- | The high voltage side is directly fed by whatever voltage is applied to the PCB Input. So it is only limited by the voltage accepted by the voltage regulator. The relay can be toggled by toggling GPIO13 on the microcontroller. The relay populated is a normally open one. If the relay is activated and the coil inside is energized, the LED by the relay will light up. This is not an indication that there is definitely a voltage at the high voltage output pad but you at least know the state of the relay. On the low side of the high voltage output a current sensor is attached. | + | The high voltage side is directly fed by whatever voltage is applied to the PCB Input.

+ | On the right side of the ESP-Chip are 4 pins located. These are labeled with GND TX RX and VCC. To program the board, you have to use a so-called FTDI or UART programmer. Connect the pins like so: | ||
+ | ^ UART/ | ||
+ | | VCC / 3.3V | VCC | | ||
+ | | GND | GND | | ||
+ | | TX | RX | | ||
+ | | RX | TX | | ||

+ | You are now able to program the board with the Arduino IDE. | ||
+ | The board is intended to work with Tasmota. If you want to learn how to flash Tasmota onto an ESP8266 you can read more here: | ||
