Orange Pi 5 SBC gets its own $20 low-profile ICE Tower cooling fan

A few years ago I reviewed the ICE Tower CPU cooling fan for Raspberry Pi 4 which is an oversized heatsink with a cooling fan and some RGB LEDs that obviously does its job at cooling the board, but the main benefit is really its aesthetics. 52Pi has now designed another ICE Tower cooling fan for the Orange Pi 5 SBC, and the new Orange Pi 5B, with the same concept except for its low-profile design. It’s probably not needed for the Orange Pi 5 which should do fine with a heatsink, but it may help for the Orange Pi 5B due to the extra heat from the WiFi 6 module. A company representative for 52Pi told us that: I have seen this Orange Pi 5B motherboard posted on your site, there are quite a lot of reviews and discussions, so far after our engineer’s test, this motherboard has quite […]

PicoMQTT – An MQTT Client/Broker library for ESP8266 and ESP32

PicoMQTT is a lightweight MQTT library for Arduino/PlatformIO optimized for ESP8266 and ESP32. It not only supports the MQTT Client mode like most existing solutions but also the MQTT Broker mode which transforms an ESP8266 or ESP32 board into an MQTT gateway replacing a Raspberry Pi board or an IoT gateway typically used for this task.

The library follows MQTT 3.1.1 specification, supports the publishing and consuming of arbitrary-sized messages, can deliver thousands of messages per second, and supports easy integration with the ArduinoJson library to publish and consume JSON messages.

Using Pico:ed V2 board as a replacement for BBC Micro:bit

We’ve received a sample of the Pico:ed V2 board developed by ELECFREAKS and will show how to use it as a replacement for the BBC micro:bit in a project using CircuitPython. We’ve already covered the board in detail with specifications, block diagram, and pinout diagram before, and it’s basically a Raspberry Pi Pico RP2040 board with BBC Micro:bit form factor including a 17×7 Dot Matrix LED display, some buttons, a buzzer, but no wireless connectivity, relying only on USB instead. CircuitPython firmware installation on the Pico:ed V2 board The board supports C/C++, MicroPython, and CircuitPython programming languages, and for this review, we’ve decided to download the CircuitPython UF2 firmware. Press and hold the BOOTSEL button after having downloaded the firmware file… … and connect the board to your computer using a USB cable before releasing the BOOSEL button on the Pico:ed V2 board, which should then show up as the […]

Orange Pi 5B SBC adds up to 256GB eMMC flash, built-in WiFi 6 and Bluetooth 5.0 module

Orange Pi 5B is a variant of the Rockchip RK3588S powered Orange Pi 5 SBC with up to 256GB eMMC flash and a soldered-on wireless module offering WiFi 6 and Bluetooth 5.0 connectivity, at the cost of losing the M.2 2242 socket and 16MB QSPI NOR flash found in the original board. The board still comes with HDMI 2.1, DisplayPort 1.4 (USB-C), and MIPI DSI display connectors, three camera connectors, a Gigabit Ethernet interface, a few USB ports, and a 26-pin GPIO header for expansion. Orange Pi 5B specifications with the new features highlighted in bold, and the missing ones as strikethrough text: SoC – Rockchip RK3588S octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ up to 1.8 GHz, Arm Mali-G610 MP4 GPU, 6 TOPS AI accelerator System Memory – 4GB, 8GB, or 16GB LPDDR4/4x (32GB RAM is also listed, but not for […]

Aspinity AB2 AML100 Arduino Shield supports ultra-low-power analog machine learning

Aspinity AB2 AML100 is an Arduino Shield based on the company’s AML100 analog machine learning processor that reduces power consumption by 95 percent compared to equivalent digital ML processors, and the shield works with Renesas Quick-Connect IoT platform or other development platforms with Arduino Uno Rev3 headers. The AML100 analog machine learning processor is said to consume just 15µA for sensor interfacing, signal processing, and decision-making and operates completely within the analog domain offloading most of the work from the microcontroller side that can stay its lowest power state until an event/anomaly is detected. Aspinity AB2 AML100 Arduino Shield specifications: ML chip – Aspinity AML100 analog machine learning chip Software programmable analogML core with an array of configurable analog blocks (CABs) with non-volatile memory and analog signal processing Processes natively analog data Near-zero power for inference and events detection Consumes <20µA when always-sensing Reduces analog data by 100x Supports up […]
