coil current
3.5V - 6V battery powered operation range
Li-Ion cell charger via USB-C
ESP32-PICO-D4 processor with integrated WiFi and BLE capabilites
UART and USB-C for serial communication and programming
StealthChop2 silent motor operation
Stall detection StallGuard4 in StealthChop mode
CoolStep smart current control

I might... But at the moment don't have stepper motors or previous experience with them. It would be a good opportunity to learn, though.

An ESP32 with a motor controller in a small module - that is a lot of functionality.
I tend to shy away from stepper motors, but this is a great solution if you have a need for one.

Never tried using a battery powered stepper motor so trying this eval board would be interesting. Unfortunately, too busy for the rest of this year.

I voted "maybe". This is because I'm not versed in stepper motor driver boards - yet. As Shrek say, "It's on my To Do List!" I would definitely follow any RoadTest reviews.

It seems like a new development board...

Not too much docs.

Maybe... not too sure.

It's for IoT, and I"m not the most experienced in that field...

This is a very interesting product. I am currently working on a retrofit/recycle project that is battery powered with multiple stepper motors. This would be a great opportunity for me to test out this device.
