Raspberry Pi Power Management HAT Adds RTC, Battery Management, Software On/Off

Raspberry Pi Power Management HAT

If your Raspberry Pi project runs on battery, but may not need to be turned on 24/7 in order to lower power consumption, you’d have to find a way to schedule on and off times, and power off the board cleanly either when the battery is almost depleted, or your timer requires it There’s no built-in support for this in any of the Raspberry Pi boards, but Waveshare Power Management HAT can help you do just that since it adds an RTC, and enables software-controlled power timers and battery monitoring via an Arduino compatible ATmega328 MCU. Power Management HAT specifications: MCU – Microchip ATmega328P-AU MCU Storage – CAT24C32 EEPROM USB – 1x micro USB port for serial communication via CP2102 UART to TTL chip RPi Interface – 40-pin Raspberry Pi GPIO header Misc NXP PCF8523 RTC & calendar chip + CR1220 battery holder DEBUG switch (9) to either: Power directly […]

Nebula Cosmos Max 4K Video Projector is Powered by Amlogic T962X2 Processor (Crowdfunding)

Cosmos Max 4K Projector with Amlogic T962X2

Amlogic recently launched its first Cortex-A55 processors for TV boxes with S905X3, S905Y3 & S905D3 quad-core processors, but as noted by one commenter Amlogic already had some other Cortex-A55 processor specifically designed for TVs and projectors: T950X2 for full HD systems, and T962X2 for 4K UHD systems. Most smart TVs and projectors don’t advertise which chip they are using internally but I’ve just come across Anker Nebula Cosmos Max 4K home theater/video projector featuring Amlogic T962X2 processor. Based on the illustration below they also have a Full HD model based on the same processor. But I’ll focus on the 4K model in this post. Anker Nebula Comos Max key features & specifications: SoC – Amlogic T962X2 quad-core Cortex-A55 processor @ 1.9 GHz with Arm Mali-G31MP2 GPU System Memory – 2GB RAM Storage – 16GB eMMC flash Projector 0.47″ DMD chip 4K UHD resolution (3840×2160) 30″ to 150″ display 1500 ANSI […]

UP Xtreme Edge (UPX-Edge) Embedded Computer is Built around UP Xtreme Whiskey Lake SBC

UPX Edge Embedded Computer

AAEON UP Xtreme SBC was launched last June with a choice of 15W Whiskey Lake processors, namely Intel Celeron 4305UE dual-core processor, Intel Core i3-8145UE dual-core 4-thread processor, Intel Core i5-8365UE / Core i7-8665UE quad-core 8-thread processors. The company has now launched a complete embedded computer built around UP Xtreme SBC named UP Xtreme Edge Computing System, or simply UPX-Edge for short, that’s a slight variation of the fanless chassis offered for the SBC during the Kickstarter campaign. UPX-Edge specifications: SoC (one or the other) Intel Celeron 4305UE dual-core processor @ up to 2.2 GHz with 2MB cache, Intel UHD 610 graphics Intel Core i3-8145UE dual-core 4-thread processor @ up to 2.1 GHz / 3.9 GHz (Turbo) with 4MB cache, Intel UHD 620 graphics Intel Core i5-8365UE quad-core 8-thread processor @ up to 1.6 GHz / 4.1 GHz (Turbo) with 6MB cache, Intel UHD 620 graphics Intel Core i7-8665UE quad-core […]

BOKRA NXP LPC824 and Nordic nRF52832 powered MCU Modules Follow MikroBUS Form Factor

We first wrote about MikroElectronika MikroBUS socket in 2015 while covering an SBC which featured one MikroBUS socket supporting one of the 150 Click boards available at the time. There are now over 700 Click boards to choose from, with the tiny modules offering motor drivers, buttons, short-range connectivity,  UART and other interfaces, as well as various sensors. But BOKRA had another idea: developing MCU based systems-on-module following MikroBUS form factor. BOKRA LPC824 Lite module The first of those modules is BOKRA LPC824 Lite with the following specifications: MCU – NXP LPC824M201JHI33 Arm Cortex-M0+ microcontroller @ 30 MHz with 32KB Flash Memory, 8 KB RAM I/O MikroBUS headers with SPI, I2C, UART, PWM, GPIOs 10-pin “Serial” header 4-pin I2C Grove connector for Seeed Studio I2C Grove modules Debugging interface – SWD Misc – Reset button, power LED, 2x user LEDs Power Supply – 5V/500mA via MIC5528 regulator Dimensions – 28.6 […]

