HELTEC HT-CT62 ESP32C3 SX1262 LoRa Node Meshtastic LoRaWAN 868MhzOpenELAB Technology Ltd.

Description

HT-CT62 is a LoRa/LoRaWAN node module with a long communication range, low power consumption, high sensitivity, and low cost. The module is composed of ESP32-C3FN4 (32-bit microprocessor based on RISC-V architecture) and Semtech LoRa Transceivers (SX1262). The module integrates 2.4 GHz Wi-Fi and LoRa two-mode wireless communication. HT-CT62 is a small volume, stamp hole package module, it’s the best choice for smart cities, smart farms, smart homes, and IoT makers.

FAQ

1

My serial port does not print informatio.

When you use the USB to Serial tool, you need to connect the serial port pins 20/21 of the device, and 17/18 when you connect directly via USB.

2

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.

3

I can’t find the board in the board manager.

Please select Wireless Mini Shell.
