Description
Floor heating controller for proportional actuator
All informations on https://github.com/nliaudat/esp32_8ch_motor_shield
- Make a floor heating controller
- ESP motor shield (done in v58 rev 1.49 )
- Can control 8 DC motors or 4 steppers motor
- Can drive 8 Homematic valve actuators [HmIP-VDMOT] (~15$ each)
- The card use a ESP32-WROOM-32D as logics and wifi connection. (You can get a 32U if you want an external antenna).
- It now supports the ESP32-C3 supermini
- The software runs under esphome to be easy to customize and linked with https://www.home-assistant.io
- Can be extended up to 16 channels (I recommend to get 2 boards for better performances, but the shifts registers can be extended up to 4 shiftregOut)
- Use BEMF (back electromotive force) from motors to get endstops
- Can be directly linked to external temperature sensors (wifi,BLE, or via available free pins)
- 2 onewire connectors (to have precise IN/OUT temperature control over heating circuit)
- USB-C power input
- Easily hackable
- PCB can be ordered with chips assembled at JLPCB for 13$$/unit. (:warning: For old AC version, you have to isolate the AC part with tape)
- The 3.3v power (or 5v) can be HKL-5MX or HKL-PMX (under 2.75$) . The new version use DC input only with usb-c
- ESP32-WROOM-32D devkit with 38 pin costs approx 3.8$ . The ESP32-C3 supermini approx 2.5$
- Box is 3D printed
