ESP32-based Waveshare DDSM Driver HAT (B) for Raspberry Pi supports DDSM400 hub motors

Waveshare DDSM Driver HAT (B) Raspberry Pi DDSM motor driver

Waveshare has recently launched DDSM Driver HAT (B), a compact Raspberry Pi DDSM (Direct Drive Servo Motor) motor driver designed specifically to drive the DDSM400 hub motors. This board is built around an ESP32 MCU and supports wired (USB and UART) and wireless (2.4GHz WiFi) communication. Additionally, the board features a physical toggle switch, which lets it choose between the ESP32 control or USB control modes. On ESP32 control mode you can control the device through a built-in web application. In the USB control mode, the motor driver can be controlled via USB from a host computer sending JSON commands. An XT60 connector is used to power the board, and programming is done through a USB-C port that connects to the ESP32. The board is suitable for robotics projects, especially for mobile robots in 6×6 or 4×4 configurations.

$12 Plant Bot is an ESP32-C3 soil sensor and pump driver for fully automated indoor plant care

Plant Bot ESP32-C3 Plant Monitor

The Plant Bot is an open-source, Internet-enabled plant monitor powered by the ESP32-C3 microcontroller and integrating a corrosion-resistant capacitive moisture soil sensor and a pump driver on a single printed circuit board, eliminating the need for additional cabling. The Plant Bot is designed to automate indoor plant care by combining moisture sensing, light sensing, and pump activation. It can be powered via USB or a single coin cell battery which lasts up to a week with daily updates. An onboard multi-color LED visually represents the current soil condition, ranging from red (dry) to blue (moist). The “Soil Level” line on the board indicates the maximum depth to which the sensor or device should be inserted into the soil. According to the maker, the Plant Bot will remain unaffected by corrosion if the soil level does not exceed this line. Other solutions we’ve covered with a soil sensor usually separate the […]
