Review of SunFounder Raspberry Pi UPS Power Supply

SunFounder’s Raspberry Pi UPS Power Supply is a complete UPS kit for the Raspberry Pi 3/4 Model B/B+ with a PiPower board, a 2,000 mAh battery, and all accessories requires for the assembly. It also works with other Raspberry Pi-sized boards that support 5V DC input such as Banana Pi BPI-M5, Libre Computer ROC-RK3328-CC, and other similar SBCs. Many years ago, I bought a Raspberry Pi battery pack for review hoping that it would also work as a UPS, but it was not perfect as the board would sometime reboot during power failure simulations. Since then, there have been many UPS kits launched to the market, but I didn’t try any so far, so when SunFounder contacted CNX Software to review their “Raspberry Pi UPS Power Supply”, I took the opportunity, and I will report my finding in this review. Raspberry Pi UPS Power Supply key features UPS module output […]

Affordable RTK GNSS receiver supports USB or/and Ethernet interfaces (Crowdfunding)

HYFIX’s RTK Rover is an affordable, centimeter-accurate RTK (Real-time Kinematic) GNSS receiver with either a USB interface or/and Ethernet connectivity with the latter relying on a Raspberry Pi 4 SBC. As a reminder, RTK relies on traditional GNSS networks like GPS and works with a Base station at a fixed location and a Rover station that can be fitted to a drone or mobile robot in order to determine the position with up to one-centimeter accuracy. The RTK Rover from HYFIX is equipped with a dual-band LC29H GNSS module from Quectel and an onboard IMU sensor that tracks position through dead reckoning when GNSS connectivity is lost. RTK Rover specifications: MiniPCIe card with Dual-Band L1/L5 RTK Receiver (Quectel LC29H) Antenna – External antenna (6x5x2 cm) connected to SMA connector Sensor – IMU Interfaces USB Type-C port for power and serial Interface Ethernet Rover Kit only – Gigabit Ethernet and USB ports […]

LuckFox Core3566 – A Raspberry Pi Compute Module 4 alternative that sells for $24 and up

We’ve already seen Rockchip RK3566 system-on-modules that follow the Raspberry Pi Compute Module 4 with the likes of Pine64 SOQuartz and Radxa CM3. But there’s at least one more Raspberry Pi Compute Module 4 alternative based on the RK3566 SoC with the LuckFox Core3566 going for as little as $23.99. I found out about the new module after checking out the upcoming Orange Pi Compute Module 4 (another CM4 alternative based on RK3566), and the LuckFox Core3566 is offered with 2GB or 4GB RAM, an optional 32GB eMMC flash, and an optional WiFi 5 and Bluetooth 5.0 module. LuckFox Core3566 specifications: SoC – Rockchip RK3566 quad-core Cortex-A55 processor up to 1.8 GHz with a 32-bit RISC-V MCU, an Arm Mali-G52 GPU supporting OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, Vulkan 1.1, a 0.8 TOPS NPU for AI acceleration System Memory – 2GB to 4GB LPDDR4 Storage – Optional 32GB eMMC module Wireless module […]

Micro RP2040 is a tiny Raspberry Pi RP2040 module with a USB Type-C port, 28 castellated & through holes

SB Components’ Micro RP2040 is a tiny module based on the Raspberry Pi RP2040 Arm microcontroller with up to 23 GPIOs and a USB Type-C port for easy powering and programming. Ever since the Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller was released, companies have been making tiny modules based on it. Some come with a USB Type-C port such as the Pimoroni Tiny 2040 and the Adafruit QT Py RP2040 boards, while others focused on providing a smaller form factor for soldering only with design such as the RP2040 Stamp or the minuscule 12x12mm Femto module. The Micro RP2040 module comes with a USB-C port and more I/Os than competing modules thanks to a slightly larger 25 x 24.95mm design. Micro RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 264kB of SRAM Storage – 2MB QSPI flash USB – USB Type-C […]

ANAVI launches CircuitPython-programmable Macro Pad 12 & Arrows mechanical keyboards (Crowdfunding)

ANAVI Technology has launched two more open-source hardware mechanical keyboards based on the Raspberry Pi RP2040 microcontroller, equipped with an OLED display, and programmable with CircuitPython: the ANAVI Macro Pad 12 with 12 keys and the ANAVI Arrows with four keys and a rotatory encoder. The new mechanical keyboards follow ANAVI Macro Pad 10 & Knobs input devices equipped with the same Seeed Studio XIAO RP2040 MCU module running the KMK firmware written with CircuitPython, but with different form factors and features. ANAVI Macro Pad 12 specifications: MCU module – Seeed Studio XIAO RP2040 with Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 Mhz with 264KB SRAM, 2MB SPI flash, USB Type-C port Keys – 12x Gateron red, linear, non-clicky mechanical switches and transparent keycaps with yellow LED backlighting Display – OLED display connected to I2C slot (can be replaced with another I2C module) Host interface – USB […]

PiccoloBASIC – A BASIC interpreter for the Raspberry Pi Pico board

PiccoloBASIC is an open-source BASIC interpreter for the Raspberry Pi Pico development board that’s based on “uBASIC: a really simple BASIC interpreter” by Adam Dunkels and relying on Arm’s LittleFS fail-safe filesystem for microcontrollers. If my memory serves me well, my first computing experience was at school using a Thomson TO7 computer that we programmed with BASIC. I don’t think the language is still used in practical applications, but we can still see some BASIC projects pop up from time to time such as a BASIC interpreter for the Arduino Zero boards. Gary Sims, owner of the Gary Explains YouTube channel, has now ported a BASIC interpreter to the Raspberry Pi Pico. The project is still work in progress, but currently implemented features include: Let, if, print, for, goto, gosub String variables (let z$=”hello”) Floating point numbers and variables (let z#=1.234) Builtin functions [zero, randint, not, time] Sleep, delay, […]

8K 50MP camera module targets NVIDIA Jetson, Raspberry Pi, and RK3588 boards (Crowdfunding)

RBTS.co’s C50M camera module is equipped with the same 8K 50MP Samsung ISOCELL GN2 image sensor found in the upcoming Google Pixel 8 Pro smartphone but targets the maker market with support for NVIDIA Jetson, Raspberry Pi, and Rockchip RK3588 boards. With high-resolution and quick focusing ability, this camera sensor is designed for drones, machine vision, and industrial automation applications such as automated optical inspection and preventive maintenance, and the large 1.4μm pixels of the Samsung ISOCELL GN2 sensor are said to make the camera work well in low-light conditions. C50M camera module specifications: Effective Resolution – 8,160 x 6,144 (50MP) Pixel Size – 1.4μm (2.8μm with 12.5MP binning) Optical Format – 1/1.12″ sensor Color Filter – Dual Tetrapixel RGB Bayer Pattern Frame Rate – 30fps @ 50MP, 120fps @ 4K and 480fps @ FHD ADC Accuracy – 10-bits Chroma – Tetra Auto Focus – Dual Pixel Pro (PDAF); range: […]
