[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 |
1 | E103-W12C | E103-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. |
2 | Micro usb | Micro usb connects to AT command serial port. |
3 | Micro usb | Micro usb connects to the debugging serial port. |
4 | Pin | All available GPIO pins (except the flash SPI bus) are routed to the development board's pin headers. Please see Pin Headers for more information. |
5 | PWR_KEY | PWR_KEY power supply enable pin, high level enable, low level shutdown in sleep1 mode, normally plug in 3.3v on the left. |
6 | WAKE_UP | WAKE_UP sleep2/sleep3 external wake-up pin, valid on the falling edge, normally plugged into 3.3v on the left. |
7 | VDD_DIO1 | GPIOA1-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. |
8 | VDD_DIO2 | GPIOC6-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. |
9 | USB to UART bridge | Single-chip USB to UART bridge providing transfer rates up to 1 Mbps. |
10 | WAKE_UP2 | Grounding is not used yet. |
