I hope you took away lots from this video and you managed to get your Xiao to work. Let me know below! PS. WANT TO LEARN CODING? CHECK MY NEW RU-vid CHANNEL! bit.ly/3tku2n0
I'm currently going through the Elegoo Uno R3 tutorials on my channel but seeing the size of this thing makes me want to switch. Perhaps in the summer I'll get this, thanks for a great video.
On the Seeed Studio site they sell this for $5.00. They have also developed ArduPy a combo of Arduino and Python. Please check it out and consider doing a video on it?
The title is slightly wrong! Actually the arduino the smallest arduino board is the arduino PICO, what is roughly 1.52x1.52cm. This one is still really small!
It's first pin next to the led's are 5v - Gnd - 3v3. It will power modules requiring 5v from that corner pin. The two corner pins next to the USB C plug are not labelled on the sticker due to the size available and also the chip cover doesn't allow for the sticker to line up with the first and last pins. Try a multimeter on the power pins rembering that the ground is in the centre of the 5 and 3.3 volt pins.
When you power the board through 3.3V pin, does it also charge the battery if the USB is plugged in ? Or does it have to be plugged at the back at Bat+ and Bat- ?
Love your Chanel. Very interested in this board. Got a load of projects that don't require fast processing butt require accurate analogue input measurement and digital / relay outputs. Is this a good choice? Look forward to possibly using Python?
I think yes. Check the SAMD21G18 datasheet to see if the resolution of the ADC is enough for you. Python works, but it is slow in this board, and the RAM is barely enough.
@@Educ8s Yeah, seeing the specs (RAM and flash) I thought running python (micro- or other flavour) might be a bit of a stretch. Too bad, for my hobby projects I've completely switched away from Arduino to Micropython. Fun board though for low power/small size applications.
Hi...Have you tried it(xiao), without led? , in running and sleeping mode ?... Any know if you can use rtc, by direct programming in your flash? ...thank's
the processor these use implement the cortex M0+ isa, which has WFI and WFE instructions that put it to sleep pending software or hardware events. The arduino studio SDK contains examples and a library called "EnergySaving" that use these.
1mA in sleep mode is actually waaaay too much. In my opinion this is a common problem of most available dev boards, even the original ones by sparkfun and adafruit. Why place chips that have fancy sleep modes on pcbs that have high quiescent current? I don't get it.
Yes, it is much but I didn't remove the power LED which is ON all the time. If we remove it, we can reduce the power draw to about half I think. Other than that you are absolutely right. Why is it so hard for a company to develop a board that use the deep sleep capabilities of modern chips? This is something all makers want, not just more speed and FLASH and RAM.
