RE: B-Robot BRAIN SHIELD Scheme and layout
I was trying to order parts but some of them are difficult to get. Would I be able to use the Brain Shield with other sonar sensor ? Would that mean I would have to change code ?

Hy,

you could use any Sensors which give you a Analog Signal as Output.
@ example: I use the Sharp GP2D12 InfraRed Distance Sensor.

U also can use a HC-SR04 Ultrasonic Sonar but then you musst chance the Code.

Hello JJRobots Team and everyone,

Regarding the new version of the brain with support for the ESP8266 module, I assume the pinout/schematic to interconnect the ESP-12E is about the same, right?
I mean, the connection between the new ESP8266 wifi module and the Leonardo is made using only:

3.3V
GND
TX
RX

Is this correct?
Thanks.

Hi Saturno,
Yes, basically. But there are other lines we are using to control the ESP too. Take a look to the new design (file attached). We will upload it to github asap

Hi JPedro,

Thanks for your reply, the schematic makes it more clear.

Are you using he Leonardo 3.3V to power the WiFi module, or is it powered from another 3.3v regulated line?
My question is because this module is (or can be) "a little" power hungry :-)

Thanks for your help.

Welcome!
There is a dedicated 3.3V power supply for this Wifi Module, as you said, it is a power devourer :-)

RE: B-Robot BRAIN SHIELD Scheme and layout
Hallo everyone,

first...i really really like that project...its amazing!!
i have also a problem with the ESP-modul....especially with the wiring.
The new design, shared by jpedroc, makes the wiring much more clearer but i have a few more questions. I hope you can help me.

There are four additional wires on Reset, GPIO16, GPIO0, CH_PD going to ESP EXTERNAL RESET/FLASH.
- Do i have to programm the ESP before (I thought this happened in the main program)?
- How i have to wire these ESP EXTERNAL signals with the leonardo?


Many thanks in advance!!

Daniel

Hi Daniel,
Those are lines to reprogram the ESP module if you want to update the firmware or use your own modifications.
You do not really need to connect or use them.

Hi,

I uploaded / shared the pcb on OSHPark: https://oshpark.com/shared_projects/EO4ANIN8

Also, I ordered an Xbee to ESP8266 adapter: https://oshpark.com/shared_projects/rCVkThMB
