Description
A board with ESP-12 WiFi module with goldpin connectors. There are 9 GPIO, 1 analog input and pins RX, TX, RESET, CH_PD, power and ground. On the board there are also LEDs, photoresistor and 3.3 V voltage regulator. Additionally, a basket is attached to the system, which allows for power supply from three AA type batteries.
Features of the Yellow Board with ESP-12
- It has 19 goldpin raster outputs 2.54 mm:
- 9 x GPIO - digital outputs/inputs
- 1 x ADC input - D/A converter
- UART (TX, RX) - for communication with e.g. Arduino
- CH_PD pin
- VCC - 3.3 V supply voltage
- GND - system weight
- Default communication speed UART: 115200 bps
- Jumper to connect GPIO0 pin to ground
- Built-in LEDs, including one RGB LED
- Installed light sensor photoresistor connected to analog input
- Connected 3 AA battery cage to power the system
- Equipped with a built-in PCB antenna
- Dimensions: 51 x 42 mm
Connection
The module has ESP-12E module connectors fora 2.54 mm goldpin raster strip.
| Pin | Description |
|---|---|
| TxD | UART serial interface transmitter. |
| RxD | UART serial interface receiver. |
| GPIO x | GPIO output (digital input/output) with a consecutive number. |
| Jumpers | Combines GPIO0 with weight. To update, you should enter a low state (i.e. leave a jumper). |
| GPIO 15 |
GPIO No. 15 with special function: In the normal and programming mode, the low state must be specified (connect to GND). |
| ADC | Analogue-to-digital converter input - connected to a built-in light sensor - photoresistor |
| REST | Reset the system. |
| CH_PD | Power down - when you enter a low state, you go into sleep mode.
To update, enter high state (3.3 V). |
| VCC | Power supply - 3.3 V. |
| GND | The weight of the system. |
Software update
In order to establish communication with Arduino or through AT commands, we recommend to update the software usingXTCOM_UTIL software. To do this:
- Download thesoftware from our website
- Connect the pins on the module:
- GPIO0 to ground - with a jumper
- GPIO15 by weight
- REST with VCC
- CH_PD with VCC
- Connect the ESP module via USB UART converter
- In the program select Tools ->Config Device
- Select the appropriate COM port, open it and connect to the ESP chip
- Leaving the Config Device window open, select API TEST ->Flash Image Download
- Select the firmware: ESP8266 v0.9.5.0 AT Firmware.bin and upload by clicking the Download button
