M5Stack Core2 microcontroller - review and start using it with Arduino IDE

[@boldvoltage639]

I've got stacks of ESP32's and probably all the other parts. I don't need an M5Stack Core2 MCU. But man.. I do want one... Glad you took it apart - thanks!ll

I don't see that the battery replacement would be an issue. There is no third wire for reporting any kind of status to the main board, and the board on the battery should be just a standard protection device, DW01. It's only there to implement a safety cutoff in case of fault outside the battery and prevent battery fire. It will also prevent battery deep-discharge condition. You should be able to use just about any battery on there, just check the charge termination voltage. You look at the size spec on there, 502728, and you can order an identical one, the basic standard ones that you get do come with protection. Or if you're retrofitting to a bigger enclosure, you can use whatever you can find, replaceable simple phone batteries (Nokia, Samsung - they have builtin protection), 18650s (available with a protection board installed) etc. According to the board topology printed on the sticker, which is just such a nice detail, you find an AXP192 PMIC on there which should manage the battery safely to begin with, but this is a DIY device so an extra layer of fat-finger protection is a good idea but there are no particular functional requirements on it. Do mind that when you order from a professional battery merchant who knows what they're doing, which is a good idea, the battery will travel on land freight only, so if it's from China, it can take several months.

Liked the video! And when I like a video I leave a comment to help with the KZbin algorithm. If I can suggest something to better the video is a lapel mike for the sound. Again I am not in 3d printing but I like all tech stuff and the knowledge. 👍🏻✌🏻🇨🇦

Interesting microprocessor and form factor Thanks for sharing your experience with all of us 👍😊

Thanks alot. It made my day at new project. Regards from Japan.

Wonderful overview! Love the channel!

For this version, u need to get bottom2 battery to get another Grove pin. I am thinking if I should get aws core2 that comes with bottom 2 battery. Overall , it's cheaper

Why the heck is the M5 Stack folder 2,74GB? In comparison, the library for the Microbit and other nRF boards is 480MB, and MightyCore is only 47MB. They really need to cut down bloatware, compilation time for the ESP32 in this board is unacceptable due to the mega fat library.

[@2kBofFun]

Just replaced 2.07 with 1.06 and that one is only 256MB.

So amazing review. Can I make a wifi router with 2 4g sim modules stacked on it, for fast internet by two network bonding? I am trying to make it stand alone by avoiding the bonding VPN service.

[@MiguelAngel-mf3yu]

hello, I would like to know how to charge it and how many hours it charges and how

[@MyTechFun]

You can charge it with phone charger or from USB on computer. Depend of the charger, but less than 1 hr is the charging time.

[@MiguelAngel-mf3yu]

@@MyTechFun does core2 have to be off or on? to be able to load it

[@johanncad7538]

Hello, Someone have un code example to conttol dac pin g25 and g26 about m5 core 2? I have to send a 2v on g25 and 3v on g26. Thanks, Joh

[@karenzambrano5973]

this core 2 has any Bluetooth?

where in eastern europe are you from?

Hi I am doing a project with the m5 stacks, can i reach out to you privately to ask some questions please.

[@MyTechFun]

Yes, my email is in about page (Yt desktop version)

But what is it? 😂😂😂
