{jcomments on}The Esp8266-01 can be easily be programmed with the Arduino IDE if it is attached to a USB-TTL converter like the FL232. As I ordered my ESPs in bulk and plan to use them in a variety of projects in the near future I decided not to assemble a flash station (link here) on a breadboard but rather solder a small circuit board. This will not only help me mass-produce my ESP configurations, it is much rather a hardware equivalent of the small bash scripts I write to remember useful flags and oneliners.

Testbenching

Since this is my first project with an ESP8266-01s I want to test all the relevant parts before I feel confident enough to assemble my final project. First if all i wanted to test if the buck converters are stable enough to provide constant 3.xV for the ESP, even when confronted with different input Voltages. In a second step i want to test the signal strength of the serial output of the ESP and try to raise it to the 5V that are needed for the Roombas serial pins.
