Vollgo VG297STS-C1

The VG297STX series modules are single-chip wireless transceiver modules operating in the globally licensed 2.400~2.483GHz ISM band. Incorporating a high-performance 2.4G chip, the chip integrates RF transceiver, frequency synthesizer, crystal oscillator, modem, and other functional blocks, supporting point-to-point, multi-node networking, and communication modes with ACK. Transmit output power, operating channel, and communication data rate are all configurable.

• Low power consumption: TX mode (2dBm) operating current 19mA; RX mode operating current 15mA; sleep current 2uA.
• Highly integrated, easy to use: built-in partial link layer communication protocol; minimal parameter register configuration required.
• Excellent performance: RX sensitivity of -91 / -87 / -83dBm at 250K / 1M / 2M bps; max TX output power up to 13dBm; strong interference immunity, high adjacent channel rejection, good receiver selectivity.
