★Add battery power detection circuit. Use ADC2_4 (GPIO 13) to read battery voltage, Please get the example link from the product description below
[This is an upgraded version WiFi Kit 32! ] 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 battery power detection circuit. Use ADC2_4 (GPIO 13) to read battery voltage. Please get the example link from the product description below
5. Add Vext power output pin, users can use this pin to drive some external device (sensor, motor etc.), when system need into deep sleep mode, Vext can be turn off. This pin was controlled by GPIO21, for example: Turn ON: digitalWrite(21, LOW); Turn OFF: digitalWrite(21, HIGH)
6. New WiFi Kit 32 pinout diagram; 7. New WiFi Kit 32 schematic diagram; 8. Circuit optimization, system more stable; 9. Better power manage system design
