NVIDIA Jetson Nano/Xavier NX carrier board offers 5 SATA, 6 CSI camera, dual GbE, and more
Leetop has introduced two carrier boards for NVIDIA Jetson Nano or Xavier NX modules, with Leetop A205 a full-featured carrier board offering five SATA ports, six MIPI CSI camera interfaces, an M.2 Key E slot, dual Gigabit Ethernet, four USB 3.0 ports, dual HDMI output and more, as well as the more compact Leetop A203 about the size of the modules themselves and offering Gigabit Ethernet, HDMI output, USB 3.0/2.0 ports, a camera interface, and an M.2 slot for optional WiFi and Bluetooth connectivity. We’ll focus on the former in this article, as it offers more features, and the smaller board provides less functionality than the NVIDIA Jetson Nano developer kit at a much higher price, although I understand it can still be useful for space-constrained applications. Leetop A205 specifications: Supported SoMs – NVIDIA Jetson Nano and Jetson Xavier NX Module Compatibility Storage – 5x SATA ports, MicroSD card slot […]
Zidoo M6 Arm mini PC review – Part 1: Unboxing and Teardown
I’ve just received my first Rockchip RK3566 platform with Zidoo M6 Arm mini PC that supports Ubuntu 18.04, Android 11, and Station OS. I was sent the standard version with 4GB RAM and 32GB eMMC flash that will be suitable for most applications. I’ll start Zidoo M6 review with an unboxing and a teardown to check the hardware design and “hidden” features before reviewing with the device with Android 11 and/or Ubuntu 18.04. Zidoo M6 Unboxing There’s nothing special about the package (and that’s a good thing in order to go more easily through customs), so let’s check out the package content. Beside the box, it’s there’s an HDMI cable, a 5V/2A power adapter with a removable US plug, an IR remote control, and a user manual. The remote control comes with an IR learning function to record some of your TV keys like volume, power, and source selection without […]

Gateworks GW16146 is an 802.11ah WiFi HaLow Mini PCIe module
Gateworks GW16146 is an 802.11ah WiFi HaLow Mini PCIe card designed to provide long-range wireless to IoT applications utilizing the company’s Venice and Newport single board computers. We first noticed 802.11ah WiFI LPWAN standard operating at 900 MHz for the Internet of Things in 2014, followed by Newracom NRC6101 chip in 2015, and the following year the Wi-Fi Alliance decided to call the new standard “Wi-Fi HaLow“. I was expecting it to compete with the likes of LoRa and NB-IoT, but I have not heard much about it, and when I asked a WiFi module and board supplier earlier this year, they seemed surprised I would even be interested in this type of hardware and, obviously, did not have any… So it’s good to see some new hardware coming out. Gateworks GW16146 specifications: 802.11ah Halow connectivity Silex SX-NEWAH 802.11ah Module based on Newracom NRC7292 System-on-Chip (US only) Compliant with IEEE […]
