		+	==Flashing custom firmware==
		+	You'll need to connect some kind of UART interface device to your PC or other capable device. '''RX''' pin of this device goes to board pin marked "'''U0 TX'''", '''TX''' pin -- to "'''U0 RX'''". '''GND''' to '''GND'''.
		+
		+	Connect '''GND''' and '''3.3V''' pins from diagram above to 3.3V PSU (up to 0.2A was needed during my test).
		+
		+	Connect '''GPIO0''' to '''GND''' and power on the device with PSU.
		+
		+	Flash the chip using [https://github.com/espressif/esptool ESPTool] or other preferred method.
		+
		+	Remove the power and disconnect GPI0 tie to the ground.
		+
		+	Done!
