M5Stack Official Cardputer Kit with M5StampS3 - Pocket Computer Development Kit - ESP32-S3, 56-key keyboard & a 1.14"" screen, Compact, Grey

Why did you pick this product vs others?: Works great as a learning toy, can be used with SD cards which you could load with multiple operating systems The more powerful m5 stamp sips power, this thing lasts about 2 weeks before needing a charge. Literally fits in your pocket and could be used for multitudes of random tasks.

Arrived sealed in plastic. SD card slot does not work. Tried three 32 GB micro SD cards, formatted for FAT32, tested for write/read functionality and none will work with the Cardputer. Update two stars to five stars. Default app was unable to see SD card. After loading M5 burner SD card works without issue. Compact with allot features. Cardputer feels solid and well made. Shipping was fast would not hesitate to repurchase.

Great little computer. Make sure you have the right firmware. A background in electronics and programming helps but not 100% necessary.

Very cool little device. Might not be for everyone, but it has lots of potential. Have not spent a lot of time with it. Loaded a few programs and they worked fine. Seems to be built well.

Nice compact with a lot of possibilities

Flawless presentation and tool. Recommended.

My first M5 device was the Stick CPlus2, amazing device but this is about the cardputer : Compact yet feels comfortable and sturdy even in my large hands. Probably the most significant tactile thing about it is how sturdy it feels...is. Heavy, Seamless, SOLID, nothing rattles, nothing is loose, it feels more like a small cell phone with a rigid case on it than what you'd expect from the photos. The performance...I've only used the factory and Bruce firmware. Bruce is a hacking firmware with tons of functionality my favoriate on my stickc+2 so naturally threw it on the card immediately and was happy to find a ton of additional functionality as you'd expect. Battery...impeccable going on 3 days or so of playing with it periodically. Today I did a wardriveing session for over an hour with it. The battery is currently sitting at 80% and I have not plugged it in a single time since receiving it. M5Stack devices cannot go wrong. I have an Atom arriving tomorrow. 3 Mt devices in less than a month if that gives you an idea of how impressive they are especially for the price.

The benefits of having added this fantastic little device to the go-bag are innumerable. It's a fun gadget for beginners and useful (sometimes invaluable) tool for professionals. *It is NOT a "dolphin-toy" alternative, lol.. though supplemental hardware can be modded in order to make something similar and in some cases even better IMO.

Very well build, great firmware support. Awesome little device.

Arrived in good condition and worked well for 2 weeks from delivery. The SD card functioned as expected until it failed to be detected after two weeks, despite appearing properly mounted. No visible damage to the pins. Afterward, the charging circuit failed and stopped charging entirely. I had to replace the BMS chip (originally TP4057 with 57B3 marking). Soldering a new chip didn’t resolve much, except for slow charging same as ESP32 chip having issues. Ordering is up to you, but this issue may not apply to all units. (Not to mention had some missing resistors and capacitors not critically)
