Description ▼
Note: This is the Heltec RD01 Sensor Extension Kit for RadioCore RC32 at 902–928 MHz, TX 21±1 dBm. It includes the RC32-62 RadioCore module, LoRa antenna, 18650 Li-ion battery, and a PLA 3D-printed enclosure with the RD01 carrier board.
RD01 is a sensor-focused expansion enclosure for RC32. It integrates an 18650 battery holder, three B2B sensor interfaces for compatible Heltec sensor modules, and three externally accessible HY2.0 4-pin I2C-style connectors — useful for Home Assistant and other sensor projects without opening the case.
KEY FEATURES
- Includes RC32 (ESP32-S3 + SX1262) — 902–928 MHz, TX 21±1 dBm.
- PLA 3D-printed enclosure with detachable protective covers.
- Six sensor interfaces: 3× B2B (compatible sensor modules) + 3× HY2.0 4-pin connectors accessible from outside the case.
- Onboard 18650 Li-ion battery holder; battery included with this kit.
- Whip LoRa antenna (SMA female); USB-C; USER / RST / POWER controls.
- Designed for sensor integration (e.g. Home Assistant). RC32 can run Meshtastic / MeshCore, but Heltec notes pin conflicts if sensors are connected — not recommended when using the sensor ports.
