CHAPTER 1: PURPOSE OF THIS DOCUMENT CHAPTER 1: PURPOSE OF THIS DOCUMENT This document aims to assist beginners in the first-time programming of ESP8266-EVB, ESP8266-EVB- BAT, or ESP8266-EVB-BAT-BOX, via Arduino IDE. Experienced ESP8266 users would probably find this document redundant. -
Page 5: Chapter 2: Requirements
2.1.2 Power supply adapter 2.1.2 Power supply adapter The ESP8266-EVB board gets powered via the barrel power jack named “PWR”. You need to apply exactly 5V DC. The corresponding power supply plug (or female jack) that fits the DC barrel has 2.1mm inner diameter and 5.5mm outer diameter. -

OLIMEX© 2017 ESP8266 with Arduino IDE • the cable needs to fit the pins of UEXT connector of the board – if it has free female leads, for example; • the cable has the proper driver support for the operating system of your personal computer. -
Page 7: Chapter 3: Setup
The hardest part of the connection is probably connecting the USB<->serial cable to the UEXT connector of ESP8266-EVB. The important part here is to connect the GND of the cable to the GND pin (#2) of the UEXT connector. Then TXD of the cable to RXD of the UEXT (#4). Finally, RXD of the cable to TXD of the UEXT (#3). - Page 8 OLIMEX© 2015 ESP8266 with Arduino IDE Page 8 of 15...
