitPython and the demo code is a slide-show with navigation controls, but you could obviously adapt the code to your needs. The main components are: Black Adafruit Feather RP2040 board Adafruit Joy FeatherWing adding buttons and a joystick Adafruit 1.69″ 280×240 Round Rectangle Color IPS TFT Display FeatherWing Tripler mini kit to connect the two boards above and the display 3D printed enclosure A 3.7V/420mAh LiPo battery for power On/off switch The design is completed with some headers, stand-offs, screws, and a nylon watch strap. You’ll find detailed instructions with the list of parts, […]
