What is the current limit for running servo motors? I am planning to run several continuous rotation servo at the same time.

Hi Tech Support,
I have a IO Expansion Shield for Arduino V7.1 currently connected to a SD card reader via I2C.
How do I connect the followings to the shield?
1. LCD screen (I2C)
2. DHT20 (I2C)
3. WiFi_IoT_Module_SKU_TEL0126 (I2C)
Possible?
Please advise. Thanks.
JaneYu If you need to use multiple IIC devices and the addresses do not conflict, you can use the IIC breakout module:

Can this be mounted on an ARDUINO UNO WiFi REV2 (https://store.arduino.cc/usa/arduino-uno-wifi-rev2)?
JaneYu Hi,
Yes you should be able to use the expansion
shield without any major issue.
Can i use 3 board together, Uno R3 + Sim 7000C + Gravity IO Expansion Shield + Water pressure sensor.
Can you suggest me with hardware diagram with this set..

JaneYu Hey,
You can stack the Gravity IO expansion shield on top of the SIM 7000C and then attach your sensors to the expansion board! You simply stack the components on top of each other in the following order : UNO, SIM 7000C, IO Expansion Board, Water Pressure Sensor
Hey, can i get the dimensions for this expansion shield. Thanks in advance
JaneYu what the difference between this and https://www.dfrobot.com/pro...
JaneYu The GPIO shield adds 16 GPIO digital pins to the board. However, the function of this IO expansion shield is mainly for simplifying wiring connection, as well as providing support for other interfaces, like Xbee, DC motor and APC.
Dear Sir, Hello, I have a power supply (6V/10A) to be connected to the external servo power port on the shield to feed 5 servos (1.0A continue load and 1.2A max peak per servo):
1) What is the max. current per servo this board was designed to support? (in continue not pick value).
2) What is the max. current the board can support when all servos are simultaneously active and under load? (in continue not pick value).
3) Is it possible to use the same power supply (6V/10A) for the on-board PWR port? (maybe the V it's a bit low, but the board will work anyway? what do you recommend?).
Could you please help me with these questions.
Thanks in advance.
JaneYu The Servo_PWR is connected to the digital 5V/GND pins directly, so there is no maximum current related to the shield, it is all depends on the servo you use and the output current your power supply has.
You may need an xBee Adapter to configure it: https://www.dfrobot.com/pro...
Then plug the xBee onto the socket of the IO expansion board and use normal Serial port to communicate.
JaneYu What kind of question do you have, we just find some information about the pin explanation of the module. Hope this can help you. https://uploads.disquscdn.c...
JaneYu Based on my understanding, the expansion board doesn't build with a usb port. After attached, will I still able use the usb port of the adruino and send data to pi?
JaneYu Actually DRFduino is the same Arduino board as UNO, they have the same microcontroller and the same pin outs, you can plug 6 analog sensors at the same time.
JaneYu please tell me the parameter of the capacitors
JaneYu You can find the capacitors value from the schematic
Hello!
Can you connect a motor shield or motor directly to this expansion shield?
JaneYu Hello!
I am currently working on a project and I need to figure out statistical data analysis. I am comparing speed and time. What is the best statistical data analysis should I use to compare speed and time? I am already using standard deviation. Also, I am not sure whether or not t-testing works for my project?
JaneYu **, I just need to connect my Arduino to my PC. I will host a mqtt server and I want to sent data from my arduino. Any suggestions? Cost Effective?
