### V3.1 differences
|
|
|
|
Firmware remains the same as V3 below. Compare schematics: [V3.0](<https://web.archive.org/web/20221127054612/https://resource.heltec.cn/download/WiFi_LoRa32_V3/HTIT-WB32LA(F)_V3_Schematic_Diagram.pdf>) and [V3.1](<https://resource.heltec.cn/download/WiFi_LoRa_32_V3/HTIT-WB32LA(F)_V3.1_Schematic_Diagram.pdf>). Key differences:
|
|
|
|
- Removal of [FDG6322C](https://www.mouser.com/datasheet/2/308/1/FDG6322C_D-2312203.pdf) (a dual N & P channel FET) from the V3.1 power supply.
|
|
- Antenna filter values in V3.1 (L11 = 1.8pF, C15 = 2.7nH, C24 = 1.8pF) align more closely with ESP32-S3 reference design than V3.0 (L11 = 1.6nH, C15 = 6.9pF, C24 = 2.4pF).

### Flashing
|
|
|
|
To flash ESP32-S3 devices like the Wireless Tracker, you typically need to place them in Espressif's firmware download mode. Use the "1200bps reset" button in the web flasher to do this. If this method does not work for any reason, you can follow the manual process below.
|
|
|
|
:::warning
|
|
|
|
Do not proceed unless an antenna is connected to avoid possible damage to the device's radio.
|
|
|
|
:::
|
|
|
|
The following process will manually place the device into the Espressif Firmware Download mode:
|
|
|
|
1. Unplug the device.
|
|
2. Press and hold the USER button.
|
|
3. Plug device in.
|
|
4. After 2-3 seconds, release the USER button.
|
|
|
|
With the device now in the Espressif Firmware Download mode, you can proceed with flashing using one of the supported flashing methods. It's generally recommended to use the [Web Flasher](https://flasher.meshtastic.org/). You can select "Heltec Wireless Tracker" from the device drop-down.
