4. Návod k obsluze

4.1. Zapnutí

Connect the board to a power source via the Type-C USB port or rely on the installed 1100mAh battery. The board features automatic switching between USB and battery power.

4.2. Vývojové prostředí

The ESP32 LoRa V3 Development Board supports the Arduino development environment. Use the integrated CP2102 USB-to-serial chip for programming and debugging. Ensure the necessary drivers are installed on your computer for proper recognition of the device.

For Meshtastic applications, refer to the official Meshtastic documentation for firmware flashing and configuration.

4.3. Konektivita

• Wi-Fi: The board supports 802.11ax and 802.11n standards.
• LoRa: Utilizes the SX1262 LoRa chip for long-range communication. Ensure the 915MHz antenna is properly connected.
• Bluetooth: Supports both Classic Bluetooth and BLE (Bluetooth Low Energy).

4.4. OLED displej

The 0.96-inch 128x64 dot matrix OLED display can be used to show debugging information, battery levels, and other relevant data from your application.

5. Údržba

5.1. Péče o baterie

The 1100mAh Lithium Polymer battery has an integrated management system for charge, discharge, and overcharge protection. To prolong battery life:

• Vyhněte se častému úplnému vybíjení baterie.
• Pokud zařízení delší dobu nepoužíváte, skladujte jej na chladném a suchém místě.
• Charge the battery using a standard USB power adapter.

5.2. Case Cleaning

Clean the N30 protective case with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the plastic or screen protector.

5.3. Aktualizace firmwaru

Regularly check for firmware updates from the official MakerHawk or relevant project (e.g., Meshtastic) websites to ensure optimal performance and access to new features.

6. Řešení problémů

• Zařízení nebylo počítačem rozpoznáno: Ensure the CP2102 USB-to-serial driver is installed. Search online for "CP2102 driver" and install the appropriate version for your operating system.
• Failed to flash firmware: Verify the correct drivers are installed. Ensure the board is in bootloader mode (often by holding a "BOOT" button while connecting USB or resetting). Check your development environment settings.
• Poor Bluetooth/LoRa range: Ensure antennas are securely connected. For Bluetooth, the onboard metal spring antenna is used. For LoRa, the external antenna must be connected to the U.FL port. Environmental factors can also affect range.
• OLED displej nefunguje: Check connections to the board. Ensure your code initializes and writes to the OLED correctly.
• Baterie se nenabíjí: Verify the USB-C cable and power adapter are functional. Check the battery connection to the board. The board has overcharge protection.
