NanoPi M4V2 Kit Review – Part 2: FriendlyCore Desktop

We’ve already seen how to assemble NanoPi M4V2 metal case kit which offers an Arm mini PC solution with support for NVMe SSD. The new NanoPi M4V2 Rockchip RK3399 SBC is an evolution of the M4 board that brings faster LPDDR4 memory and adds power & recovery buttons. Since we’ve already tested several RK3399 SBC‘s and TV boxes, I planned to focus the review on thermal design evaluation (i.e. see how well the board cools), and see how memory bandwidth evolved from LPDDR3 to LPDDR4. I wanted to do so both with Linux and Android, since I could compare NanoPC-T4 (LPDDR3) benchmarks in Android. But this requires an eMMC flash module, and I don’t own any. So instead I planned to run Armbian because of support for armbian-monitor for nice temperature chart but it’s not working just yet, so instead I’ve done all tests with FriendlyCore Desktop (rk3399-sd-friendlydesktop-bionic-4.4-arm64-20190926.img) based on […]

Another GD32 RISC-V Development Kit with LCD By Seeed Studio

Recently we highlighted the $5 Longan Nano, a development kit released by Sipeed for the Gigadevice GD32V RISC-V family of microcontrollers. The Sipeed Longan Nano is powered by the GigaDevice’s GD32VF103CBT6, based on Nucleisys Bumblebee kernel (support RV32IMAC instruction sets and ECLIC rapid interrupt). Seeed Studio is currently on this quest for expanding the Gigadevice GD32V RISC-V ecosystem with the launch of the SeeedStudio GD32 RISC-V kit with LCD. The Seeed Studio development kit is based on the SeeedStudio GD32 RISC-V Dev Board and a 2.8 inch 240×320 pixel resistive LCD screen. The Seeed Studio GD32 RISC-V Dev Board is based on the 32-bit general-purpose GD32VF103VBT6 MCU, which can run at up to 108MHz. It comes with a 128KB on-chip Flash memory, and a 32KB SRAM memory. The development board comes with a total of 80 GPIOs, an onboard 8MB Flash and 256 Byte EEPROM, a staggering amount resources for this […]

Khadas VIM3L SBC Review with Android 9 Firmware

Khadas VIM3L is the first and so far only Amlogic S905D3 SBC on the market, so I first ran some benchmarks and checked system info. But it is also designed to be an HTPC, I’ll continue the review with some 4K video and audio playback testing, some gaming, and I/O benchmarks. Khadas VIM3L Unboxing As you may remember (or not), VIM3L ships either as a bare board pre-loaded with Android 9 or as an HTPC kit with the board running CoreELEC. I’ve received the bare board which also comes with two WiFi antennas. It can do much more than a simple TV box however, since it also comes with an M.2 NVMe socket (extra adapter board required), and sockets with MIPI DSI + touchscreen, and MIPI CSI camera. It’s one of the few boards with a low profile Ethernet connector, so if you ever wanted to build a farm of […]

STMicroelectronics Introduces Affordable LoRa Development Packs For All User Types

STMicroelectronics has recently announced the launch of a new set of LoRa Development packs, which are not only affordable, but they are aiming to a large pool of users from big organizations, small companies, hackers, engineers, students, and hobbyists. The ready-to-use development packs are aimed for applications bent on leveraging LoRa ’s long-range, low-power wireless IoT connectivity for tracking, positioning, metering, and many related applications. STMicroelectronics is releasing the P-NUCLEO-LRWAN2 pack and P-NUCLEO-LRWAN3 pack. Both packs provide a complete LoRaWAN development kit, and they include gateways, end-nodes, and ST tools, which are all based on the STM32 Nucleo evaluation boards. The LoRa gateway on both packs is based on the STM32 Nucleo-144 development board, NUCLEO-F746ZG. The STM32 Nucleo-144 development board with STM32F746ZG MCU supports Arduino, ST Zio, and Morpho connectivity. The Gateway header pins are exposed out to facilitate more development, and they support interfacing with LoRaWAN network-server providers LORIOT, Actility, myDevices Cayenne for LoRa […]

Khadas VIM3L (Amlogic S905D3) Benchmarks, Settings & System Info

Khadas VIM3L is the first Amlogic S905D3 SBC on the market and is sold as a lower-cost alternative to the company’s VIM3 board with a focus on the HTPC / media player market. Shenzhen Wesion was kind enough to send me a sample for review, and I’ll start by checking out benchmarks and system information in Android 9.0 Pie operating system. I also plan to perform a more detailed review with Android 9.0 and CoreELEC with a focus on media playback. I received the bare board only, and the first thing I did was to install it the heatsink I received for VIM3 and in turn, install it in the acrylic case. The company told me the heatsink is not really necessary “for normal purpose using like watch TV”, but it should be installed for performance tests and heavy workloads. I’d still recommend purchasing the heatsink to make sure it […]
