Beelink BT4 Mini PC Review – Slow, Buggy, Fan-cooled, and Overheating

Intel’s low-cost chip shortage has been so bad that Beelink has had to demothball some Atom chips when creating their new mini PC the Beelink BT4. This is one of the cheapest new mini PCs recently launched and uses the somewhat now old Cherry Trail Intel Atom x5-Z8500 CPU which was launched at the start of 2015 and is a quad-core 4-thread 1.44 GHz processor boosting to 2.24 GHz with Intel’s HD Graphics. The BT4 is the same form factor as the more recent Beelink mini PCs being a half-thick ‘NUC’ style device physically consisting of a 120 x 120 x 22 mm (4.72 x 4.72 x 0.87 inches) plastic rectangular case. This is not a passive device as it contains a small fan that stays on after the device has been shut down. The front panel has only a blue ‘power’ LED and the rear panel includes the power […]

Espressif Systems ESP32 Gets Bluetooth LE 5.0/5.1 Certifications

Espressif Systems ESP32 was introduced in 2016, and one of the key differences between ESP8266 and ESP32 was that the latter supported Bluetooth 4.2. But since then, the Bluetooth Special Interest Group (SIG) released Bluetooth 5.0 (2016) with higher speeds and longer range, and Bluetooth 5.1 (2019) adding direction finding for indoor positioning applications. One would have thought that upgrading from Bluetooth 4.2 to Bluetooth 5.0/5.1 might have required a new radio, but apparently not. As you can see from the above link and screenshot, ESP32 is now Bluetooth LE 5.0-Certified having passed SIG Bluetooth LE 5.0 certification. That means the Bluetooth protocol version supported by the ESP32 microcontroller has been upgraded from Bluetooth LE 4.2 to Bluetooth LE 5.0 with improved stability and compatibility. Another link also shows Bluetooth 5.1 certification for ESP NimBLE Host stack. Sadly that does not mean ESP32 suddenly supports the longer range and higher […]

Kobol Helios64 RK3399K SBC & 5-Bay NAS Pre-Orders to Start Next Week

We covered Rockchip RK3399K processor a few months ago, as a version of RK3399 processor qualified to run at 2.0 GHz, or supporting a wider-temperature range (-20 to +85°C) at 1.8 GHz. We found out about the new processor, as Kobol was working on a Helios64 SBC designed for NAS that featured RK3399K SoC. At the time, we just had a drawing of the board and some specifications, but now the company has announced pre-orders for the board and a complete 5-bay NAS kit will start next week and the actual shipping start in March. Kobol Helios64 SBC Specifications: SoC – Rockchip RK3399K hexa-core processor with 2x Arm Cortex-A72 cores @ 2.0 GHz, 4x Cortex-A53 cores @ 1.6 GHz System Memory – 4GB LPDDR4 Storage – 16GB eMMC 5.1 flash, 5x SATA 3.0, 1x M.2 SATA slot shared with one SATA 3.0 port, MicroSD port Connectivity – 1x 2.5GbE port, […]

Google Coral mPCIe and M.2 Cards for Sale, New Coral Dev Board Mini and Modules Coming in 2020

Google introduced Coral development board and USB accelerator with Google Edge TPU last year. The development board was comprised of a baseboard and Coral system-on-module with an NXP i.MX 8M quad-core Arm Cortex-A53 processor and the Edge TPU. Since then ASUS announced Tinker Edge T and CR1S-CM-A SBC based on the Coral module, and yesterday, I noticed Seeed Studio started selling mPCIe and M.2 AI accelerator card with Google Edge TPU, while today, Google announced upcoming Coral products for 2020. Coral Mini PCIe and M.2 Accelerators Coral Mini PCIe card specifications: Half-mini PCIe card with PCIe Gen2 x1 Supply voltage – 3.3VDC +/- 10 % Dimensions – 30.00 x 26.80 x 2.55 mm Weight – 3.6 g Temperature Range – Storage: -40 ~ 85°C; operating: -20 ~ 70°C Relative humidity – 0 ~ 100% (non-condensing) Op-shock – 100 G, 11ms (persistent); 1000 G, 0.5 ms (stress); 1000 G, 1.0 ms […]

DV8845 Amlogic S905C1 Android TV Hybrid Set-top Box Comes with DVB-T2 or DVB-C Tuner

A couple of weeks ago, we wrote about SDMC DV8919 TV box with Amlogic S905X4 processor capable of decoding 4K AV1 videos beside the usual H.265, H.264, and VP9 codecs. But it turns out the company has other devices based on a “new” Amlogic S905C1 processor, namely two hybrid set-top boxes running Android TV and equipped with either a DVB-T2 tuner (digital terrestrial TV) or a DVB-C tuner (cable). DV8845 specifications: SoC – Amlogic S905C1 quad-core Arm Cortex-A55 processor @ up to 2.0 GHz with Arm Mali-G31MP2 @ 850 MHz supporting OpenGL ES3.2, Vulkan 1.1 and OpenCL 2.0, and optional 1.2 TOPS NN inference accelerator System Memory – 2GB DDR memory (options: 1GB or 4GB) Storage – 8GB eMMC flash (options: 16GB, 32GB, 64GB) Video & Audio Output – HDMI 2.1 up to 4K @ 60+Hz with CEC & HDCP2.2, AV output with composite video and stereo audio Video Playback […]

Xiaomi Smart Multi-mode Gateway Supports Zigbee 3.0, WiFi, Bluetooth, and Bluetooth Mesh

Xiaomi has introduced several inexpensive home automation products over the years, often under their Mijia brands with for example a WiFi to IR blaster, a Zigbee & WiFi smart home kit, a smart door lock, or a smart speaker among other products. Recently, the company has launched the Xiaomi Smart Multi-mode Gateway that supports Zigbee 3.0, WiFi, Bluetooth, and Bluetooth Mesh.

Polos GD32V Alef is a Tiny RISC-V MCU Board Selling for $3

We first found out about GigaDevice GD32V 32-bit RISC-V MCU last summer, as an update/alternative to the earlier STM32 compatible GD32 Arm Cortex-M3 microcontroller from the company with higher performance and lower power consumption, while keeping the price identical. The first low-cost GD32V development board we covered was Longan Nano going for $5 with an OLED display and an acrylic case. If you don’t need either or want to access all pins from the 48-pin MCU, you can now order an even cheaper GD32V RISC-V MCU board with Polos GD32V Alef going for $2.99 on Analoglamb website. Polos GD32V Alef board specifications: MCU – Gigadevice GD32VF103CBT6 32-bit RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM USB – 1x micro USB OTG port for power and programming Expansion – 52 through holes (2.54mm pitch) exposing all pins from the MCU including 3x USART, 2x I2C, 3x SPI, 2x […]

Year 2019 in Review – Top 10 Posts and Stats

2019 is closing to an end, or you may already be into 2020 while reading this post. In any case, that means it’s time to look back at 2019 and look forward to the events and new products to take place next year. While 2018 was a boring year for new processors, 2019 brought us some interesting new chips such as Amlogic S922X / A311D, or the first Arm Cortex-A55 only processors such as Amlogic S905X3. Rockchip RK3399Pro was promising when it was announced last year, but it never really took off. It was a pretty quiet year for Allwinner as well. RISC-V architecture has been ramping up with the first general-purpose RISC-V MCU: GD32V, WCH CH572 Bluetooth LE MCU, the launch of more SiFive RISC-V cores, and Kendryte K210 RISC-V AI processor announced last year has found its way into more and more boards. There have also been the […]
