HT-CT62 ESP32C3 SX1262 BLE LoRa WiFi Module (863-928MHz) - 1/2/5pcs

HT-CT62 ESP32-C3 SX1262 LoRa Wireless Module

The HT-CT62 is a compact, highly integrated wireless communication module that combines the ESP32-C3 RISC-V microcontroller with the Semtech SX1262 LoRa transceiver. This module supports Wi-Fi, Bluetooth 5 (LE), and LoRa long-range communication. It is designed for low-power IoT applications that require multiple connectivity options in a single small-footprint device. It is tuned for the 863MHz to 928MHz frequency range, covering major global LoRaWAN regions including EU868 and US915.

Product Features

• Dual-Processor Architecture: ESP32-C3 RISC-V single-core processor (up to 160MHz) manages Wi-Fi/BLE, while the SX1262 handles LoRa communication.
• Triple Connectivity: Supports 2.4GHz Wi-Fi, Bluetooth 5 (LE), and LoRa Long Range protocols.
• High Sensitivity: SX1262 offers superior sensitivity (down to -148dBm) and improved power efficiency compared to older SX127x modules.
• Small Form Factor: Stamp-hole (castellated) design allows for easy SMT production or soldering onto carrier boards.
• Low Power Design: Deep sleep modes for both the ESP32-C3 and SX1262 make it suitable for battery-operated sensor nodes.
• Security: Hardware-accelerated encryption (AES-128/256, RSA, HMAC, and digital signatures).
