MyCobot robotic arm is offered with Raspberry Pi 4 or M5Stack ESP32 modules

Elephant Robotics’ MyCobot robotic arm was introduced last year with M5Stack Atom & Basic ESP32 modules with 6-degrees of freedom, a 250 grams max payload, available now for $599. The company has launched a new $699 version – MyCobot-Pi – with most of the same features, except for an upgrade to Raspberry Pi 4B which offers more performance and flexibility. Both versions of MyCobot arm robotic arm support accessories such as a gripper and a suction pump attachable through a LEGO connector, but while the original version – MyCobot-M5 – relies on Arduino programming, the new MyCobot-Pi runs Debian/Ubuntu and ROS operating systems with image recognition algorithms that can work with a variety of cameras. Since we’ve missed last year’s announcement, we’ll cover both models in this article. MyCobot Robotic Arm Despite the mechanical parts being the same, the specifications for MyCobot-M5 and MyCobot-Pi differ quite a lot: Controller MyCobot-M5 […]

M5Stack UnitV2 Linux AI camera features Sigmastar SSD202D SoC

We’ve written about SigmaStar SSD201/SSD202 processors several times now. The low-cost dual-core Cortex-A7 processor comes with 64MB or 128MB built-in RAM, and so far has been found in modules, smart displays, an SBC, and a gateway only available from China via stores like Taobao. But with mainline Linux support progressing nicely, it was only a matter of time until others make a product based on the processor, and M5Stack Unitv2 is an “AI” camera combining SSD202D processor with 128MB DDR3, and a GC2145 2MP camera sensor. M5Stack UnitV2 specifications: SoC – SigmaStar SSD202D dual-core Cortex-A7 processor @ 1.2 GHz with 128MB on-chip DDR3 Storage – 512MB on-chip NAND flash with around 100MB free space, MicroSD card socket Camera GC2145 1080p color sensor with USB UVC support 68° FoV, 60 cm to ∞ depth of field (DoF) Audio – Built-in microphone Connectivity – 2.4GHz WIFi 4 up to 150 Mbps USB […]

Giveaway Week – M5Stack Atom Echo ESP32 Speaker

I reviewed M5Stack Atom Echo Bluetooth speaker powered by ESP32 earlier this year, and that will be the fifth prize of Giveaway Week 2020. It’s very much like a (low-quality) Bluetooth speaker, but you can program it with the Arduino IDE to do whatever you want. There’s also a Grove connector and I/O headers to control external modules. There’s no battery, so a USB-C cable is needed for power. To enter the draw simply leave a comment with your country and whatever else you’d like to say. If the country is missing, I’ll consider the entry void. Other rules are as follows: Only one entry per contest. I will filter out entries with the same IP and/or email address. Contests are open for 48 hours starting at 11 am (Bangkok time) every day. Comments will be closed after 48 hours. If comments are open, the contest is still going on. […]

M5StickC PLUS ESP32-PICO Devkit Comes with 1.14-inch LCD, 120 mAh Battery and Buzzer

M5StickC PLUS ESP32-PICO DevKit Bluetooth and WiFi

Shortly after introducing the Core2 ESP32 IoT Development Kit with a 2-inch touch display, 390 mAh battery earlier this week, M5Stack has announced the availability of another ESP32 WiFi & Bluetooth IoT devkit, with the more compact M5StickC PLUS featuring a 1.14-inch display, a 120mAh battery, motion, sensor, a buzzer and the usual Grove connector for expansion. M5StickC PLUS is an upgrade to the original M5StickC that lacks the buzzer and features a smaller 0.96-inch display and a lower capacity 96 mAh battery. The new model can be purchased now for $13.95 plus shipping on Aliexpress, while the original device, that happens to be M5Stack top-selling product, is still available for $9.95. M5StickC PLUS key features and specifications: SiP – Espressif Systems ESP32-PICO-D4 system-in-package with ESP32 dual-core WiFI and Bluetooth IoT processor @ up to 240 MHz, 4MB SPI flash Display – 1.14-inch Color TFT LCD with 135×240 resolution (ST7789v2 […]

M5Stack ATOM is a Compact, Fully Integrated ESP32 Development Kit

When working on a project you may need an MCU or MCU board, an external display, a breadboard, and other accessories like sensors and jumper cables. It does the job, but it can be messy. Recently, we wrote about M5Stack M5StickV AI camera, but the company is better known for its ESP32 IoT development kits enabling neater project thanks to hardware that integrates MCU, I/O headers, display, and sensors into an enclosure. Their latest offerings are ATOM series toolkits that come in two versions: ATOM Lite and ATOM Matrix. Let’s have a look at both. M5Stack ATOM Lite Specifications: SiP – ESP32-PICO-D4 system-in-package with ESP32 dual-core processor with WiFi 4 and Bluetooth 5.0/5.1 Storage – 4 MB flash Crystal oscillator and passive components USB – 1x USB Type-C port Expansion 9-pin header with 6 GPIOs compatible with jumper cables 4-pin PH2.0 connector with 2x GPIO, 5V and GND Misc – […]
