@anuj01 Another alternative is to use the M5 official IO expander unit.

M5StickC has an I2C grove port, and you can connect this unit to it. I have tested and it works. Good luck.

@ipodlux For the time being, I stopped using uiFlow (or Python) for IMU related project. It is not reliable and it is slow. Use Arduino IDE, you will have a much faster code and reliable result.

@mikeh Yes you can. Please follow this tutorial by @lukasmaximus

@m5stack said in [Solved] GPS Unit (AT6558):

@m5stickfreakler if the "old" GPS has problem, pls contact our store.

I bought a GPS Unit from Aliexpress and it seems old since I faced the same problem with @M5StickFreakler. What store should I contact for this issue?
Just now I contacted the M5Store from the Aliexpress homepage.

@rexlee I assume you use Arduino IDE. What example did you compile for your M5Stick C? If it was your own code, then please upload the code so other members can take a look.

@m5stickfreakler I had the same problem, but up to now, there is no solution or support from the M5Stack people. I used M5Stack Fire and Port C (UART) with UiFlow. If the M5Stack Fire were the problem, I hope somebody can check with other M5Stack cores (Grey or Black). If Port C were the problem, then changing the port may help. But your posting indicated that even if we change the port from C to A, still the GPS Unit is not working then either or both the product or UiFlow is not a good product. I hope there is an improvement in the future.

@ryanfobel said in DC Encoder Motor driver/Lego+ module connector type?:

Thanks to everyone who posted links to the mindstorms connectors, but I'm actually looking for documentation on the the connectors on the Lego+ board (6 pins, ~1.27mm pitch).

Have you checked this one:

@kees I bought with the brand Keweisi from Aliexpress a long time ago (same with the one mentioned by @ajb2k3 ?). But I could not find now. However, I found a very close one in Aliexpress:

10 in 1 Digital Dispay DC USB Tester Current Voltage Charger Voltmeter power bank wattmeter voltage tester doctor detector (462 Japanese Yen + 12 Yen Shipping to Japan).

I use a USB type watt meter. Please see below.

@m5stack Thanks. I am now experimenting with Base X.
