Orange Pi PC is an Allwinner H3 SBC that was launched in 2015 for as little as $15 plus shipping (now $17.42 with 1 GB RAM), and made by a company called Shenzhen Xunlong Software. The next year, the company launched Orange Pi PC Plus with 8GB eMMC flash and WiFI connectivity for $20 (now $25.54). It appears another company named “Shenzhen LC Technology” has designed a board with similar specifications & layout, so not technically a clone, but close enough. Meet Cherry Pi SBC. Cherry Pi PC V7 SBC specifications with highlights in bold or strikethrough showing the differences with Orange Pi PC: SoC – Allwinner H3 quad-core Cortex A7 processor with an Arm Mali-400MP2 GPU System Memory – 512MB or 1GB DDR3 Storage – MicroSD card slot up to 64GB, optional 8GB eMMC flash, Video Output – HDMI 1.4 and AV ports Audio I/O – HDMI, AV port, […]
Maker Pi Pico STEM board mini review with CircuitPython
In my early list of third-party Raspberry Pi RP2040 boards, I shortly mentioned Cytron Maker Pi Pico baseboard for Raspberry Pi Pico that exposes all pins via female headers, includes LEDs for all GPIOs pin, six Grove connectors, three user push-buttons, one RGB LED, a piezo buzzer, an audio jack, a MicroSD card, and an ESP-01 socket to add WiFi connectivity. The beta version sold for $5, and at the time I missed that included Raspberry Pi Pico board as well, so basically you got a free baseboard. The Malaysian company has now sent me a review sample to play around with, so let’s have a closer at the hardware and code samples for the board. Maker Pi Pico Unboxing and Specifications I received the board in Cytron package together with a pinout diagram for Raspberry Pi Pico, and we can see the latter is already soldered to Maker Pi […]
ESP32-PICO-V3-ZERO-DevKit targets Amazon Alexa Connect Kit (ACK) development
Last summer, Espressif and Amazon jointly announced the ESP32-PICO-V3-ZERO Alexa Connect Kit module providing out-of-box connectivity to ACK (Alexa Connect Kit) cloud services, support for features such as Alexa control, “Frustration-Free Setup” and Amazon Dash replenishment for connected devices. At the time, the module was still at the developer preview stage, and you had to create your own carrier board for the module. But now development has been easier with the companies launching ESP32-PICO-V3-ZERO-DevKit compatible with Arduino Zero development board. ESP32-PICO-V3-ZERO-DevKit specifications: Wireless module – Espressif Systems ESP32-PICO-V3-ZERO with ESP32-PICO-V3 System-in-Package (SiP) based on ESP32-V3 dual-core Xtensa LX6 WiFI and Bluetooth SoC, a 4 MB SPI flash, a crystal oscillator, filter capacitors, and an RF matching network. Expansion – Arduino Zero compatible pass-through headers Debugging – 1x micro-USB port Misc – Power & Status LEDs, Reset button, jumpers to route specific signals to the headers, DSN (Device Serial Number – […]
Kodi 19 “Matrix” released with AV1, HDR, tvOS support
Kodi is an open-source media center that was initially designed for the XBOX game console, but was quickly ported to other platforms such as Windows and Linux, and eventually to low-cost Android TV boxes and single board computers such as Raspberry Pi. A new stable release of the software comes out every couple of years, and the developers have just announced the release of Kodi 19 “Matrix” a little over two years after Kodi 18 “Leia” release. The default user interface may look similar to the one for Kodi 18, but there have been many changes over the last two years with some of the highlights including: Skin/Look-and-Feel Screen redesign, especially for music with new metadata displays and changes to playlist views New “now playing” view Artwork and image file improvements Video Playback AV1 software decoding Windows 10 – HLG HDR and static HDR10 playback Android – Static HDR10 and […]
PoE powered AI Edge computer combines NXP i.MX 8M SoC with Google Edge TPU
AAEON has introduced several BOXER AI edge computers over the years either powered by an NVIDIA Jetson module, a HiSilicon HI3559A Arm SoC, or an Intel processor combined with Movidius Myriad AI accelerator. The latest model, BOXER-8521AI, combines an NXP i.MX 8M SoC with Google Edge TPU AI accelerator, and offers 1GB RAM, USB ports, a 40-pin external I/O connector, and 12V or PoE power inputs.

LiPo battery powered Olimex boards use ESP32-S2’s USB OTG interface
Last year, Olimex introduced ESP32-S2-DevKit-LiPo and ESP32-S2-WROVER-Devkit-LiPo boards optimized for battery-powered applications with as little as 30uA deep sleep power consumption. ESP32-S2 processor comes with a USB OTG interface, but at the time, Espressif Systems ESF-IDF SDK did not support programming via the built-in USB interface, so Olimex added CH340T USB to serial converter for programming. The good news is that the SDK can now support USB programming without an external chip, so the company designed new versions of the boards without a USB to serial chip with namely ESP32-S2-DevKit-LiPo-USB and ESP32-S2-WROVER-Devkit-LiPo-USB boards. The specifications are basically the same as previously except for the removal of the USB to serial chip, support for USB OTG, and even lower power consumption: Wireless module: ESP32-S2-DevKit-LiPo – ESP32-S2-WROOM with Espressif ESP32-S2 single-core 32-bit LX7 microprocessor up to 240 MHz with 128 KB ROM, 320 KB SRAM, 16 KB SRAM in RTC, 4MB SPI […]
Android 12 developer preview released – What’s New?
Google releases a new version of Android every year, and the company is now usually releasing a developer preview in February to allow feedback and testing from app developers. So here we are with the Android 12 developer preview having just been released by Google with changes ranging from trust and safety to media transcoding to support for AVIF image format. Android 12 highlights: Performance Improved Binder IPC calls – Google engineers have had a look at latency and workload distribution, and made optimizations that reduce the median experience. This has yielded roughly a 2x performance increase on Binder calls overall, and up to a 47x improvement in refContentProvider(), 15x in releaseWakeLock(), and 7.9x in JobScheduler.schedule(). Foreground service optimizations – To ensure a better experience for users, foreground service starts from the background will be blocked for apps that are targeting the new platform. Android 12 will also delay the […]
ESP32 TouchDown comes with 3.5-inch display for custom control interfaces
Dustin Watts developed FreeTouchDeck software to interface with Windows, macOS, Linux computers and boards over Bluetooth LE using an ESP32 board connected to a touchscreen display. So far, he used off-the-shelf parts, but he has now decided to create his own hardware with ESP32 TouchDown open-source hardware board equipped with a 480×320 TFT display. ESP32 TouchDown specifications: Wireless Module – ESP32-WROOM-32D with ESP32 dual-core WiFi & Bluetooth processor, 4MB flash, PCB antenna Display – 3.5-inch 480*320 TFT screen based on ILI9488 driver connected over SPI mode, plus FT6236 Capacitive Touch Controller Storage – MicroSD card reader USB – 1x USB-C port Expansion Header with I2C, SPI, 7x GPIO, 3.3V and GND Stemma / JST-PH I2C connector Debugging – CP2102 USB-to-UART IC Misc – Piezo speaker, Power & Charge LEDs, on/off switch, boot and reset buttons, Power Supply 5V via USB-C 2-pin JST connector for battery APK2112 3.3V regulator MCP73831 battery […]
