Description:
What’s the Upgrade of New WiFi Kit 32?
1. 4MB (32M-bits) FLASH upgrade to 8MB (64M-bits) FLASH;
2. Better 2.4GHz antenna design and impendence matching;
3. Basic low power design (800uA in deep sleep);
4. Add a battery power detection circuit.
Use ADC2_4 (GPIO 13) to read the battery voltage.
Please refer to this example:
