Frequently Asked Questions
What wireless standard and frequency band does the SPWF01SA-11 support?
The SPWF01SA-11 supports IEEE 802.11 b/g/n at 2.4 GHz, with a built-in TCP/IP stack and UART AT command interface operating at 3.3 V, making it straightforward to add Wi-Fi to embedded designs.
Which host interface does the SPWF01SA-11 use, and what baud rates are supported?
The module communicates via a UART interface using AT commands, typically supporting baud rates up to 115200 bps. This allows any microcontroller with a serial port operating at 3.3 V logic to control the module without custom RF drivers.
In what types of battery-powered IoT applications does the SPWF01SA-11 operate reliably?
The SPWF01SA-11 suits battery-powered wireless sensor nodes, smart meters, and portable data loggers where the 3.3 V supply and low sleep-mode current—typically under 10 mA in standby—help extend battery life while maintaining 802.11 b/g/n connectivity.
