Higher power usage than nRF52, but often cheaper and supports Wi-Fi if desired.-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.
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:
- Unplug the device.
- Press and hold the USER button.
- Plug device in.
- 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. You can select "Heltec Wireless Tracker" from the device drop-down.

- Connectors:
- USBUSB (Universal Serial Bus). The wired connection used to power a device, flash firmware onto it, and communicate with it over serial.-C
- Antenna:
- U.FLIPEXA miniature coaxial antenna connector found on many boards. The docs write it as U.FL/IPEX, using the two names interchangeably./IPEXIPEXA miniature coaxial antenna connector found on many boards. The docs write it as U.FL/IPEX, using the two names interchangeably. antenna connector for LoRaLoRaA low-power, long-range wireless communication technology used by Meshtastic devices to enable communication over distances of several kilometers without the need for cellular, Wi-Fi, or other traditional network infrastructures.
- Integrated 2.4 GHz PCB antenna

Wireless Paper V1.1
The Wireless Paper V1.1 is listed as "Wireless Paper" in the firmware files and on the web flasher.
This device may have issues charging a connected battery if utilizing a USBUSB (Universal Serial Bus). The wired connection used to power a device, flash firmware onto it, and communicate with it over serial.-C to USBUSB (Universal Serial Bus). The wired connection used to power a device, flash firmware onto it, and communicate with it over serial.-C cable. It's recommended to use a USBUSB (Universal Serial Bus). The wired connection used to power a device, flash firmware onto it, and communicate with it over serial.-A to USBUSB (Universal Serial Bus). The wired connection used to power a device, flash firmware onto it, and communicate with it over serial.-C cable.
- MCUMCU (Microcontroller Unit). The microcontroller that runs the firmware on a device. The hardware tables list the MCU for each supported board.:
- ESP32ESP32A chipset of microcontroller made/designed by Espressif, used by a number of devices. Higher power usage than nRF52, but often cheaper and supports Wi-Fi if desired.-S3FN8 (WiFi & Bluetooth)
