$20 ATOMIC Display Base is a low-cost HDMI display driver for M5Stack’s ESP32-based Atom IoT controllers

M5Stack ATOMIC Display Base (GW1NR)

M5Stack has recently launched the M5Stack ATOMIC Display Base, an HDMI display driver designed to emulate traditional SPI TFT-LCD data output using Gowin GW1NR-9C FPGA and a built-in LT8618SX RGB-to-HDMI chip and designed to work with the company’s Atom IoT controller family based on ESP32 wireless microcontrollers. The module supports up to 720p (1280×720) image output with a 24-bit color depth and has an average frame rate of 12–16 FPS. Additionally, it can be paired with ATOM series hosts for various memory and application needs. These features make this compact device suitable for industrial control displays, smart home information screens, educational and conference presentations, and remote monitoring displays. The only downside of this device is that it requires a display with adaptive resolution scaling to avoid compatibility issues.

Waveshare RoArm-M2 ESP32 robotic arms offer four degrees of freedom, various servo options

RoArm M2 Series Robotic Arm

Waveshare has recently launched the RoArm-M2-S and RoArm-M2-Pro ESP32 robotic arms with four degrees of freedom, or 4-DOF for short. The main difference is that the RoArm-M2-S is equipped with standard servos, while the RoArm-M2-Pro features all-metal ST3235 bus servos, adding more durability and performance. Designed for educational and robotics applications, the 4-DOF RoArm-M2 is sturdy yet lightweight, built using carbon fiber and aluminum alloy. It can handle payloads up to 0.5kg and has a workspace diameter of 1 meter. The arm offers high precision with a 12-bit magnetic encoder and dual-drive technology for improved torque and stability. On top of that, it features a 12-bit magnetic encoder and dual-drive technology for improved torque and stability. Other features include a 360° omnidirectional base and support for both wireless (WiFi, ESP-NOW) and wired (USB) control. These features make this device suitable for various applications including industrial automation, education, research, and DIY robotics projects. Waveshare […]
