The single sided self etchable pcb is designed to power the ESP-module, has a reset and flash (program) button, the necessary pull-up/ pull-down resistors and a USB-to-serial IC (CH340G) to connect the adapter board via micro USB to the USB port on a PC. You can also wire a serial connection directly to the RX/ TX module pins.

Please bear in mind that the module pins have a 3.3 volt signal level. If you use a signal source with 5 volt (e.g. an Arduino driven by 5 volt) the RX-pin has to be driven by a voltage divider or any kind of level shifter.

The module can be connected to a power source via USB, the Vcc-pin of the module (max. 3.6 volt) or via the Vin-pins (max. 12 volt, min. 4.8 volt).

As the pcb is single sided you have to connect three jumper wires on the bottom (see Eagle-files for directions).
