Enclosure for ESP8266 HW-364A with OLED Display and IR LED for Air Conditioner Controller (ESPHome)
Practical enclosure designed for the ESP8266 module on the HW-364A board (NodeMCU V3 with built-in 0.96" 128x64 OLED), featuring a dedicated space for an IR LED to enable air conditioner control via ESPHome.
🔧 Key Features and Uses:
- perfectly fits the ESP8266 HW-364A board (NodeMCU V3 with built-in 0.96" OLED)
- dedicated spot for the IR LED facing outward for optimal signal range
- easy access to USB port and programming pins
- requires use of a MOSFET transistor to drive the IR LED and a 10 kΩ resistor
🖨 Materials and Printing Recommendations:
- recommended materials: PLA, PETG for easy printing; ASA or ABS for durability and heat resistance
- layer height: 0.2 mm or lower for good print quality
- no infill needed – thin walls print as solid
- supports may be needed for OLED and IR LED mounts
⚠ Notes:
- enclosure designed specifically for the HW-364A (NodeMCU V3 with OLED) compatible with ESPHome
- IR LED must face outward without obstruction for proper function
- ESPHome code and wiring schematic for the transistor and resistor are available on GitHub (https://github.com/kurzejapatryk/esp8266-ac-controller)
