Description

The HT-CT62 module from Heltec Automation Automation combines Espressif’s ESP32-C3FN4—a 32-bit RISC-V processor running at up to 160 MHz—with Semtech’s SX1262 LoRa transceiver. This architecture provides a robust foundation for IoT edge nodes requiring both local network connectivity via 2.4 GHz Wi-Fi/Bluetooth 5.1 and long-range, low-data-rate communication via LoRa/LoRaWAN. The module’s integrated 4MB SiP flash and ample SRAM support complex application logic and Over-The-Air (OTA) updates.

Engineered for extreme power efficiency, the CT62 achieves a deep sleep current of just 10µA, enabling multi-year operation on coin-cell or small LiPo batteries. Its impedance-matched RF front-end and dual IPEX antenna connectors (one for 2.4GHz, one for LoRa) ensure optimal signal integrity and range. The compact, surface-mount form factor is designed for automated assembly, making it suitable for scalable smart city, agricultural telemetry, and industrial monitoring solutions.

Key Features

  • Dual-core wireless SoC: ESP32-C3FN4 (160 MHz RISC-V) with integrated Wi-Fi 802.11 b/g/n and Bluetooth 5.1.
  • Long-range LoRa transceiver: Semtech SX1262 supporting LoRaWAN 1.0.2 on 433-510MHz frequency bands.
  • Ultra-low-power design: Deep sleep mode consumes only 10µA, with configurable power management for battery life optimization.
  • Compact SMT footprint: 17.78 x 17.78mm board with 1.27mm stamp-hole pins for high-density PCB integration.
  • Enhanced memory: 4MB SiP flash, 400KB SRAM, and 384KB ROM for application code and data buffers.
  • Dedicated antenna ports: Separate IPEX 1.0 connectors for 2.4GHz and LoRa antennas with optimized impedance matching.
  • Broad development support: Fully compatible with Arduino framework, ESP-IDF, and third-party LoRaWAN stacks.
  • Industrial temperature rating: Operates reliably from -40°C to +85°C for harsh outdoor and industrial environments.

Applications

  • Smart agriculture sensors for soil moisture, temperature, and livestock tracking over long distances.
  • Industrial IoT (IIoT) telemetry for remote monitoring of equipment status, tank levels, and environmental conditions.
  • Smart city infrastructure such as smart parking, waste management, and streetlight control networks.
  • Asset and logistics tracking using combined LoRaWAN for location and Wi-Fi for local data offloading.
  • Home automation and security systems requiring both local control (Wi-Fi/BLE) and long-range alerts (LoRa).

Frequently Asked Questions

How do I program the Heltec Automation CT62 module?

The CT62 is fully compatible with the Arduino IDE. Install the ESP32 board support via the Boards Manager, then select 'Heltec Automation Wireless Stick Lite (C3)' or a similar ESP32-C3 target. You can use popular LoRa libraries like 'RadioLib' or 'LoRa' to control the SX1262 transceiver. For advanced features, you can also develop using the official ESP-IDF framework with Espressif's LoRa component. The module's stamp holes provide access to all necessary GPIOs for UART, SPI, and I2C communication with external sensors.

What antenna should I use with the CT62's IPEX connectors?

The module has two separate IPEX 1.0 (U.FL) connectors: one for the 2.4GHz Wi-Fi/Bluetooth radio and one for the sub-GHz LoRa radio. For LoRa, use a monopole or dipole antenna tuned to your operating frequency (e.g., 433MHz or 510MHz) with a 50-ohm impedance. For the 2.4GHz antenna, a standard Wi-Fi/Bluetooth antenna with IPEX connector is suitable. Ensure both antennas are properly seated, as the RF performance and range depend heavily on correct antenna matching and placement.

What is the power supply requirement for the CT62 module?

The CT62 module requires a stable 3.3V DC power supply, typically within a 3.0V to 3.6V range. It can be powered via the VCC and GND pins on its stamp-hole footprint. For battery operation, a regulated 3.3V output from a LiPo battery with a protection circuit or a 3V coin cell (CR2032) is recommended. Pay close attention to the deep sleep current of 10µA; ensure your power regulator or supply does not have a higher quiescent current that would negate the module's low-power benefits.

How do I configure the CT62 for LoRaWAN operation?

To use the CT62 with LoRaWAN, you need to flash a compatible stack like LoRaMac-node or use the Arduino LMIC library. Configure the regional parameters (EU868, AS923, etc.) to match your 433-510MHz frequency plan. You must obtain DevEUI, AppEUI, and AppKey from your LoRaWAN network server (like The Things Network or ChirpStack). Use the SPI interface to communicate with the SX1262 chip, setting the correct spreading factor, bandwidth, and coding rate. The module supports OTAA (Over-the-Air Activation) and ABP (Activation by Personalization) join modes.