NORVII IIoT ESP32 Industrial Controller Comes with Built-in OLED or TFT Display, DIN Rail Mount

NORVI IIOT ESP32 Industrial Controller

We’ve previously covered at least one ESP32 industrial controller with TECHBASE Moduino X equipped with digital and analog I/O terminals, a 0.96″ OLED display,  and support for various expansion cards for RS-485, LoRa, Sigfox… beside Ethernet, WiFi, and Bluetooth connectivity offered by the Espressif Systems chip. NORVII IIOT industrial controller – based on ESP32-WROOM-32 module – offers many of the same options as the TECHBASE model, but also integrates a choice of 0.96″ to 1.44″ OLED or TFT display, and comes with plenty of LED’s to ease troubleshooting. There are five variants from three series (AE01, AE02, and AE03) sharing the following specifications: Wireless Module – ESP32-WROOM32 with ESP32 dual-core processor @ 160 MHz,  520 Kbytes SRAM / 4 Mbit Flash, WiFi 802.11 b/g/n Bluetooth 4.2 Storage – Optional microSD card slot Display -Built-in 0.96″ OLED display. 0.96″ TFT display or 1.44″ TFT display Communication – RS-485, WiFi, Bluetooth, optional […]

Trion T20 BGA256 FPGA Development Kit Supports “PulseRain Reindeer” RISC-V RV32IM soft CPU

Trion T20 BGA256 Development Kit

A few months ago I wrote about FireAnt low-cost FPGA development board powered by Efinix Trion T8 FPGA, and it was the first time I personally heard about the company. Trion FPGA family range from the T4 with 3,888 logic elements up to the Trion T200 with 192,000 LE’s. A board more powerful than FireAnt, but not quite high-end, recently showed up on Digikey with Trion T20 BGA256 development kit going for $150. Trion T20 BGA256 Development Kit specifications: FPGA – Efinix Trion T20 FPGA with 19,728 LE’s, 1,044 Kbit embedded RAM, 36 18×18 multipliers, 7 PPL’s, up to 220 GPIO’s; 256-ball FBGA (13×13 mm) System Memory – 256 Mbit SDR SDRAM Storage – NOR flash USB – 1x Micro-USB port for programming Debug / Configuration – SPI and JTAG headers to facilitate configuration Expansion 3x I/O headers to connect to external devices LVDS TX header, LVDS RX & clock […]

OpenWiFi Open-Source Linux-compatible WiFi Stack Runs on FPGA Hardware

OpenWiFi

WiFi is omnipresent on most connected hardware, and when it works it’s great, but when there are issues oftentimes they can not be solved because the firmware is a closed-source binary. I understand companies do that either to protect their IP and/or make sure end-users do not break FCC compliance. OpenWiFi project aims to deliver a completely open-source SDR (Software Defined Radio) WiFi implementation compatible with Linux and running on FPGA hardware. OpenWiFi currently supported features: 802.11a/g; 802.11n MCS 0~7; 20MHz Mode tested: Ad-hoc; Station; AP DCF (CSMA/CA) low MAC layer in FPGA Configurable channel access priority parameters: duration of RTS/CTS, CTS-to-self SIFS/DIFS/xIFS/slot-time/CW/etc Time slicing based on MAC address Easy to change bandwidth and frequency: 2MHz for 802.11ah in sub-GHz 10MHz for 802.11p/vehicle in 5.9GHz The developers tested OpenWiFi on Xilinx ZC706 FPGA evaluation kit coupled Analog Devices fmcomms2/fmcomms4 RF board to form an access point, and connected it to […]
