GNSS Standalone
Firefly X1 - Ultra-Compact, Ultra-Powerful
Firefly X1 is one of the smallest MT3333-based module in the world, offering unrivaled positioning performance and features in an ultra-compact size of just 9.0 x 9.5 mm.
Despite the smaller size, Firefly X1 incorporates the complete set of high-quality components such as an additional-LNA, SAW-Filter, TCXO, RTC Crystal and SMPS; all of which enable high positioning accuracy but with a lower power consumption.
Firefly X1 is the only MediaTek based GNSS module offering I2C and SPI interfaces. Firefly X1 supports SBAS, Anti-Jamming, AlwaysLocateTM, EASYTM, EPOTM, and logger function, and these features can be further extended with our free customization service.
