Me shield & Raspberry PI 3

#1

Hello everyone,

Excuse me for my language, I am French.
The “Me Shield for Raspberry Pi” module is compatible with it you Raspberry PI 3?
Feeding an “Me Baseboard Orion” powered by a “Battery Holder for (6) AA” is sufficient to power the Raspberry PI3?
The Raspberry PI 3 integrate WiFi and bluetooth. I would therefore call on the wifi card without having a power problem.
I think buying the following kit: Starter Kit Officiel Pi3.

Also, I would use the module “Raspberry Pi camera module”.

Cordially

Hi JG42,

The Me Shield for Raspberry Pi works with Raspberry PI 3
Please refer to the info in this link for the wiring and power:http://learn.makeblock.com/en/me-shield-for-raspberry-pi/

Thank you for your reply.
So I would not worry about a battery supply?

The link you gave me it to speak of 12V. My box of 6 AA batteries (1.5V) provided that 9V.
When do you think?

Hi JG42,

I suggest that you may give a test yourself.
Normally 6 AA batteries for a single me Orion or me baseboard is enough.
While the instruction, it ask for 12V, it must been tested with 12V, if you want to use 9V, you may just give a test.

Hello,

Thank you for your reply.
Just place order and I will test myself.
I’ll let you know once you receive the equipment.

Have a good day

If you are using Orion wirh RPi3 you may like to read about some first-hand experience of its use in the reviews On Me Shield For Raspberry Pi that I have submitted under the Shop section of this website.

Hello,
I received my material.
I confirm the proper functioning of my Raspberry PI 3 with my Baseboard Orion.
By cons to access the UART connection of Raspberry must use “/dev/ttyS0” is not “/dev/ttyAMA0”

from megapi import *
bot = MegaPi()
bot.start('/dev/ttyS0')

Then you have to disable the use of the port block and core frequency to 250:
Add in the file “/boot/config.txt”:

uart_enable = 1
ft3 = dtoverlay-disable-bt
core_freq = 250

As I do not use my bluetooth, I disabled the service “hciuart” start. He posed problems (using “/dev/ttyS0”):
sudo systemctl disable hciuart

Everything works and no power problem with my batteries
