In this captivating video, Voltlog unveils the latest iteration of their revolutionary ESP32-based Valve Actuator project – Revision D. Designed to streamline manufacturing and offer improved functionality, this enhanced version is a testament to the project’s ongoing evolution. Originally conceived as an open-source solution for controlling underfloor heating systems, the Valve Actuator project has gained a loyal following due to its compatibility with popular platforms like Tasmota, ESPHome, and Home Assistant.
With over a couple of hundred units already in operation, the RevD promises to further elevate the user experience and simplify assembly. One of the most notable updates in this revision is the ability to power the valves with a separate AC voltage, such as 24V AC. This feature caters to users with pre-existing underfloor heating systems, providing greater flexibility and compatibility.
Additionally, Voltlog has optimized the PCB design by transitioning from through-hole components to surface-mount technology (SMT) wherever possible, improving manufacturability and reducing potential errors during assembly. The RevD also introduces an innovative LED control feature, allowing users to turn the output status LEDs on or off via GPIO16.
This not only conserves power but also enhances the device’s versatility, making it suitable for discreet installations where visible LEDs are undesirable. Voltlog’s commitment to quality is evident in their collaboration with PCBWay.com, the official provider of printed circuit boards for the channel.
The limited-edition first batch of RevD boards boasts a stunning red solder mask with gold-plated ENIG finish, showcasing exceptional craftsmanship and attention to detail.
