Hackerboards.com single board computer database has been around for several years starting as Board-DB, but I noticed another one called FindBoard while browsing on Aliexpress with some more exotic boards. Hackerboards’ database currently features 467 SBCs and MCU boards, while FindBoard has 453 boards. There are some overlaps, but also boards that are not found in the first database. Many of the boards on FindBoard are Linux-capable, but they are also some microcontroller boards as we can see from the screenshot above. If Chinese is selected, the “Buy now” will redirect you to Taobao, and if it is English they will be a link to an Aliexpress page. There’s a parametric search function for FinderBoard single board computer database but it’s really only useful when selecting one single parameter because the system use “OR” instead of “AND”. So if select 01Studio and Linux as above, it will show results for […]
ultraArm P340 Arduino-based robotic arm draws, engraves, and grabs
Elephant Robotics ultraArm P340 is a robot arm with an Arduino-compatible ATMega2560 control board with a 340mm working radius whose arm can be attached with different accessories for drawing, laser engraving, and grabbing objects. We’ve previously written and reviewed the myCobot 280 Pi robotic arm with a built-in Raspberry Pi 4 SBC, but the lower-cost ultraArm P340 works a little differently since it only contains the electronics for controlling the servos and attachments, and needs to be connected to a host computer running Windows or a Raspberry Pi over USB. ultraArm P340 specifications: Control board based on Microchip ATMega2560 8-bit AVR microcontroller @ 16MHz with 256KB flash, 4Kb EEPROM, 8KB SRAM DOF – 3 to 4 axis depending on accessories Working radius – 340mm Positioning Accuracy – ±0.1 mm Payload – Up to 650 grams High-performance stepper motor Maximum speed – 100mm/s Communication interfaces – RS485 and USB serial Attachment […]

Aetina unveils NVIDIA Jetson Orin Nano and Orin NX edge embedded systems
Aetina has recently announced several embedded systems based on NVIDIA Jetson Orin NX and Orin Nano which they showcased at CES 2023. We’ll specifically have a look at the AIE-KO21/31 and AIE-KN31/41 edge devices designed for mainstream and entry-level edge AI computing. NVIDIA introduced the NVIDIA Jetson Orin NX SO-DIMM modules in March 2022 and followed up with the lower-cost pin-compatible Jetson Orin Nano modules in September with mass production scheduled for Q4 2022 and Q1 2023 respectively. Last week, we covered the first NVIDIA Jetson Orin NX edge AI computer we had seen, namely Seeed Studio reComputer J4012, but it turns out Aetina also announced their own Jetson Orin NX/Orin Nano industrial embedded computers around the same time. Aetina AIE-KO21, AIE-KO31, AIE-KN31, and AIE-KN41 specifications: System-on-module AIE-KO21 – NVIDIA Jetson Orin Nano 4GB with up to 20 TOPS of AI performance AIE-KO31 – NVIDIA Jetson Orin Nano 8GB with […]
TwoTrees TS2 laser engraver review – Part 2: A beginner’s experience with LaserGRBL and MKSLaser
I’ve now had time to play with TwoTrees TS2 laser engraver after doing an unboxing and providing assembly instructions last month, so I can report my experience in this review using LaserGRBL program and MKSLaser mobile app. Note that this is my first laser engraver, and I’ll detail the many issues and mistakes I’ve come across so it might be useful to other beginners. Testing TS2 laser engraver assembly Before doing some engravings and cuts, we’ll have to test the TS2 to make sure it was properly assembled and we can operate it normally. The company is recommending the open-source and free LaserGRBL or the paid Lightburn program to control the TS2. I went with the former which happens to only work in Windows or macOS, while most of my hardware is running Linux or Android. So I dug out an older HDMI PC stick, the MeLE PCG01 running Windows […]
$4 Sipeed M0S Dock IoT development board features BL616 WiFi 6, BLE 5.2, and Zigbee RISC-V microcontroller
As expected, Sipeed has now launched the Sipeed M0S IoT module based on Bouffalo Lab BL616 RISC-V microcontroller with 2.4 GHz WiFi 6, BLE 5.2, and Zigbee connectivity along with the “Sipeed M0S Dock” development board. The M0S is a tiny module (11×10 mm) with a 320 MHz wireless MCU, a ceramic antenna, and castellated holes for I/Os, and the Sipeed M0S Dock places the module on an easy-to-use board with a USB Type-C port, a BOOT button, and a 12-pin 2.54mm pitch header.

Making a DIY Raspberry Pi camera mount with privacy mode!
I’ve just repurposed an empty XYLITOL gum bottle into a DIY camera mount for the Raspberry Pi Camera Module 3 with privacy mode to boot… In order to avoid confusion, while Xylitol is a chemical compound, it’s also a Japanese brand of chewing gums (Lotte XYLITOL) that is sold in Thailand and other countries. I’m specifically talking about the latter in this post. Raspberry Pi Trading has just sent me a bunch of Raspberry Pi Camera Modules 3 for review, and since I don’t have any camera mount I initially thought maybe I’ll laser cut some mount or use some LEGOs as I did with the e-CAM20_CURB camera for Raspberry Pi 4. But then I saw some empty XYLITOL gum bottles, noticed the cap would open vertically, and it seemed like the modules might fit in there as well. And indeed they do with the Raspberry Pi camera modules snugged […]
