The HT-CT62 is a versatile LoRa/LoRaWAN node module designed for long-range communication, low power consumption, high sensitivity, and cost-effectiveness. Featuring an ESP32-C3FN4 (a 32-bit microprocessor based on RISC-V architecture) and a Semtech LoRa Transceiver (SX1262), this module integrates 2.4 GHz Wi-Fi and LoRa two-mode wireless communication. The HT-CT62's small size and stamp hole package make it ideal for smart cities, smart farms, smart homes, Meshtastic applications, and general IoT projects. Supporting both LoRaWAN and custom LoRa implementations, it's a powerful tool for IoT makers.

Pin Map
FAQ
- My serial port does not print information: When using a USB to Serial tool, connect to serial port pins 20/21 of the device, or use pins 17/18 when connecting directly via USB.
- My LoRa signal became very bad after welding:The high temperature may cause the shielding shell of the device to shift, resulting in a short circuit.
- I can’t find the board in the board manager:Please select Wireless Mini Shell.
