Description ▼
Note: This is the Heltec Wireless Stick Lite (V3) for the US band (902–928 MHz). MCU ESP32-S3FN8 + LoRa SX1262. Compatible with Meshtastic, MeshCore, and LoRaWAN.
HTIT-WSL is Heltec’s Wi-Fi / Bluetooth / LoRa development board for users who do not need the OLED found on WiFi LoRa 32. Compact “Lite” form factor with ESP32-S3 + SX1262 (V3). The older V2 used ESP32-D0 + SX1276 and Micro USB.
KEY FEATURES
- Microprocessor: ESP32-S3FN8 (Xtensa® 32-bit LX7 dual-core, up to 240 MHz).
- LoRa node chip: SX1262.
- Type-C USB with voltage regulation, ESD / short-circuit protection, and RF shielding measures; integrated CP2102 USB-UART.
- SH1.25-2 battery interface with lithium charge/discharge management, overcharge protection, battery voltage detection, and USB/battery auto-switching.
- Wi-Fi + LoRa + Bluetooth; onboard 2.4 GHz metal spring antenna for Wi-Fi/BT; LoRa via reserved IPEX (U.FL).
- No onboard OLED — compact “Lite” form factor vs WiFi LoRa 32.
- Arduino-compatible via Heltec ESP32 framework / libraries; used with Meshtastic and MeshCore.
- Low-power design with deep-sleep current under 10 µA.

- 1 × LoRa Antenna
- 1 × SH1.25×2 Battery Connector
- 1 × Pin Map Sticker
NOTES
- V3 is not drop-in identical to V2 libraries — SX1262 needs libraries that support it (e.g. Heltec LoRaWan_APP vs older SX127x-only libs).
- Battery is not included — use a compatible 3.7V Li-Ion / Li-Po with an SH1.25×2 connector.
- Docs: product page, wiki (Wireless Stick Lite V3), datasheet HTIT-WSL_V3 Rev 1.1.
