- A-MPDU & A-MSDU aggregation & 0.4μs guard interval
- Wake up and transmit packets in < 2ms
- Standby power consumption of < 1.0mW (DTIM3)
- Identical to adafruit item 2491
- This module requires a 3.3 volt supply for VCC, and 3.3V logic.
- It is not 5V tolant,Connect RX or TX on 5V Arduino will destroy this module.
- You must use a logic level converter, or a 3.3V Arduino
- The 3.3V supply on the Arduino Uno has inadequate current capabilit to power this module.
- You must provide a separate,higher 3.3V supply(about 300mA or better)
