7-10Km 250mW FHSS Wireless Transceiver RF Module TTL UART and USB
Long range FHSS 250mW RF module
BV250RFL Long Range 250mW FHSS Transceiver for FPV, LRS, RC robots or other projects.
The BV250RFL RF Module combines a state-of-the art low power Analog Devices ADF7020 chip-based-transceiver with a powerful multipoint-to-multipoint frequency Silicon Labs C8051F311 protocol controller to form a complete wireless communication solution. With a simple UART interface, a 132.5dB link budget, and very low power operation modes, the BV250RFL module is excellent for FPV, telemetry, LRS, RC, robots projects and any other application requiring reliable communications around buildings but running off a battery (Range exceeds 5 miles + LOS with a -2 dBi gain 1/2 wave dipole antenna life and low cost. The module can operate as a transparent wire replacement solution; it can also operate in a peer-topeer networked mode that supports node addressing and assured delivery. Data is validated usingan internally generated CRC-16 and encoded using a proprietary algorithm. Multiple modules can operate on the same channel because of the built-in carrier-sense-multiple-access (CSMA) feature inside the on-board controller. The module allows users to select the best data rate to optimize the application’s data throughput and range requirements. The module has a raw maximum RF data rate of 152.23kbit/second and can be optimally matched to the UART data rate, which can be programmed from 2.4 to 115.2 kbit/second. The BV250RFL module employs frequency hopping spread spectrum (FHSS) modulation. There are thirty-two separate hopping channels in a hopping table, and the designer can program the module to use one of six hopping sequences. The module has been equipped with four variable power adjustable steps and automatic gain control (ADC) that allows for multiple modules operating in close proximity. The module has two digital RSSI registers available to the user.
