Wio Terminal Features Microchip SAMD51 MCU, Dual-Band WiFI & Bluetooth WiFI, and 2.4″ LCD

Microchip SAM D5x Arm Cortex-M4 microcontrollers were introduced in 2017, and the next year we started to see Arduino or MicroPython compatible board brought to market including Adafruit Metro M4 or Tachyon boards. Seeed Studio has now introduced its own Arduino & MicroPython compatible SAMD51 platform with Wio Terminal also integrating an RTL8720DN dual-band WiFi 4 and Bluetooth 5.0 chip, and 2.4″ LCD display. There are also Grove connectors to add sensor modules, and a 40-pin header to use the device like a Raspberry Pi HAT. Wio Terminal features and specifications: MCU – Microchip SAMD51 (ATSAMD51P19) Arm Cortex-M4F microcontroller @ 120 MHz (can be overclocked to 200 MHz) with 192KB RAM, 512KB flash Storage – 4MB external SPI flash, MicroSD card slot up to 16GB Display – 2.4″ LCD screen with 320×240 resolution (ILI9341 driver) Audio – Microphone and buzzer Connectivity – Dual-band WiFi 4 802.11b/g/n and Bluetooth 5.0 via […]

ODYSSEY-X86J4105800 SBC Combines Intel Gemini Lake SoC and Arduino Compatible MCU

Would it be good to have an all-in-one Windows platform used to both develop Arduino code and run that code to control I/O of your project? Or alternatively, have a single board computer capable of video processing and real-time I/Os? That platform already exists. UDOO X86 II SBC features an Intel Braswell processor combined with an Arduino Leonardo compatible Microchip ATmega32U4 MCU. But there’s now another, more powerful option courtesy of Seeed Studio with the oddly named ODYSSEY-X86J4105800 SBC equipped with an Intel Celeron J4105 quad-core Gemini Lake processor to run Windows 10 or Linux distributions, and a Microchip SAMD21 ARM Cortex-M0+ microcontroller compatible with Arduino Zero. ODYSSEY-X86J4105800 SBC specifications: SoC – Intel Celeron J4105 quad-core processor @ 1.5/2.5 GHz (Turbo) with 12EU Intel UHD Graphics 600 @ 250-750 MHz; 10W TDP System Memory – 8GB LPDDR4 RAM Storage Optional 64GB eMMC flash (fitted to ODYSSEY-X86J4105864 model), 1x SATA III data […]

Seeeduino Crypto Board Combines Microchip ATmega4809 MCU and ECC608 Crypto Chip

With the advance of IoT, security has become critical since devices are often connected to the Internet. There are several ways to improve security and one of them is to implement hardware security via crypto chips. One of those chips is Microchip ECC608 (aka ATECC608A) secure element which we previously found in Linux based hardware such as USB Armory MK-II USB Linux computer, and the official Arduino Nano 33 IoT Board. Seeed Studio has now introduced a new Arduino compatible board with Microchip ECC608 crypto chip: Seeeduino Crypto board powered by a Microchip ATmega4809 8-bit AVR MCU.

Testing NVIDIA Jetson Nano Developer Kit with and without Fan

A few weeks ago I received NVIDIA Jetson Nano for review together with 52Pi ICE Tower cooling fan which Seeed Studio included in the package, and yesterday I wrote a getting started guide showing how to setup the board, and play with inference samples leveraging the board’s AI capabilities. I’ll now test the board with the stock heatsink in both 5W and 10W modes, and see if thermal throttling does occur, and then I’ll fit the tower cooling fan to find out if we can extract more performance that way and how much lower the CPU temperature is. Jetson Nano Stress Tests with Stock Heatsink Let’s install SBC-Bench testing utility,

check it’s properly installed,

Black Friday & Cyber Monday 2019 – International Deals

As every year, November is the month of deals. With Single’s Day 2019 behind us, it’s time to look ahead for Black Friday and Cyber Monday. There will be plenty of deals in the US, but in this post, I’ll focus on international Black Friday 2019 deals available mostly from Chinese online shops like I did in previous years. Aliexpress Black Friday will start in about 10 days on Nov 29, 2019 ,12:00 AM PT and last until Dec 3, 2019 ,11:59 PM PT. But the site will start to show discounted prices on November 22, and you’ll be able to collect coins and coupons from that date, as well as add items to your cart before making the order during the 6-day promotion. Banggood Black Friday promotions have already started and will last until November 30 16:00 UTC+8. The easiest and most flexible way to get a discount is […]

Aliexpress Global Shopping Festival 2019

Singles’ Day, taking place on November 11 (11.11) every year, is the Chinese equivalent of Black Friday with shops in China offering deep discounts on their products. Popular Chinese online shopping websites catering to oversea markets also take advantage of the event to organize events and promotions for their customers. So just like I did in 2017 and 2018, I posted a list of Singles’ Day 2019 promotions in shops such as Banggood, GeekBuying, Aliexpress, GearBest, and others. Aliexpress Aliexpress Global Shopping Festival 2019 is already started in the sense you can browse products on the website, add them to your cart, and pay a lower price if you check out on November 11. Most shops will have discounts, but some of the most relevant to this site include Shenzhen Xunlong Software which will offer discounts of up to $8 for their Orange Pi Boards, Rak Wireless lowered the price […]

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 […]
