WIFI-10 module for DWIN Cloud Development Platform ESP8266 + 4MB flash 2.4-2.5G Adapter
The V2.0 hardware package definition is shown in the figure above, and the pin pitch is 2.0mm.
the difference:
IO14/SCL: I2C interface SCL, WIFI module output
DL/SDA: WIFI module download enable, internal pull-up resistor 10K. When the module is powered on, this pin is low, which means it enters the boot mode. Just use the suspension normally.
For the SDA of the I2C interface, if the I2C interface is enabled, the TX function of UART1 needs to be disabled.
1.Characteristic parameters
Main chip ESP8266+4MB Flash
Support 802.11 (2.4 GHz), frequency range 2.4G ~ 2.5G (2400M ~ 2483.5M)
PCB onboard antenna
Maximum transmit power 14dBm
Serial port transmission rate 921600bps (device-side transmission data rate)
2. Hardware interface
The V1.0 hardware package definition is shown in the figure above, and the pin pitch is 2.0mm.
The WIFI module should have 7 pins in total, VCC (3.3V), GND, TXD, RXD, C/D, TXD_C, and /RST.
TXD, RXD: data channel, baud rate 921600.
TXD_C: It has nothing to do with the business, the internal information printout pin, which is left floating.
C/D: WIFI module download enable, internal pull-up resistor 10K. When the module is powered on, this pin is low, which means it enters the boot mode. Normal use can be suspended
3V3, GND: Need to ensure a peak current of 300mA.
/RST: Reset pin, need to connect the reset chip to reset reliably. Low level resets the WIFI module.
