In this article, will see how we can integrate the Beetle ESP32 C3 with home assistance.

Beetle ESP32 C3

The Beetle ESP32-C3 is based on the ESP32-C3, a RISC-V 32-bit single-core processor. Despite its tiny size (only 25×20.5 mm), it packs a punch with up to 13 IO ports broken out, making it ideal for various projects without worrying about running out of IO options.

Key Features:

Ultra-Small Size: The Beetle ESP32-C3 measures just 25×20.5 mm (0.98×0.81 inch), making it perfect for space-constrained projects.

Built-in Lithium Battery Charging Management:

  • Safely charge and discharge lithium-ion batteries directly on the board.
  • No need for additional modules, to ensure application size and safety.

Easy Screen Connectivity:

  • The matching bottom plate simplifies project assembly and screen usage.

Dual-Mode Communication:

  • Supports Wi-Fi and Bluetooth 5 (LE).
  • Reduces networking complexity.
  • Compatible with both Bluetooth Mesh and Espressif WiFi Mesh for stable communication and extended coverage.
