Overview Flippezero Lite is a cost-optimized, open-source–compatible RF tool designed for makers and developers who mainly work with sub-GHz RF (315 / 433 MHz).

This version removes unused high-frequency RF and iButton hardware, focusing on core RF functionality, flexibility, and lower cost, while keeping compatibility with existing open-source firmware.

Main Features 315 MHz & 433 MHz RF transceiver External SMA antenna interface Compatible with open-source Flippezero firmware Supports NFC / RFID / Infrared / GPIO / U2F Bluetooth, LEDs, and power management tested

RF Range Reference Tested outdoors in an open area using a short 7 cm antenna: Receive range (315 / 433 MHz): ≥ 250 m Transmit range (433 MHz): ≥ 250 m Transmit range (315 MHz): ~120 m Actual performance depends on antenna selection and environment.

Power System Built-in 7.4 Wh lithium battery Standby current: ~3 mA (≈ 1 month standby time) Power-off current: ~25 µA

Known limitation: The GPIO 5 V output is always enabled and cannot be software-controlled. This does not impact power consumption or typical use.

Enclosure Custom 3D-printed enclosure Printed using PLA or PETG Lightweight but less heat-resistant than injection-molded cases Multiple color options available White version uses transparent PETG

Intended Use This device is intended for: RF learning and experimentation Prototyping and testing sub-GHz RF devices Makers and hardware developers
