Openviro Axe PoE is an RP2040-based environmental sensor for server rooms and cabinets (Crowdfunding)

Openviro Axe PoE is a rack-mountable, open-source environmental sensor designed to measure the temperature and humidity (and air pressure) in server rooms or cabinets with electrical equipment. The device is based on a Raspberry Pi RP2040 board with Ethernet connectivity housed in an aluminum enclosure and equipped with two RJ12 connectors for Bosch BME280 sensors with an accuracy of +/- 0.5°C. It provides better results than sensors placed in a machine that may be impacted by the internal components’ heat dissipation. For instance, the two sensor inputs can be used to measure the temperature and humidity of the intake and exhaust in a server rack. Openviro Axe PoE specifications: Microcontroller – Raspberry Pi RP2040 dual Arm Cortex-M0+ @133 MHz with 264 KB SRAM Storage – 16 MB flash memory Network – 10/100Mbps Ethernet RJ45 port via LAN8710Ai Expansion – 2x RJ12 connector for THP Probes Misc – 3x Buttons Power […]

Xero MCU is a compact USB-C board based on STM32F411 microcontroller (Crowdfunding)

Xero MCU is a small STMicro STM32F411 Arm Cortex-M4F microcontroller board with a USB-C port, twenty through and castellated holes for GPIOs, a Debug connector, Reset and Boot buttons, and a few LEDs. The 100 MHz MCU embeds 512KB flash and 128KB SRAM, and the board is said to be designed for hobbyists, students, and professionals. For reference, the Xero MCU board features the same STM32F411CEU6 microcontroller found in the Black Bill board. However, it’s quite shorter at about half the size, and features castellated edges, making it suitable for soldering on a baseboard. Xero MCU specifications: Microcontroller – STMicro STM32F411CEU6 Arm Cortex-M4F MCU @ 100MHz with 512KB Flash, 128KB SRAM USB – 1x USB Type-C port for power and programming Expansion – 2x 20-pin through and castelled holes with up to 17x GPIO, I2C, 2x SPI, 2x UART, 4x ADC, 5V, 3.3V, and GND Debugging – 4-pin debug connector […]

BPS is a GPS alternative working over ATSC 3.0 digital TV signals

Broadcast Positioning System (BPS) is an alternative to GPS designed for timing and positioning over ATSC 3.0 digital TV signals, and mainly designed as a backup solution for national security. GPS is critical in providing not only location data, but also timing data for critical infrastructure such as power grid, telecommunication networks, and so on. However, GPS signals can be spoofed, and/or satellites could potentially be damaged or even taken down. That’s where BPS comes in as an alternative with a much broader network of base stations, and both GPS and BPS signals can be compared, meaning it can be used to detect spoofing as well. It works by adding a preamble with timing data and a Data PLP (Physical Layer Pipe) with tower information and location. One tower is enough for timing data, and positioning will also be possible with four towers within range. Time accuracy is 100ns (95% […]
