Re: Pyboard D-series accelerometer-gyro ?

1. Yes, far better!
2. It has no accelerometer, you‘ve got to buy one.

Re: Problem with socket.getadrinfo() over mobile hotspot

I had the same problem, could you try to use the IP Address instead of the name?

Re: MICS-6814 I2C grove

I didn‘t search for a library but I skimmed through the code of the Arduino Lib. Looks like easy I2C communication which you can easily port to Micropython if needed. Sp even without a library this is a simple task!

Re: I can't access microSD cards with Pyboard 1.1

I would have done the exact same think. After a little bit of testing you surely will know if it‘s stable enough.

Re: I can't access microSD cards with Pyboard 1.1

I though that maybe they forgot one pin on the hardware side, and after looking at the schematic I remembered that there are two kinds of microsd connectors, with and without detection switch. So I tried to forcefully change the detection pin and it worked :-) The next step would have been to use a ...

Re: Will 3.6 volts fry my pyboard

Digital input of the Pyboard are 5V tolerant. So no problem here.
The analog inputs are not, so beware.
But I'm pretty sure that 3.6V won't damage anything...

Re: I can't access microSD cards with Pyboard 1.1

The problem is that the chinese people "forgot" to connect the Pin A8 which is the SD Detection Pin. I assume they opted for a cheaper microsd connector which simply does not have such a switch (0.00 Cent saved!). You can use your SD-Card like so: mport os import pyb import machine # Forces the pin ...

Re: I can't access microSD cards with Pyboard 1.1

Even sd.present() does not detect the SD Card, so it seems to be a hardware problem? Maybe the chinese guys did something wrong when copying the schematics. Are there any ways to find out whats wrong here? Maybe we can speak SPI to the microSD Card?

Re: I can't access microSD cards with Pyboard 1.1

I can confirm the problem. I also got a Crow Pyboard (which seems to be a cheap version of the Pyboard 1.0 or 1.1 - I'm not sure) and it also does not mount the sd card whatever I do. I have another clone (not Crow) which has absolutely no problem to mount the sd card. So I'm pretty sure the SD card...
