M5Stack UnitV2 AI module gets USB camera and M12 camera versions

M5Stack UnitV2 is an ultra-compact Linux AI camera powered on Sigmastar SSD202D SoC with a dual-core Cortex-A7 processor @ 1.2 GHz, and 128MB on-chip DDR3 that was launched in April 2021 with a Full HD camera featuring a 68° field-of-view. M5Stack has now introduced two new models, one called M5Stack UnitV2 USB without any camera at all, instead relying on an external USB UVC camera, and the other named M5Stack UnitV2 M12 equipped with an M12 socket and shipping with both a normal focal length camera with an 85° FoV and wide-angle focal length with a 150° FoV. M5Stack UnitV2 USB M5Stack Unitv2 USB 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 – N/A Audio – Built-in microphone Connectivity – 2.4GHz WIFi 4 up to 150 Mbps (RTL8188FTV), […]

M5Stamp Pico ESP32-PICO-D4 module ships with a heat-resistant plastic shell

Most WiFi IoT modules are designed to be integrated into products with an enclosure, but the M5Stamp Pico module based on ESP32-PICO-D4 SiP comes with a removable heat-resistant plastic shell that protects the 3D antenna and components, while leaving space to solder headers and/or a Grove connector. The tiny module also comes with a button and RGB LED, and like other ESP32-based M5Stack hardware, M5Stamp Pico is programmable with UIFlow graphical programming platform and compatible with Arduino, MicroPython, and the ESP-IDF. M5Stamp Pico specifications: System-in-Package – Espressif Systems ESP32-PICO-D4 SiP with dual-core processor @ 240MHz, 520KB SRAM, 4MB flash, and 2.4 GHz Wi-Fi 4 up to 150 Mbps and Bluetooth 4.2 BR/LE connectivity Antenna – 2.4 GHz 3D antenna I/Os – 2.54mm pitch header with ADC, DAC, touch sensor, SD/SDIO/MMC host controller, SPI, SDIO/SPI slave controller, EMAC, PWM, UART, I2C, I2S, IR remote controller, up to 12x GPIO, pulse counter […]

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. […]
