Testing NVIDIA Jetson Nano Developer Kit with and without Fan

Jetson Nano 52Pi-ICE Tower Cooling 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, and run it in 5W mode: The temperature never went over 44.5°C, and no throttling occurred. tegrastats during 7-zip multi-core test: Only two Cortex-A53 cores are used even under load, and power consumption is around 3.3 Watts. Let’s run sbc-bench in 10W mode: The maximum temperature …

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

SeeedStudio GD32 RISC-V kit with LCD

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 low-cost embedded development board. The board also includes an LCD …

Wio Lite RISC-V WiFi Board with ESP8266 Module Launches for $6.9

Wio Lite RISC-V

Released this summer, GigaDevice GD32V generated a lot of buzz, as a cheap general-purpose 32-bit RISC-V MCU, and soon after the $5 Longan Nano development board with LCD display and enclosure was launched to the market. However, many applications benefit or require some network connectivity with WiFi. Espressif Systems is a founding member of the RISC-V Foundation, so RISC-V WiSoCs (Wireless SoCs) are coming, but AFAIK none of those are available yet. In the meantime, Seeed Studio has launched Wio Lite RISC-V board which brings WiFi connectivity to GD32V MCU through an ESP8266 WiFi module. Wio Lite specifications: MCU – Gigadevice GD32VF103CBT6 RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM Wireless Module – ESP8266 WiFi Wio Core with 802.11b/g/n/ WiFi 4 connectivity Storage – MicroSD card slot USB – 1x USB Type-C port for power and programming Expansion – I/O headers for GD32 MCU, I/O header for Wio core ESP8266 module Debugging – Unpopulated 6-pin JTAG header …

NPi i.MX6ULL (Not So) Industrial-grade Linux SBC Starts at $39

NPi i.MX6ULL

[Update: I was initially informed the temperature range of the board was -40°C to +105°C, but Seeed Studio issues a correction explaining the Core module itself is rated -20℃ ~ 80℃ temperature range, and they haven’t tested the breakout board at all so we just don’t know. That’s mean the board is not industrial-grade at all. I’ve left the rest of the post mostly unchanged] We’ve covered several NXP i.MX boards in recent days, but here’s another NXP board courtesy of Seeed Studio with NPi i.MX6ULL industrial-grade Linux SBC powered by a low power NXP i.MX6ULL Arm Cortex A7 processor. The board also comes with 512MB RAM, either an 8GB eMMC flash or 256MB NAND flash for storage, features two Fast Ethernet ports, and various I/Os including two 40-pin GPIO expansion headers. NPi i.MX6ULL board specifications: Core Module SoC – NXP MCIMX6Y2CVM08AB single Cortex-A7 core @ up to 800 MHz System Memory – 512MB DDR3L Storage NPi-i.MX6ULL eMMC module – …
