ESP-01 Programming adapter

This weekend i finalized my ESP-01 programming adapter board.

Protoboard for ESP-01 ProgrammingThe circuit is a little bit changed compared to the diagram posted earlier in the post “ESP-01 Module”

I added two terminals for connecting external 3,3V and GND. This change I made because I could not get the wifi function on the ESP-01 module to work, when the module was powered through the USB to TTL board.
On the left you see the board i made.

I have not desided yet, but maybe I will add two terminals for wire connection to the GPIO0 and GPIO2.

 

 


ESP-01 module

I just received two off these small ESP-01 boards.
They are part off the ESP8266 family and have relly nice specs:

  • ESP8266 chip.
  • 2 dedicated GPIOs.
  • Serial comms (or 2 additional GPIOs).
  • Pin connectors.
  • Arduino-compatible.
  • PWM, I2C, UART, OneWire.
  • On-board WiFi + printed antenna, 802.11 b/g/n, 360m range.
  • Able to become a wireless access point.
  • Lua and Arduino firmware available.
  • Able to run a web server.
  • Dimensions: 24.75 x 14.5mm.
  • Power: 3.3v. (important!!)

Instruction for flashing this little fellow can be found on http://www.esp8266basic.com/flashing-instructions.html
And I plan on building this flaching setup
