HELTEC Automation Wireless stick

In order to meet the user’s requirements for high performance and small size, we designed this product. On the basis of WiFi LoRa 32, it’s has a smaller size, 0.49″ OLED display, and better RF characteristics.

Features:

1. Microprocessor: ESP32-S3FN8 (Xtensa® 32-bit LX7 dual core processor, five stage pipeline rack Structure, main frequency up to 240 MHz).

2. SX1262 LoRa node chip.

3. Type-C USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures.

4. Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching).

5. Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz metal spring antenna, reserved IPEX (U.FL) interface for LoRa use.

6. Onboard 0.49-inch 64*32 dot matrix OLED display, which can be used to display debugging information, battery power, and other information.

7. Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing.

8. Support the Arduino development environment.

9. We provide ESP32 + LoRaWAN protocol Arduino® library, this is a standard LoRaWAN protocol that can communicate with any LoRa gateway running the LoRaWAN protocol. In order to make this code running, a unique license is needed.

10. With good RF circuit design and low-power design.
