A temperature and humidity sensor board developed by Robolab.
There are two versions. Both have an ESP8266 and a DHT22 sensor.
This version has to be power externally by micro-USB or with the JP2 serial port (in th left).
The model of the ESP8266 is a ESP07. This is the pinout.
- In the JP2 port you can connect an FTDI USB to serial.
The definition of the JP2 (in order up to down) is the following: GND GPIO0 VCC GPIO3 (RXD 0) GPIO1 (TXD 0) GPIO16 (WAKE)
An example on connection with a FTDI is EcoWin | FTDI GND -> GND GPIO0 -> CTS VCC -> VCC RXD 0 -> TX TXD 0 -> RX WAKE -> DTR
-
You need to install ESP8266 Boards library.
-
Select "Generic ESP8266 Module" and copy this configuration.
-
To enter the programming mode in the ESP266 you need to press the followings buttons in the board:
- Hold "Program"
