MakerFocus ESP32 Development Board Upgraded Version 8MB Flash, ESP32 WiFi Bluetooth, ESP32 OLED 0.96 Inch OLED Display CP2102 Internet for Ar duino ESP8266 NodeMCU

★Increase the battery power detection circuit. Use ADC2_4 (GPIO 13) to read battery voltage, please get it from product description below.
[This is an upgraded version W i F i 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.
8. Circuit optimization, system more stable.

BOOST YOUR COMPUTER'S SOUND. Equipped with an XMOS U30881C10 USB receiver chip, the K3 is capable of decoding up to 384kHz/32 bit PCM and native DSD256..
FINEST COMPONETS FOR MAXIMUM POTENTIAL. The combination of high-performance AKM AK4452 DAC with low-distortion op-amps OPA926x2 and professional-grade LPF TI OPA1612 make up for a outstanding performance..
MODERN USB TYPE-C INPUT INTERFACE. The USB Type-C ensures a more reliable and stable connection. Moreover, the K3 implements overvoltage protection (OVP) and a double-filter circuit to ensure power supply stability..
TWO MODES OF USB AUDIO. In high-performance applications, you can use the 2.0 mode to enjoy up to 384kHz/DSD 256 decoding.
For certain situations, you can use the 1.0 mode to enjoy up to 96kHz/24-bit PCM audio without needing any drivers..
ADC VOLUME CONTROL The use of ADC volume control can not only eliminate channel volume imbalances, but also allows the user to smoothly adjust the volume to a more accurate and finer degree to boost headphones of all kinds of sensitivity for a variety of listening needs..

ATmega32U4 microcontroller: The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface..
The acceptable voltage range is 5 to 9 V..
On-Board micro-USB connector for programming.
This tiny little board does all of the neat-o tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite pro-compatible boards but this little guy can go just about anywhere. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC..
This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled. We've also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit..
