You can choose the most suitable version based on your application needs.
The device integrates a wide array of features:
QWERTY keyboard
AI-enabled IMU (BHI260AP)
2.33" bar-type screen (resolution: 222 × 480)
Optional LoRa module (LR1121 or SX1262)
u-blox GPS module (MIA-M10Q)
RFID/NFC + RTC circuit
TI power management and monitoring chipset
ES8311 (microphone/speaker/headphone jack)
Rotary encoder with button
2 × 8 GPIO expansion header (designed for top-mounted NRF24L01 module)
¼-inch screw mount on the back
4 × M2 standoff mounts
Lanyard with LILYGO logo
The device comes preloaded with a UI demo firmware designed by LILYGO, enabling smooth interaction via the rotary encoder. This demo serves as a learning reference for developing customized applications across various usage scenarios.
