Hi folks,
I want to build a simple 9DoF sensor that will send data via WiFi/BLE to an iPad. I would like to use the 1"X1" form factor to stack boards and a battery. The transmission distance would be 20’ maximum. Any suggestions as to which hardware I would need to purchase? I also assume that I can program the project using the Arduino IDE. I have been programming Arduino hardware for quite a while soI am sort of familiar with their hardware offerings but have found better support here at SparkFun.
Thanks for any help with this!

There are a number of small MCU boards that have an IMU and WiFi or Bluetooth built in. Arduino makes the Nano 33 BLE Sense (sold by Sparkfun), Adafruit has several different ones (Clue, Feather Bluefruit Sense) , Seeed Studio Xiao BLE Sense, etc.
All you need to do is write some code, and there are examples to get you started. Adafruit examples are probably the best.

Adafruit is on the top of my BS list. I spent a bunch on a suite of their boards and in almost a month haven’t gotten them to work. Their forums and support folk are less than helpful, except for a couple of people who tried but couldn’t get me there. I will have lost a 5K prototype project as of tomorrow 10/21 and my only hope is to find another set of boards that I can switch over to and get the project back on track if the backer is even willing to give me another shot. I’ve done quite a few Arduino Uno/Mega/Nano projects but none using WiFi/BLE so it’s kind of where no man has gone before for me.
Thanks for the suggestions and I’ll see if I can get this back on track

As for our in-house stuff…the main constraint in your list is the 1"x1" size; you could stack these 2 and probably have a decent time 
SparkFun Qwiic Pocket Development Board - ESP32-C6 - DEV-22925 - SparkFun Electronics (BLE/WiFi, Lipo port)
SparkFun 9DoF IMU Breakout - ISM330DHCX, MMC5983MA (Qwiic) - SEN-19895 - SparkFun Electronics (9DoF)
Then just grab a Lipo + qwiic cable and follow their hookup guides, then calibrate, etc
You already got the suggestions that you were looking for. Here is a design that you may also see for reference. ESP32 MPU6050 Monitor - Share Project - PCBWay
This board has an ESP32 and an MPU6050 gyro and accelerometer. This is created to monitor vibration and tilt with the MPU6050 sensor. You can make a similar PCB with the components that you choose.
Hi,
Jeez! I wish I had found this $225 ago. This is exactly what I was looking for! The only question I have is whether the completed board is available. My soldering skills have dramatically down graded after I hit 65. Any ideas on if the completed project is available?
Thanks,

@TS-Russell ,
Thanks for the suggestion. I picked up the suggested boards as well as a Lipo and charger board. I used to be quite a hardware geek but have lost those skills. I can still however sling code fairly well but could always use some docs/code to get me started. Why re-invent the wheel.
Best,
Joe B
