Giới thiệu Denshitaro Kit phát triển ESP-WROOM - 02 development board 2.4 GHz Wi - Fi module Micro USB D00-268

It is a development board equipped with ESP - WROOM - 02 Wi - Fi module and USB - serial conversion IC FT 231 XS.
Since 3.3 V output regulator, reset switch, operation mode switching switch are installed, you can use ESP - WROOM - 02 Wi - Fi module immediately.
You can connect to the bread board by soldering the pin header. Pin header is attached.
- Features of ESP-WROOM-02
- Supports IEEE 802.11b / g / n (2.4 GHz)
- Low power consumption 32 bit MCU installed
10 bit A / D converter installed
TCP / IP protocol stack installed
Various interfaces such as SDIO, (H) SPI, UART, I 2 C, I 2 S, IrDA, PWM GPIO are installed

Under 10 uA in deep sleep mode, less than 5 uA at power off

Less than 2 ms from startup to packet transmission

Standby power consumption less than 1 mW (DTIM 3)

+20 dBm output (when using 802.11b)

-40 ° C to 125 ° C

FCC, CE, construction design certification acquired

USB: MicroUSB

Equipped with FT 231 XS

Reset switch, operation mode select switch installed Operating voltage: 3.3 V

- Power pin
VIN pin: Used to take power from other than USB. 3.7 to 6 V
VOUT pin: The name of the 5 V pin has been changed to the VOUT pin. (2016.01.08) When supplying power from USB, 5 V is output. When power is supplied from VIN, the voltage of VIN is output from VOUT.
When reset button is pressed, it will be reset. The mode switching button is connected to IO pin 0. When IO0 is pressed, IO0 goes LOW, and when it releases, IO0 goes HIGH. When IO0 is reset to HIGH, it starts up in the firmware execution mode, but if IO0 is reset in the LOW state it starts up in the firmware write mode.
