NRF905 Wireless Module (PTR8000+) Wireless Digital Transmission Module 905 Module

Fully compatible (PTR8000+) module [product name:] NRF905 module [Product unit:] (including antenna) [product introduction:] communication module Application areas: Vehicle monitoring, remote control, telemetry, small wireless network, wireless meter reading, access control system, cell paging, industrial data acquisition system, wireless tag, identification, contactless RF smart card, small wireless data terminal, security fire prevention system, wireless remote control system, Biosignal acquisition, hydrometeorological monitoring, robot control, wireless 232 data communication, wireless 485/422 data communication, digital audio, digital image transmission, etc. Features: The three-band transceiver is integrated, the working frequency is 433/868/915MHz GMSK modulation in the international ISM frequency band, and the anti-interference ability is strong. It is especially suitable for industrial control occasions. It adopts DSS+PLL frequency synthesis technology, and the frequency stability is excellent and the sensitivity is high. 100dBm low operating voltage (2.7V), low power consumption, standby mode is only 1uA, can meet the requirements of low-power devices, maximum transmit power up to +10dBm, with multiple channels (up to 170 or more), especially for multi-channel operation Special occasions can work up to 76.8Kbps The minimum number of peripheral components (only 10), basically no debugging. Due to the low transmission power and high receiving sensitivity design, the use of open space is up to 1000 meters* without using a license. * It is related to the specific use environment and component parameters. Electrical characteristics: nRF905 operating frequency band: 433/868/915MHz Number of channels: 170 Function: Transmit/Receive Frequency stabilization mode: PLL Modulation method: FSK/GMSK Maximum output power: +10dBm Sensitivity: -100dBm Maximum working speed: 76.8Kbit/s Working voltage: 2.7--3.3V
