| DB4238B5-BD is a dual-frequency (L1 + L5) single-beidou positioning module integrated with a ceramic antenna. It features extremely high sensitivity, ultra-low power consumption, and a compact design. It supports the single-band, single-system cm4f (main frequency 350 MHz, 22nm technology) chip of the third-generation Beidou Navigation Satellite System (BDS-3), and is capable of tracking (L1 & L5) frequency bands of civilian navigation systems (B1I, B1C, B2A). This module receives signals through the antenna and obtains complete serial data such as position, speed, and time information via NMEA protocol or custom serial port protocol. The ultra-high tracking sensitivity of -165 dBm has broken through the positioning bottleneck that was impossible to achieve in previous products, enabling the positioning range to cover complex environments such as between city buildings and areas with dense forests. Its compact size and ultra-low power consumption make it easy to integrate into small portable or equipment with volume requirements. |
