That would be nice just put in Nano 33iot or 33 BLE or 33 BLE Sense , and connect via bluetooth or wifi.(including IMU and even magnetometer for the BLE types, and the extra speed available )
Two changes needed A and B:
A: Supply 12/15v (or 5v from WAS power supply) to v-in on pin 15 , which is not connected on PCBv2. Nano 33 wants between 4,5v and 21v on v-in (Nano 33 has no connection to pin 12 or as they say, normally NC). Pin 12 position will have 3.3 v on PCBv2 when IC3 is changed as follows.
B: shift IC3 to a 3,3 v regulator in order to supply ADS1115, it can work on 2v to 5v. R-783.3-1.0 Recom Power - Voltage Regulators - Switching - Distributors, Price Comparison, and Datasheets | Octopart component search
Alternative B: cut away 5v connection line to ADS1115 and feed it with 3.3v from nano +3v3 power out.
If DOGS2 is used it must be connected as Brian suggests in the connection schematic.png, png is supplied with the AOG download.
Here they tell that md13s is 3,3v compatible. 13Amp 6V-30V DC Motor Driver
