Thank you.You re right, i send that post after i tried that module. That HCSR-04 module isn't for Grove, it use 4 pins (VCC, ground, trigger pin, echo pin) . It works very well but.. This is my project : i have a mini-robot made with arduino (Uno, motor shield, ultrasonic sensor, servo) and i want to make it again in M5Stack and micropython context. So i bought the GOPlus element that provides controls for 4 servos connexions, 2 independant motors, 3 more grove ports. The problem is : when i use at the same time 1 servo and the basic 4 pins Ultrasonic function, the Echo Pin creates an ERROR on the M5Stack . That s why i wanted to try the grove Ultrasonic. But it s using only 1 pin for trigger and echo.

I don't know why but, now i have the SD card items in Advanced Menu. May be because i plugged once a SD card ? The white cross icon to add UNITS is here too. I ve notice that : when modification is done with Blocky and i save the file : the saved file is OK, when the same modification is done with micropython : the file can't be saved. As if the micropython screen wasn't really a part of the UIflow. Related to the issue n°4 above ??
