E103-W12C-TB Ultra-low power WiFi module test kit

[Interface]:USB

[Size]: 55*38mm

[Introduction]:The E103-W12C-TB wireless module test kit is an entry-level development board for two serial port WiFi modules, using the E103-W12C module named for its ultra-low power consumption. This development board has complete Wi-Fi functions, and most of the module pins on the board have been led to pin headers on both sides. Developers can easily connect a variety of peripheral devices through jumpers according to actual needs, and can also Plug the development board into the breadboard and use it.

Serial number Main firmware                                  Introduction
1E103-W12CE103-W12C is a general-purpose Wi-Fi module using ceramic antenna. This module integrates a chip with 4 MB embedded flash. Since the flash is directly packaged in the chip, the E103-W12C module has a smaller package size.

4PinAll available GPIO pins (except the flash SPI bus) are routed to the development board's pin headers. Please see Pin Headers for more information.
5PWR_KEYPWR_KEY power supply enable pin, high level enable, low level shutdown in sleep1 mode, normally plug in 3.3v on the left.
6WAKE_UPWAKE_UP sleep2/sleep3 external wake-up pin, valid on the falling edge, normally plugged into 3.3v on the left.
7VDD_DIO1GPIOA1-GPIOA11 power supply is 1.8v-3.3v, the GPIO output voltage is consistent with this, and the jumper cap is inserted to the left.
8VDD_DIO2GPIOC6-GPIOC8 are powered by 1.8v-3.3v, the GPIO output voltage is consistent with this, and the jumper cap is inserted to the left.
9USB to UART bridgeSingle-chip USB to UART bridge providing transfer rates up to 1 Mbps.
