Mitsubishi Mini Split CN105 to Grove ESP32 Cable | JST PAP-05V-S to HY2.0-4P

Connect your Mitsubishi ductless mini split or central air unit to your smart home ecosystem with this fully assembled and tested CN105-to-Grove cable. Designed specifically for DIY smart home users, this cable bridges your HVAC system's internal service port with Grove-style microcontrollers (including Serin Controllers, M5Stack AtomS3 Lite or NanoC6) for direct integration into Home Assistant, Apple HomeKit, and ESPHome.

Length Options & Installation
- 20cm Cable: For wall-mounted mini splits. The compact length allows the cable and your controller to be tucked away completely within the empty space of the indoor unit's plastic housing.
- 50cm Cable: For larger ducted or central air units. Provides the necessary reach to mount the microcontroller outside the metal chassis, preventing Wi-Fi signal interference.
- See product photos for installation examples of both configurations.

Features
- Durability: Finished in orange PET braided sleeving and heat shrink for maximum abrasion resistance.
- Quality Control: Every cable's power and communication wires are physically tested prior to shipping.

Compatibility & Open-Source Integration
This cable interfaces directly with the internal CN105 5-pin header, which comes standard on most Mitsubishi Electric HVAC models. It's designed for Serin Labs controllers and open-source ESP32-based heat pump projects, including:
- MitsubishiCN105ESPHome
- mitsubishi2MQTT
- mUART
- mitsubishi_cn105 ESPHome component
- SwiCago library
