Review of Blackview MP80 (Processor N97) mini PC with Windows 11 Pro

Review Blackview MP80 Processor N97

Blackview MP80 is a tiny pocket-sized mini PC powered by either an Intel Alder Lake-N Processor N95 or Processor N97 CPU with 16GB LPDDR5 RAM and a 512GB M.2 SSD preloaded with Windows 11 Pro. We’ve already reviewed the Blackview MP80 (N95) mini PC a few months ago, but the company has now sent us the Processor N97 model for review. Both models look identical with the same ports including three HDMI 2.0 video outputs, three USB ports, and two gigabit Ethernet ports, plus a Wi-Fi 5 and Bluetooth 4.2 wireless module. The mini PCs are also actively cooled, and the only obvious differences are the processor (Intel N95 vs N97) and the color of the enclosure. We usually do a three-part review with the first one listing the specs, and going through an unboxing and a teardown, but for the Blackview MP80 (N97) review we will do those and […]

Adafruit MEMENTO ESP32 S3

Adafruit’s new MEMENTO – Bare Board Camera module is powered by the ESP32-S3 and can be programmed with CircuitPython or Arduino. The module includes a camera with an OV5640 sensor which features auto-focus capabilities and the board includes a 1.54″ 240×240 Color TFT to display the images. Previously we have covered many ESP32-based camera modules like the TinyML-CAM, the Arduino Nicla Vision, TTGO T-Camera, and many other camera modules that feature the OV5640 sensor you can check those out if interested. Features and Specifications of the MEMENTO ESP32 Camera Module: Processing and Connectivity ESP32-S3 Module Dual-core 240MHz Tensilica processor 8 MB Flash, 2 MB PSRAM WiFi and BTLE capabilities Camera and Display OV5640 Camera Module 5MP sensor 72-degree view Autofocus JPEG encoder 1.54″ Color TFT Display with 240×240 resolution Storage – MicroSD card slot (SPI) Ports and Expansion Two Digital/Analog Stemma Ports – JST PH-3 connectors for A0, A1, power, […]

ODROID-M1S review – Part 1: Ubuntu 20.04, Vu8S touchscreen display, UPS Kit, and WiFi Module 5BK

ODROID-M1S review with UPS module and V8uS module

Hardkernel ODROID-M1S single board board was recently launched to celebrate the company’s 15th anniversary. While the ODROID-M1 board was introduced with the Rockchip RK3568 SoC last year, the new ODROID-M1S board is smaller and cheaper starting at just $49 and comes with a Rockchip RK3566 SoC. Hardkernel sent us a sample of the ODROID-M1S board for review with 8GB of memory and 64GB of storage as well as accessories. Let’s unpack the box before trying it out with Ubuntu 20.04 Desktop and testing each accessory. ODROID-M1S unboxing with ODROID-Vu8S display, UPS kit, and WiFi dongle The review package we received from Hardkernel included the ORDROID-M1S SBC in its plastic enclosure, the VU8S 8-inch touchscreen display, a UPS board, and a dual-band WiFi 5 USB dongle. The UPS module comes without a battery, so we had to find an 18650 battery to use it. As we’ll see further below, the UPS […]

SparkFun’s latest development board, the ESP32 Qwiic Pro Mini, puts the Espressif ESP32-PICO-MINI-02 on a compact Arduino Pro Mini footprint. It also includes an onboard QWICC connector for easy interfacing with a wide range of sensors and peripherals. We have already covered other Sparkfun dev boards like DataLogger IoT, Datalogger IoT – 9DoF, and SparkFun Thing Plus Matter you can check those out if interested. Like any other ESP32 board, this also uses an ESP32 microcontroller which features a 32-bit dual-core processor, 520kB of SRAM, 2MB of PSRAM, 8MB of flash memory, and 16 kB of additional SRAM in its RTC. It supports Bluetooth 4.2 and BLE and has ADC and DAC, touch detection, PWM, TWAI, Ethernet MAC, UART, SPI, SDIO, I2C, and I2S interfaces. As reported in a Hackster article, the board also features a Qwiic Connector for solderless connections to sensor boards and add-ons, positioned at a 90-degree angle […]

Microflex MCUs – Tiny USB development boards based on ESP32-S3, ESP32-S2, ESP32-C3, ESP32-C6, or Raspberry Pi RP2040 (Crowdfunding)

Microflex MCU board with ESP32 and RP2040 microcontrollers

SB Components is back with yet another crowdfunding campaign this time with the Microflex MCUs USB development boards all with the same tiny form factor and offered with a choice of five microcontrollers namely Raspberry Pi RP2040, ESP32-S3, ESP32-S2, ESP32-C3, or ESP32-C6. Microflex MCUs share the same layout with a USB-C port for power and programming, a built-in RGB LED, two buttons for Boot and Reset/User, and two rows of 10-pin with through and castellated holes to access the GPIOs and power signals such as 5V, 3.3V, and GND. But they differ in terms of the processor used, wireless features, and available I/Os as shown in the table below which sadly lacks any information about the flash and eventual PSRAM… The illustration below includes some more details for the Micro-C6 with the main components, ports, and a pinout diagram. Programming the firmware for the ESP32-series can be done through the […]

Radxa Zero 3W SBC – Rockchip RK3566 SoC, 8GB RAM, WiFi 6 in Raspberry Pi Zero 2 W form factor

RADXA Zero 3W

More Raspberry Pi Zero 2 W lookalikes are coming to market, as after the Allwinner H618-based Orange Pi Zero 2W, the Radxa Zero 3W has now been introduced with a 1.6 GHz Rockchip RK3566 processor and up to 8GB RAM, plus WiFi 6 and Bluetooth 5.4 connectivity, which makes it one of the most powerful Arm Linux SBCs in the compact Raspberry Pi Zero form factor. The board also comes with an optional eMMC flash with up to 64GB capacity, a microSD card, a micro HDMI port, two USB Type-C ports, a MIPI CSI camera connector, and of course, the usual 40-pin Raspberry Pi GPIO header. Radxa Zero 3W specifications: SoC – Rockchip RK3566 CPU – Quad-core Arm Cortex-A55 processor @ 1.6 GHz (Note the RK3566 is usually clocked at up to 1.8 GHz but may have been underclocked here due to heat issues at the higher frequency as the […]

ESP32 may soon get an open-source WiFi MAC layer

ESP32 open-source WiFi MAC driver

Most, if not all, WiFi hardware relies on closed-source binary blobs including ESP32 wireless MCU, but there’s now work underway to reverse engineer a WiFi MAC layer for the ESP32 to make it a truly open-source platform. Espressif ESP32 wireless microcontrollers already have an open-source framework (ESP-IDF) and toolchain, people can customize the code to some extent, but this excludes the wireless bits (Wi-Fi, Bluetooth, low-level RF functions) that are distributed as closed-source precompiled libraries integrated into the firmware. There were some efforts to provide an open-source stack for the BL602 chip but it never went anywhere, and the ESP32 may become the first target with an open-source driver without any blobs, excluding FPGA-based projects such as OpenWiFi. The early-stage implementation currently supports the following features: Sending WiFi frames Receiving WiFi frames Send an ACK packet as a reply to packets that are sent to the ESP32 Connect to an […]
